GitHub Actions
Automated testing and deployment triggered by every code change.
GitHub Actions is a CI/CD (Continuous Integration / Continuous Deployment) platform built into GitHub. Every time code is pushed to the repository, Actions can automatically run tests, check code quality, build assets, and deploy to staging or production — without anyone pressing a button.
Think of it as an automated checklist that runs on every code change. Does the new code break any tests? Does it follow code style rules? Is it safe to deploy? Actions answers these questions automatically, before changes reach users.
It's the automated safety net between writing code and shipping it.
Every commit triggers the full test suite. Problems are caught before they reach staging or production, not after they've affected users.
Merge to the main branch and the deploy happens automatically — code style checked, tests passed, server updated. No one forgets a step.
The same steps run the same way every time, regardless of who pushed the code. Human error in the deployment process is eliminated.
GitHub Actions is free for open-source projects and generous with free minutes for private repositories. Automated CI/CD doesn't require a separate paid service.
