dagger
Automation engine to build, test and ship any codebase. Runs locally, in CI, or directly in the cloud (by dagger)
Shameless plug: solving this "push and pray" problem is something we have been focusing on with Dagger. It's an open-source CI platform that decouples the runtime from the triggers. The runtime is open source and local-first, so you develop the actual logic of your pipelines with a proper devloop. Then, you separately wire up your git triggers. The same pipeline logic can be triggered locally or from git events.
IMO this is the only clean way to solve the problem. If you want to check it out and share feedback: https://dagger.io . We also have a very active Discord server full of CI nerds.

Project mention: Jenkins as a Code, or how I stopped clicking around in the UI | dev.to | 2026-05-18
Side note: if you'd rather not deal with Helm at all, the community also maintains a Jenkins Kubernetes Operator that takes a CRD-first approach. I went with Helm for the simpler upgrade story, but the operator is a perfectly reasonable alternative if you're already heavy into the operator pattern.

Project mention: Node 20 will be deprecated on GitHub Actions runners | news.ycombinator.com | 2025-09-21
Just want to plug https://github.com/ChristopherHX/github-act-runner (not mine)
It's re-implementation of the GHA self-hosted runner in Go for self-hosted runners, based on the popular https://github.com/nektos/act for running GHA locally. Been using this for over a year now and it's been infinitely useful for CI on otherwise unsupported systems (e.g. freeBSD, openBSD in my case).
