title: Go Developer Survey 2023 H2 Results date: 2023-12-05 by:
In August 2023, the Go team at Google conducted our bi-annual survey of Go developers. We recruited participants via a public post on the Go blog and a randomized prompt in VS Code, resulting in 4,005 responses. We primarily focused survey questions around a few topics: general sentiment and feedback about developing with Go, technology stacks used alongside Go, how developers start new Go projects, recent experiences with toolchain error messages, and understanding developer interest around ML/AI.
Thank you to everyone who participated in this survey! This report shares what we learned from your feedback.
gonew) appears to solve critical problems for Go developers (especially developers new to Go) and does so in a way that matches their existing workflows for starting a new project. Based on these findings, we believe gonew can substantially reduce onboarding barriers for new Go developers and ease adoption of Go in organizations.Go developers continue to report high levels of satisfaction with the Go ecosystem. A large majority of respondents said they felt satisfied while working with Go over the past year (90% satisfied, 6% dissatisfied), and a majority (52%) went further and said they were “very satisfied”, the highest rating. Longtime readers have likely noticed that this number doesn‘t change much from year to year. This is expected for a large, stable project like Go; we view this metric as a lagging indicator that can help confirm widespread issues in the Go ecosystem, but isn’t where we expect to first learn about potential problems.
We typically find that the longer someone has worked with Go, the more likely they are to report being satisfied with it. This trend continued in 2023; among respondents with less than one year of Go experience, 82% reported satisfaction with the Go development experience, compared to the 94% of Go developers with five or more years of experience. There are likely a mix of factors contributing to this, such as some respondents developing an appreciation for Go‘s design choices over time, or deciding Go isn’t a good fit for their work and so not returning to this survey in following years (i.e., survivorship bias). Still, this data helps us quantify the current getting started experience for Go developers, and it seems clear we could do more to help emerging Gophers find their footing and enjoy early successes developing with Go.
The key takeaway is that a large majority of people who chose to work with Go during the past year were happy with their experience. Further, the number of people working with Go continues to increase; we see evidence of this from external research like Stack Overflow's Developer Survey (which found 14% of professional developers worked with Go during the past year, a roughly 15% year-over-year increase), as well as analytics for go.dev (which show an 8% rise in visitors year-over-year). Combining this growth with a high satisfaction score is evidence that Go continues to appeal to developers, and suggests that many developers who choose to learn the language feel good about their decision long afterwards. In their own words:
“After 30+ years of development in C, C++, Java, and now seven years of programming in Go, it is still the most productive language by far. It's not perfect (no language is), but it has the best balance of productivity, complexity, and performance.” --- Professional Go developer w/ 5 -- 9 years of experience
“This is currently the best language I know, and I‘ve tried many. The tooling is awesome, compile times are great, and I can be really productive. I’m glad I have Go as a tool, and I don't need to use TypeScript server-side. Thanks.” --- Open source Go developer w/ 3 -- 4 years of experience
As in prior years, the majority of survey respondents told us they work with Go on Linux (63%) and macOS (58%) systems. Small variations in these numbers from year to year are most likely dependent upon who finds and responds to this survey (particularly on the Go blog), as we don't see consistent year-over-year trends in the random sample coming from VS Code.
We do continue to see that newer members of the Go community are more likely to be working with Windows than more experienced Go developers. We interpret this as a signal that Windows-based development is important for onboarding new developers to the Go ecosystem, and is a topic our team hopes to focus on more in 2024.
Respondents continue to be heavily focused on Linux deployments. Given the prevalence of Go for cloud development and containerized workloads, this is not surprising but is still an important confirmation. We found few meaningful differences based on factors such as organization size or experience level; indeed, while novice Go developers appear more likely to develop on Windows, 92% still deploy to Linux systems. Perhaps the most interesting finding from this breakdown is that more experienced Go developers said they deploy to a wider variety of systems (most notably WebAssembly and IoT), though it's unclear if this is because such deployments are challenging for newer Go developers or the result of experienced Go developers using Go in a broader range of contexts. We also observed that both IoT and WebAssembly have steadily increased in recent years, with each rising from 3% in 2021 to 6% and 5% in 2023, respectively.
The computing architecture landscape has changed over the past few years, and we see that reflected in the current architectures Go developers say they work with. While x86-compatible systems still account for the majority of development (89%), ARM64 is also now used by a majority of respondents (56%). This adoption appears to be partly driven by Apple Silicon; macOS developers are now more likely to say they develop for ARM64 than for x86-based architectures (76% vs. 71%). However, Apple hardware isn‘t the only factor driving ARM64 adoption: among respondents who don’t develop on macOS at all, 29% still say they develop for ARM64.
The most common code editors among Go Developer Survey respondents continue to be VS Code (44%) and GoLand (31%). Both of these proportions ticked down slightly from 2023 H1 (46% and 33%, respectively), but remain within this survey‘s margin of error. Among the “Other” category, Helix accounted for the majority of responses. Similar to the results for operating systems above, we don’t believe this represents a meaningful shift in code editor usage, but rather shows some of the variability we expect to see in a community survey such as this. In particular, we exclude the randomly sampled respondents from VS Code for this question, as we know that group is heavily biased towards VS Code. However, that has the side effect of making these results more susceptible to variation each year.
We also looked at respondents' level of satisfaction with Go based on the editor they prefer using. After controlling for length of experience, we found no differences: we don‘t believe people enjoy working with Go more or less based on which code editor they use. That doesn’t necessarily mean all Go editors are equal, but may reflect that people find the editor that is best for their own needs. This would suggest the Go ecosystem has a healthy diversity of different editors geared towards different use cases and developer preferences.
To better understand the web of software and services that Go developers interact with, we asked several questions about tech stacks. We're sharing these results with the community to show which tools and platforms are in common use today, but we believe everyone should consider their own needs and use cases when selecting a tech stack. More plainly: we neither intend for readers to use this data to select components of their tech stack because they are popular, nor to avoid components because they are not commonly used.
First, we can say with confidence that Go is a language for modern cloud-based development. Indeed, 75% of respondents work on Go software that integrates with cloud services. For nearly half of respondents, this involved AWS (48%), and almost one-third used GCP (29%) for their Go development and deployments. For both AWS and GCP, usage is equally balanced among large enterprises and smaller organizations. Microsoft Azure is the only cloud provider that is significantly more likely to be used in large organizations (companies with > 1,000 employees) than smaller shops; other providers show no meaningful differences in usage based on the size of the organization.
Databases are extremely common components of software systems, and we found that 91% of respondents said the Go services they work on use at least one. Most frequently this was PostgreSQL (59%), but with double digits of respondents reporting use of six additional databases, it's safe to say there are not just a couple of standard DBs for Go developers to consider. We again see differences based on organization size, with respondents from smaller organizations more likely to report using PostgreSQL and Redis, while developers from large organizations are somewhat more likely to use a database specific to their cloud provider.
Another common component respondents reported using were caches or key-value stores; 68% of respondents said they work on Go software incorporating at least one of these. Redis was clearly the most common (57%), followed at a distance by etcd (10%) and memcached (7%).
Similar to databases, survey respondents told us they use a range of different observability systems. Prometheus and Grafana were the most commonly cited (both at 43%), but Open Telemetry, Datadog, and Sentry were all in double digits.
Lest anyone wonder “Have we JSON'd all the things?”... yes, yes we have. Nearly every respondent (96%!) said their Go software uses the JSON data format; that‘s about as close to universal as you’ll see with self-reported data. YAML, CSV, and protocol buffers are also all used by roughly half of respondents, and double-digit proportions work with TOML and XML as well.
For authentication and authorization services, we found most respondents are building upon the foundations provided by standards such as JWT and OAuth2. This also appears to be an area where an organization‘s cloud provider’s solution is about as likely to be used as most turn-key alternatives.
Finally, we have a bit of a grab bag of other services that don't neatly fit into the above categories. We found that nearly half of respondents work with gRPC in their Go software (47%). For infrastructure-as-code needs, Terraform was the tool of choice for about ¼ of respondents. Other fairly common technologies used alongside Go included Apache Kafka, ElasticSearch, GraphQL, and RabbitMQ.
We also looked at which technologies tended to be used together. While nothing clearly analogous to the classic LAMP stack emerged from this analysis, we did identify some interesting patterns:
As part of our experimentation with project templates, we wanted to understand how Go developers get started with new projects today. Respondents told us their biggest challenges were choosing an appropriate way to structure their project (54%) and learning how to write idiomatic Go (47%). As two respondents phrased it:
“Finding an appropriate structure and the right abstraction levels for a new project can be quite tedious; looking at high-profile community and enterprise projects for inspiration can be quite confusing as everyone structures their project differently” --- Professional Go developer w/ 5 -- 9 years of Go experience
“It would be great if [Go had a] toolchain to create [a project's] basic structure for web or CLI like `go init <project name>`” --- Professional Go developer w/ 3 -- 4 years of experience
Newer Go developers were even more likely to encounter these challenges: the proportions increased to 59% and 53% for respondents with less than two years of experience with Go, respectively. These are both areas we hope to improve via our gonew prototype: templates can provide new Go developers with well-tested project structures and design patterns, with initial implementations written in idiomatic Go. These survey results have helped our team to keep the purpose of gonew focused on tasks the Go community most struggle with.
A majority of respondents told us they either use templates or copy+paste code from existing projects when starting a new Go project (58%). Among respondents with less than five years of Go experience, this proportion increased to nearly ⅔ (63%). This was an important confirmation that the template-based approach in gonew seems to meet developers where they already are, aligning a common, informal approach with go command-style tooling. This is further supported by the common feature requests for project templates: a majority of respondents requested 1) a pre-configured directory structure to organize their project and 2) sample code for common tasks in the project domain. These results are well-aligned with the challenges developers said they faced in the previous section. The responses to this question also help tease apart the difference between project structure and design patterns, with nearly twice as many respondents saying they want Go project templates to provide the former than the latter.
A majority of respondents told us the ability to make changes to a template and have those changes propagate to projects based on that template was of at least moderate importance. Anecdotally, we haven't spoken with any developers who currently have this functionality with home-grown template approaches, but it suggests this is an interesting avenue for future development.
A perennial topic of discussion among Go developers is potential improvements to error handling. As one respondent summarized:
“Error handling adds too much boilerplate (I know, you probably heard this before)” --- Open source Go developer w/ 1 -- 2 years of experience
But, we also hear from numerous developers that they appreciate Go's approach to error handling:
“Go error handling is simple and effective. As I have backends in Java and C# and exploring Rust and Zig now, I am always pleased to go back to write Go code. And one of the reasons is, believe it or not, error handling. It is really simple, plain and effective. Please leave it that way.” --- Open source Go developer w/ 5 -- 9 years of experience
Rather than ask about specific modifications to error handling in Go, we wanted to better understand developers' higher-level goals and whether Go‘s current approach has proven useful and usable. We found that a majority of respondents appreciate Go’s approach to error handling (55%) and say it helps them know when to check for errors (50%). Both of these outcomes were stronger for respondents with more Go experience, suggesting that either developers grow to appreciate Go‘s approach to error handling over time, or that this is one factor leading developers to eventually leave the Go ecosystem (or at least stop responding to Go-related surveys). Many survey respondents also felt that Go requires a lot of tedious, boilerplate code to check for errors (43%); this remained true regardless of how much prior Go experience respondents had. Interestingly, when respondents said they appreciate Go’s error handling, they were unlikely to say it also results in lots of boilerplate code---our team had a hypothesis that Go developers can both appreciate the language‘s approach to error handling and feel it’s too verbose, but only 14% of respondents agreed with both statements.
Specific issues that respondents cited include challenges knowing which error types to check for (28%), wanting to easily show a stack trace along with the error message (28%), and the ease with which errors can be entirely ignored (19%). About ⅓ of respondents were also interested in adopting concepts from other languages, such as Rust's ? operator (31%).
The Go team has no plans to add exceptions to the language, but since this is anecdotally a common request, we included it as a response choice. Only 1 in 10 respondents said they wished they could use exceptions in Go, and this was inversely related to experience---more veteran Go developers were less likely to be interested in exceptions than respondents newer to the Go community.
The Go team is considering how the unfolding landscape of new ML/AI technologies may impact software development in two distinct veins: 1) how might ML/AI tooling help engineers write better software, and 2) how might Go help engineers bring ML/AI support to their applications and services? Below, we delve into each of these areas.
There‘s little denying we’re in a hype cycle around the possibilities for AI/ML. We wanted to take a step back to focus on the broader challenges developers face and where they think AI might prove useful in their regular work. The answers were a bit surprising, especially given the industry's current focus on coding assistants.
First, we see a few AI use cases that about half of respondents thought could be helpful: generating tests (49%), suggesting best practices in-situ (47%), and catching likely mistakes early in the development process (46%). A unifying theme of these top use cases is that each could help improve the quality and reliability of code an engineer is writing. A fourth use case (help writing documentation) garnered interest from about ⅓ of respondents. The remaining cases comprise a long tail of potentially fruitful ideas, but these are of significantly less general interest than the top four.
When we look at developers' duration of experience with Go, we find that novice respondents are interested in help resolving compiler errors and explaining what a piece of Go code does more than veteran Go developers. These might be areas where AI could help improve the getting started experience for new Gophers; for example, an AI assistant could help explain in natural language what an undocumented block of code does, or suggest common solutions to specific error messages. Conversely, we see no differences between experience levels for topics like “catch common mistakes”---both novice and veteran Go developers say they would appreciate tooling to help with this.
One can squint at this data and see three broad trends:
Taken together, it appears that today, developers are less excited by the prospect of machines doing the fun (e.g., creative, enjoyable, appropriately challenging) parts of software development, but do see value in another set of “eyes” reviewing their code and potentially handling dull or repetitive tasks for them. As one respondent phrased it:
“I'm specifically interested in using AI/ML to improve my productivity with Go. Having a system that is trained in Go best practices, can catch anti-patterns, bugs, generate tests, with a low rate of hallucination, would be killer.” --- Professional Go developer w/ 5 -- 9 years of experience
This survey, however, is just one data point in a quickly-evolving research field, so it's best to keep these results in context.
In addition to looking at how Go developers might benefit from AI/ML-powered tooling, we explored their plans for building AI-powered applications and services (or supporting infrastructure) with Go. We found that we're still early in the adoption curve: most respondents have not yet tried to use Go in these areas, though every topic saw some level of interest from roughly half of respondents. For example, a majority of respondents reported interest in integrating the Go services they work on with LLMs (49%), but only 13% have already done so or are currently evaluating this use case. At the time of this survey, responses gently suggest that developers may be most interested in using Go to call LLMs directly, build the data pipelines needed to power ML/AI systems, and for creating API endpoints other services can call to interact with ML/AI models. As one example, this respondent described the benefits they hoped to gain by using Go in their data pipelines:
“I want to integrate the ETL [extract, transform, and load] part using Go, to keep a consistent, robust, reliable codebase.” --- Professional Go developer w/ 3 -- 4 years of experience
Many developers can relate to the frustrating experience of seeing an error message, thinking they know what it means and how to resolve it, but after hours of fruitless debugging realize it meant something else entirely. One respondent explained their frustration as follows:
“So often the printed complaints wind up having nothing to do with the problem, but it can take an hour before I discover that that‘s the case. The error messages are unnervingly terse, and don’t seem to go out of their way to guess as to what the user might be trying to do or [explain what they're] doing wrong.” --- Professional Go developer w/ 10+ years of experience
We believe the warnings and errors emitted by developer tooling should be brief, understandable, and actionable: the human reading them should be able to accurately understand what went wrong and what they can do to resolve the issue. This is an admittedly high bar to strive for, and with this survey we took some measurements to understand how developers perceive Go's current warning and error messages.
When thinking about the most recent Go error message they worked through, respondents told us there was much room for improvement. Only a small majority understood what the problem was from the error message alone (54%), and even fewer knew what to do next to resolve the issue (41%). It appears a relatively small amount of additional information could meaningfully increase these proportions, as ¼ of respondents said they mostly knew how to fix the problem, but needed to see an example first. Further, with 11% of respondents saying they couldn‘t make sense of the error message, we now have a baseline for current understandability of the Go toolchain’s error messages.
Improvements to Go's toolchain error messages would especially benefit less-experienced Gophers. Respondents with up to two years of experience were less likely than veteran Gophers to say they understood the problem (47% vs. 61%) or knew how to fix it (29% vs. 52%), and were twice as likely to need to search online to fix the issue (21% vs. 9%) or even make sense of what the error meant (15% vs. 7%).
We hope to focus on improving toolchain error messages during 2024. These survey results suggest this is an area of frustration for developers of all experience levels, and will particularly help newer developers get started with Go.
To understand how these messages might be improved, we asked survey respondents an open-ended question: “If you could make a wish and improve one thing about error messages in the Go toolchain, what would you change?”. The responses largely align with our hypothesis that good error messages are both understandable and actionable. The most common response was some form of “Help me understand what led to this error” (36%), 21% of respondents explicitly asked for guidance to fix the problem, and 14% of respondents called out languages such as Rust or Elm as exemplars which strive to do both of these things. In the words of one respondent:
“For compilation errors, Elm or Rust-style output pinpointing exact issue in the source code. Errors should include suggestions to fix them where possible... I think a general policy of ‘optimize error output to be read by humans’ with ‘provide suggestions where possible’ would be very welcome here.” --- Professional Go developer w/ 5 -- 9 years of experience
Understandably, there is a fuzzy conceptual boundary between toolchain error messages and runtime error messages. For example, one of the top requests involved improved stack traces or other approaches to assist debugging runtime crashes (22%). Similarly, a surprising theme in 4% of the feedback was about challenges with getting help from the go command itself. These are great examples of the Go community helping us identify related pain points that weren‘t otherwise on our radar. We started this investigation focused on improving compile-time errors, but one of the core areas Go developers would like to see improved actually relates to run-time errors, while another was about the go command’s help system.
“When an error is thrown, the call stack can be huge and includes a bunch of files I don‘t care about. I just want to know where the problem is in MY code, not the library I’m using, or how the panic was handled.” --- Professional Go developer w/ 1 -- 2 years of experience
“Getting help via `go help run` dumps a wall of text, with links to further readings to find the available command-line flags. Or the fact that it understands `go run --help` but instead of showing the help, it says ‘please run go help run instead’. Just show me list of flags in `go run --help`.” --- Professional Go developer w/ 3 -- 4 years of experience
We commonly hear that developers find Go to be a great fit for microservices, but we have never tried to quantify how many Go developers have adopted this type of service architecture, understand how those services communicate with one another, or the challenges developers encounter when working on them. This year we added a few questions to better understand this space.
A plurality of respondents said they work mostly on microservices (43%), with another ¼ saying they work on a mix of both microservices and monoliths. Only about ⅕ of respondents work mostly on monolithic Go applications. This is one of the few areas where we see differences based on the size of organization respondents work at---large organizations seem more likely to have adopted a microservice architecture than smaller companies. Respondents from large organizations (>1,000 employees) were most likely to say they work on microservices (55%), with only 11% of these respondents working primarily on monoliths.
We see some bifurcation in the number of microservices comprising Go platforms. One group is composed of a handful (2 to 5) of services (40%), while the other consists of larger collections, with a minimum of 10 component services (37%). The number of microservices involved does not appear to be correlated with organization size.
A large majority of respondents use some form of direct response request (e.g., RPC, HTTP, etc.) for microservice communication (72%). A smaller proportion use message queues (14%) or a pub/sub approach (9%); again, we see no differences here based on organization size.
A majority of respondents build microservices in a polyglot of languages, with only about ¼ exclusively using Go. Python is the most common companion language (33%), alongside Node.js (28%) and Java (26%). We again see differences based on organization size, with larger organizations more likely to be integrating Python (43%) and Java (36%) microservices, while smaller organizations are a bit more likely to only use Go (30%). Other languages appeared to be used equally based on organization size.
Overall, respondents told us testing and debugging were their biggest challenge when writing microservice-based applications, followed by operational complexity. Many other challenges occupy the long tail on this graph, though “portability” stands out as a non-issue for most respondents. We interpret this to mean that such services aren‘t intended to be portable (beyond basic containerization); for example, if an organization’s microservices are initially powered by PostgreSQL databases, developers aren't concerned with potentially porting this to an Oracle database in the near future.
Go has a vibrant ecosystem of community-driven modules, and we want to understand the motivations and challenges faced by developers who maintain these modules. We found that about ⅕ of respondents maintain (or used to maintain) an open-source Go module. This was a surprisingly high proportion, and may be biased due to how we share this survey: module maintainers may be more likely to closely follow the Go blog (where this survey is announced) than other Go developers.
Module maintainers appear to be largely self-motivated---they report working on modules that they need for personal (58%) or work (56%) projects, that they do so because they enjoy working on these modules (63%) and being part of the public Go community (44%), and that they learn useful skills from their module maintainership (44%). More external motivations, such as receiving recognition (15%), career advancement (36%), or cash money (20%) are towards the bottom of the list.
Given the forms of intrinsic motivation identified above, it follows that a key challenge for module maintainers is finding time to devote to their module (41%). While this might not seem like an actionable finding in itself (we can‘t give Go developers an extra hour or two each day, right?), it’s a helpful lens through which to view module tooling and development---these tasks are most likely occurring while the developer is already pressed for time, and perhaps it‘s been weeks or months since they last had an opportunity to work on it, so things aren’t fresh in their memory. Thus, aspects like understandable and actionable error messages can be particularly helpful: rather than require someone to once again search for specific go command syntax, perhaps the error output could provide the solution they need right in their terminal.
Most survey respondents reported using Go for their primary job (78%), and a majority (59%) said they use it for personal or open-source projects. In fact, it's common for respondents to use Go for both work and personal/OSS projects, with 43% of respondents saying they use Go in each of these situations.
The majority of respondents have been working with Go for under five years (68%). As we've seen in prior years, people who found this survey via VS Code tended to be less experienced than people who found the survey via other channels.
When we break down where people use Go by their experience level, two findings stand out. First, a majority of respondents from all experience levels said they're using Go professionally; indeed, for people with over two years of experience, the vast majority use Go at work (85% -- 91%). A similar trend exists for open-source development. The second finding is that developers with less Go experience are more likely to be using Go to expand their skill set (38%) or to evaluate it for use at work (13%) than more experienced Go developers. We interpret this to mean that many Gophers initially view Go as part of “upskilling” or expanding their understanding of software development, but that within a year or two, they look to Go as more of a tool for doing than learning.
The most common use cases for Go continue to be API/RPC services (74%) and command line tools (62%). People tell us Go is a great choice for these types of software for several reasons, including its built-in HTTP server and concurrency primitives, ease of cross-compilation, and single-binary deployments.
The intended audience for much of this tooling is in business settings (62%), with 17% of respondents reporting that they develop primarily for more consumer-oriented applications. This isn't surprising given the low use of Go for consumer-focused applications such as desktop, mobile, or gaming, vs. its very high use for backend services, CLI tooling, and cloud development, but it is a useful confirmation of how heavily Go is used in B2B settings.
We also looked for differences based on respondents' level of experience with Go and organization size. More experienced Go developers reported building a wider variety of different things in Go; this trend was consistent across every category of app or service. We did not find any notable differences in what respondents are building based on their organization size.
Respondents were about equally likely to say this was the first time they‘ve responded to the Go Developer Survey vs. saying they had taken this survey before. There is a meaningful difference between people who learned about this survey via the Go blog, where 61% reported taking this survey previously, vs. people who learned about this survey via a notification in VS Code, where only 31% said they’ve previously taken this survey. We don‘t expect people to perfectly recall every survey they’ve responded to on the internet, but this gives us some confidence that we're hearing from a balanced mix of new and repeat respondents with each survey. Further, this tells us our combination of social media posts and random in-editor sampling are both necessary for hearing from a diverse set of Go developers.
Respondents to this survey reported working at a mix of different organizations, from thousand-person-plus enterprises (27%), to midsize businesses (25%) and smaller organizations with < 100 employees (44%). About half of respondents work in the technology industry (50%), a large increase over the next most-common industry---financial services---at 13%.
This is statistically unchanged from the past few Go Developer Surveys---we continue to hear from people in different countries and in organizations of different sizes and industries at consistent rates year after year.
Most survey respondents “self-selected” to take this survey, meaning they found it on the Go blog or other social Go channels. A potential problem with this approach is that people who don't follow these channels are less likely to learn about the survey, and might respond differently than people who do closely follow them. About 40% of respondents were randomly sampled, meaning they responded to the survey after seeing a prompt for it in VS Code (everyone using the VS Code Go plugin between mid-July -- mid-August 2023 had a 10% of receiving this random prompt). This randomly sampled group helps us generalize these findings to the larger community of Go developers.
Throughout this report we use charts of survey responses to provide supporting evidence for our findings. All of these charts use a similar format. The title is the exact question that survey respondents saw. Unless otherwise noted, questions were multiple choice and participants could only select a single response choice; each chart's subtitle will tell the reader if the question allowed multiple response choices or was an open-ended text box instead of a multiple choice question. For charts of open-ended text responses, a Go team member read and manually categorized the responses. Many open-ended questions elicited a wide variety of responses; to keep the chart sizes reasonable, we condensed them to a maximum of the top 10 themes, with additional themes all grouped under “Other”. The percentage labels shown in charts are rounded to the nearest integer (e.g., 1.4% and 0.8% will both be displayed as 1%), but the length of each bar and row ordering are based on the unrounded values.
To help readers understand the weight of evidence underlying each finding, we included error bars showing the 95% confidence interval for responses; narrower bars indicate increased confidence. Sometimes two or more responses have overlapping error bars, which means the relative order of those responses is not statistically meaningful (i.e., the responses are effectively tied). The lower right of each chart shows the number of people whose responses are included in the chart, in the form “n = [number of respondents]”.
We include select quotes from respondents to help clarify many of our findings. These quotes include the length of times the respondent has used Go. If the respondent said they use Go at work, we refer to them as a “professional Go developer”; if they don't use Go at work but do use Go for open-source development, we refer to them as an “open-source Go developer”.
The final question on our survey always asks respondents whether there‘s anything else they’d like to share with us about Go. The most common piece of feedback people provide is “thanks!”, and this year was no different (33%). In terms of requested language improvements, we see a three-way statistical tie between improved expressivity (12%), improved error handling (12%), and improved type safety or reliability (9%). Respondents had a variety of ideas for improving expressivity, with the general trend of this feedback being “Here's a specific thing I write frequently, and I wish it were easier to express this in Go”. The issues with error handling continue to be complaints about the verbosity of this code today, while feedback about type safety most commonly touched on sum types. This type of high-level feedback is extremely useful when the Go team tries to plan focus areas for the coming year, as it tells us general directions in which the community is hoping to steer the ecosystem.
“I know about Go‘s attitude towards simplicity and I appreciate it. I just wish there [were] slightly more features. For me it would be better error handling (not exceptions though), and maybe some common creature comforts like map/reduce/filter and ternary operators. Anything not too obscure that’ll save me some ‘if’ statements.” --- Professional Go developer w/ 1 -- 2 years of experience
“Please keep Go in line with the long term values Go established so long ago — language and library stability. [...] It is an environment I can rely on to not break my code after 2 or 3 years. For that, thank you very much.” --- Professional Go developer w/ 10+ years of experience
That‘s all for this bi-annual iteration of the Go Developer Survey. Thanks to everyone who shared their feedback about Go---we have immense gratitude for taking your time to help shape Go’s future, and we hope you see some of your own feedback reflected in this report. 🩵
