Comparison

StarSling vs GitHub Actions

GitHub Actions is the default CI for GitHub repositories, and GitHub-hosted runners (ubuntu-latest, ubuntu-24.04) are its standard runner infrastructure. StarSling does not replace GitHub Actions; it runs the same workflows on faster runners and adds an AI layer. You change one line (runs-on), keep every workflow, and StarSling's agents continuously open PRs that optimize caching, dependency installs, parallelization, test sharding, and workflow structure.

FAQ
Is StarSling a drop-in replacement for GitHub Actions runners?

Yes. Change runs-on: ubuntu-latest (or ubuntu-24.04) to runs-on: starsling-ubuntu-24.04. Your workflows, actions, and secrets stay the same.

How is StarSling different from GitHub-hosted runners?

StarSling runs the same workflows on faster hardware and adds AI agents that open optimization PRs. GitHub-hosted runners only execute jobs; they do not optimize your pipeline.
