brew install act
Step 2: Run Workflows
act # run push event
act pull_request # run PR event
act -j test # run specific job
act -W .github/workflows/ci.yml # specific workflow
act --secret-file .env.secrets # with secrets
Step 3: Configuration

Guidelines
- First run downloads Docker images (~1-3GB).
- Not all GitHub Actions features work locally (e.g., OIDC tokens).
- Use micro images for faster runs.
- Great for iterating on CI without waiting for GitHub runners.
