Pros and cons
What GitHub Actions does especially well — and the limits to anticipate.
Pros
- Integrated directly into GitHub without external tools.
- Free for public repos and open source projects.
- Rich marketplace of ready-to-use actions.
- Simple YAML configuration at the heart of your repo.
Cons
- Cost can grow with private runner usage.
- Not optimal for very complex pipelines.
- Fewer advanced features than dedicated CI tools.
GitHub Actions: when it makes sense.
GitHub Actions is ideal for GitHub teams; users of other Git forges will choose their native tools.
Keep if
You use GitHub and want integrated CI/CD.. You have open source projects requiring automated tests.
Challenge if
You use another Git platform (GitLab, Gitea).. You have a complex, mature CI/CD infrastructure.
