Short answer
BuildJet for GitHub Actions stopped running jobs on March 31, 2026, so the live choice is WarpBuild or Ubicloud. Ubicloud was measured in CI Bench v1: 1.1x faster GitHub-hosted (ubuntu-latest), 83% lower cost per job at 10,000 jobs a month. WarpBuild was not benchmarked (its terms prohibit use to compete with it, and we make a competing runner service), so only its published prices and features are compared. Maintained by Vitko, Inc., which sells one of the products measured.
