alt Hacker NewsHow much utilization do you have? For low scale, it's hard to beat GitHub Actions as they offer free runners for public repos and include a bunch of free hours for private repos.
Once you start paying for it, GitHub Actions runners are very expensive. I've used both Jenkins and GitLab before to self-host CI/CD, and you save so much using on-demand (or at higher scale, reserved) cloud instances. I do freelance DevOps work and I've helped clients with these sorts of challenges.
I use it pretty heavily on C++ stuff at GitHub.com/sourcemeta. i.e. take https://github.com/sourcemeta/blaze and this example recent run: https://github.com/sourcemeta/blaze/actions/runs/25751796502.
12 jobs per PR for up to 30 minutes running Linux, macOS, and Windows jobs on LLVM, GCC, and MSVC in static and shared builds with also some sanitiser configurations.
And consider across projects we might send dozens of PRs per week.
Right now it's somehow all fully free on GitHub Actions. I wonder what the same would cost on i.e. CircleCI
