<p>
As of Go 1.21, Go's binary toolchain downloads served by <a href="/dl/">go.dev/dl/</a> can be
reproduced and verified by anyone, on any platform,
using <a href="https://pkg.go.dev/golang.org/x/build/cmd/gorebuild">golang.org/x/build/cmd/gorebuild</a>.
For more details, see the blog post
“<a href="/blog/rebuild">Perfectly Reproducible, Verified Go Toolchains</a>.”
</p>

<p>
This page is updated daily with the results of running <code>gorebuild</code> in an Ubuntu VM,
using this script:
</p>

<pre>
apt-get update &&
apt-get -y install software-properties-common &&
add-apt-repository universe &&
apt-get -y install golang-go git msitools &&
go run golang.org/x/build/cmd/gorebuild@latest -p=4
</pre>

<p>
The installation of <code>git</code> enables <code>gorebuild</code>
to fetch Go source code from its canonical Git repository, and
the installation of <code>msitools</code> lets <code>gorebuild</code>
check the contents of the Windows MSI installation file.
The <code>-p=4</code> means to run up to four builds in parallel.
