Comparison
GitHub Actions vs GitLab CI
Two CI/CD systems built into their platforms. The choice is almost always set by where your code lives.
| Aspect | GitHub Actions | GitLab CI/CD |
|---|---|---|
| Configuration | YAML in .github/workflows, many files | One .gitlab-ci.yml, include to split |
| Reusable blocks | Marketplace with thousands of actions | CI/CD Components and templates, a smaller catalog |
| Execution model | Jobs in a workflow, GitHub-hosted or self-hosted runners | Stages and pipelines, GitLab-hosted or self-hosted runners |
| Platform scope | Code, issues, Packages; security depends on the plan | Single DevOps product: registry, environments, security scans, Auto DevOps |
| Self-hosting the platform | GitHub Enterprise Server, paid | GitLab Community Edition is free, Enterprise is paid |
| License | Proprietary service, many actions are open source | GitLab CE under MIT, Enterprise proprietary |
| Free tier | Free minutes for private repos, unlimited for public | Free compute minutes, limits depend on the plan |
| Best for | Open source and teams on GitHub | Teams that want everything in one platform, self-hosted |
Choose GitHub Actions when
- Your code is already on GitHub.
- You want a large catalog of ready actions.
- The project is open source and you want a wide community.
Choose GitLab CI/CD when
- Your code is on GitLab or you need a self-hosted all-in-one.
- Built-in security scans and environments matter.
- Complex pipelines with clear stages.
Bottom line
Pick the CI where your code lives: migrating for the CI alone rarely pays off. Technically both solve typical jobs equally well.
