Tool Breakdown
GitHub Actions
Zero-config for any team already hosting on GitHub, the largest action marketplace, and free unlimited runs on public repositories make it the default choice for most teams.
- Triggers directly from GitHub events (push, PR, release) with no separate integration to configure
- Largest CI/CD marketplace (17,000+ actions) covering nearly every common build, test, and deploy step
- Public repositories run entirely free with unlimited minutes on standard runners
- Private-repo Free plan is capped at 2,000 minutes/mo before usage-based billing kicks in
- A new $0.002/min platform charge applies to self-hosted runners on private repos starting March 2026
- No built-in security scanning depth comparable to GitLab Ultimate — relies on third-party marketplace actions
GitLab CI/CD
Built-in CI/CD for GitLab's all-in-one DevOps platform, available as a self-hostable Community Edition or as GitLab.com SaaS, with integrated security scanning on paid tiers.
- Community Edition is open source (MIT License) and free to self-host forever with no user limits
- Ultimate tier bundles SAST, DAST, and dependency scanning that runs automatically and reports inline on merge requests
- One platform for source control, CI/CD, and container registry — no third-party integrations to wire up
- Premium ($29/user/mo) and Ultimate ($99/user/mo) are billed annually only, with no monthly option
- Free tier is capped at 400 CI/CD compute minutes/mo, well below GitHub Actions' public-repo allowance
- Self-hosting the full platform (not just CI) requires more operational overhead than a CI-only tool
Frequently Asked Questions
Is GitHub Actions cheaper than GitLab CI? +
For small teams, GitHub Actions is usually cheaper: public repos run free and unlimited, and the private-repo Free plan includes 2,000 minutes/mo at no cost. GitLab's Free tier caps out at 400 CI/CD minutes/mo, and its paid tiers are priced per user per month rather than by compute minutes, so costs scale differently as your team grows.
Can I self-host GitLab CI for free? +
Yes. GitLab Community Edition is open source under the MIT License and can be self-hosted indefinitely with no user limits or feature restrictions on CE. GitHub Actions has no equivalent fully self-hosted, license-free option — it's a feature of GitHub.com or GitHub Enterprise Server.
Which tool has better security scanning built in? +
GitLab's Ultimate tier includes comprehensive SAST, DAST, and dependency scanning that runs automatically in the pipeline and surfaces results directly in merge requests. GitHub Actions can achieve similar results through marketplace actions (e.g., CodeQL, Dependabot) but the scanning isn't as tightly unified into one paid tier.
