GitHub Actions
CI/CD built into GitHub with a huge marketplace
What is GitHub Actions?
GitHub Actions is GitHub's integrated CI/CD platform. Workflows are defined in YAML and run in response to events like pushes, pull requests, and schedules. The marketplace offers 15,000+ pre-built actions for common tasks. For GitHub-hosted repositories, Actions is the path of least resistance for CI/CD. No external service to configure, secrets are managed in repo settings, and the integration with pull requests (status checks, comments) is seamless. The free tier is generous: 2,000 minutes/month for free accounts, 3,000 for Pro. Self-hosted runners allow running on your own infrastructure for heavy workloads. For developers already on GitHub, Actions eliminates the friction of setting up external CI.
