GitHub Actions is a built-in solution for setting up automated workflows - from running tests on every push to deploying code automatically. Steps are declared in YAML, run on Linux, Windows, or macOS, and take advantage of GitHub's hosted runners. This makes it possible to use a single platform for code review, CI/CD, and deployment without external services.
There is a large ecosystem of prebuilt components that automate everything from preparing development environments to handling build artifacts and release flows. Actions can be combined and reused across projects, making it easy to get started, and the community provides many examples and guides.
For larger organizations, features like sharing private workflows, configuring self‑hosted runners, and centralized access control make GitHub Actions a powerful CI/CD tool suitable for both small projects and complex enterprise pipelines.
