Case Study: Astral achieves up to 4.7x faster CI runs with Depot

Astral makes CI runs up to 4.7x faster with Depot

The customer Astral, a developer of high-performance Python tools like Ruff and uv, faced a critical CI concurrency challenge. When taking stewardship of the python-build-standalone project, its massive 900-job CI matrix threatened to consume their entire GitHub Actions runner limit, halting CI for all other projects. The vendor Depot provided a solution to this scaling problem.

By implementing Depot's GitHub Actions runners, Astral immediately gained the necessary concurrency and performance. The solution made CI runs up to 4.7x faster, with specific results including a 43% reduction in Linux test times and a 20% cost reduction compared to GitHub's larger runners. Depot enabled Astral to maintain its rigorous release schedule and scale its productivity without restructuring workflows.
