GitHub Actions generator
Pick your language, triggers, a version matrix and the steps you want — get a valid .github/workflows/ci.yml you can drop straight into your repo. Nothing is uploaded.
These versions run as a parallel matrix. Leave default values to keep it simple.
Custom commands (optional)
Override the default command for a step. Leave blank to use the sensible default.
Save this as .github/workflows/ci.yml in your repository.
Everything runs in your browser. No upload, no sign-up.
How it works
Pick language and triggers
Choose Node, Python, Go, Rust or a generic shell job, then set when it should run — on push, on pull request, and which branch.
Set the matrix and steps
Add the versions to test against and tick the steps you need: install, lint, test, build, cache, upload an artifact or a deploy placeholder.
Copy the YAML
Copy the generated ci.yml or download it, then commit it to .github/workflows/ in your repository. Nothing leaves your device.
