# StarSling vs GitHub Actions

Last updated: 2026-06-22

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.

## Head to head

| Category | StarSling | GitHub Actions |
|---|---|---|
| Drop-in runner replacement | Yes, swap `ubuntu-latest` for `starsling-ubuntu-24.04`. | N/A. GitHub-hosted runners are the default infrastructure. |
| AI optimization PRs | Yes. AI agents analyze logs/telemetry and open optimization PRs (early access). | No. Runners run jobs; they don't optimize your pipeline. |
| GitHub Actions support | Runs your existing GitHub Actions workflows unchanged. | Native. It is GitHub Actions. |
| Pricing model | Usage-based per-minute; 2,000 free min/mo to start; queue time never billed. | Per-minute for GitHub-hosted runners; included free tier on GitHub plans. |
| Hardware | 5th Gen AMD EPYC; 2-64 vCPU; unlimited concurrency. | Standard shared GitHub-hosted hardware; larger runners available. |

## Best fit

**Choose StarSling if:** Teams already on GitHub Actions who want faster runs and a pipeline that keeps getting faster, with a one-line migration and no workflow rewrites.

**Choose GitHub Actions if:** Teams that want the zero-setup default and are not yet bottlenecked by CI speed or cost.

## 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.
