GitHub Actions
Automating build, test, and deployment workflows directly within GitHub repositories
GitHub Actions is a continuous integration and continuous delivery platform built into GitHub. Development teams define workflows as YAML files stored in the repository, triggering automated sequences of steps — running tests, building artefacts, scanning for security issues, and deploying to cloud environments — in response to events such as pushes, pull requests, or scheduled timers. Workflows run on GitHub-hosted virtual machines or on self-hosted runners that teams manage themselves. Actions from the GitHub Marketplace allow common tasks to be composed without writing custom scripts. GitHub Actions is now the default CI/CD choice for projects hosted on GitHub, covering everything from open-source libraries to enterprise software pipelines.

- Running automated test suites on every pull request to catch regressions before code is merged into the main branch
- Building and publishing container images or deployment packages when a release tag is created in the repository
- Deploying application updates to cloud environments automatically after tests pass on a target branch
- Scanning code for security vulnerabilities, dependency issues, or quality violations as part of the standard pull request review
- Automating repetitive repository maintenance tasks such as labelling issues, managing stale pull requests, and generating changelogs
