GitHub Actions vs GitLab CI 2026: CI/CD Comparison
GitHub Actions vs GitLab CI 2026: hosted CI, runner architecture, pricing, security, marketplace.
GitHub Actions
Hosted CI/CD inside GitHub
- License
- Free + paid
GitLab CI
GitLab's built-in CI/CD pipelines
- License
- Free + paid + EE
GitHub Actions and GitLab CI are the two largest hosted CI/CD systems for repos hosted on each platform. GitHub Actions has more marketplace breadth (10K+ actions); GitLab CI has tighter DevOps platform integration (issue → merge request → pipeline → deploy). Both can drive any test framework — Playwright, Cypress, Selenium, k6 — at scale.

When to pick GitHub Actions
Pick GitHub Actions for code hosted on GitHub, when marketplace breadth matters, when 2K free minutes covers you, or when OIDC integration into AWS/GCP/Azure is critical.
When to pick GitLab CI
Pick GitLab CI when code lives on GitLab, when you want a single DevOps platform (issue tracking → pipelines → deploy), when self-hosted free OSS edition matters, or when DAG pipelines fit your build graph.
Verdict
GHA for GitHub-hosted code + marketplace breadth. GitLab CI for full DevOps platform + Auto DevOps.
