Sengi runs your GitHub Actions jobs on bare-metal 5 GHz desktop CPUs at $0.003 a minute. Builds finish up to 1.9× faster than on GitHub’s runners, so you save up to 74% a build. You change one line, runs-on, and your coding agent can do it for you.

We run the machines: a fresh VM for every job, cache included. Your build steps, secrets and logs stay in GitHub. Built for Linux CI on Ubuntu 24.04 x64.
