We have always believed in showing rather than telling, which is the philosophy behind the benchmarks on our landing page. We benchmark real-world open-source projects, building them with both
depot build and
docker build in GitHub Actions, for every upstream commit. And the benchmarks themselves are open source, you can click on any of them and see the side-by-side comparison of every run.
Mastodon is a free, open-source social network server based on ActivityPub, where users can follow friends and discover new ones. They have been building multi-platform images in GitHub Actions, with 3-hour build times.
We set up a benchmark using Depot and the results shattered our existing records. We built Mastodon's multi-platform image 53x faster than building it in GitHub Actions with Docker. We hope to contribute this back upstream to Mastodon in the weeks ahead.
