GitLab CI vs GitHub Actions
Comparing two leading cloud-native CI/CD platforms for modern DevOps teams.
Overview
What is being compared
GitLab CI/CD lives inside the GitLab DevOps platform, which covers the whole lifecycle from planning to monitoring. GitHub Actions lives inside GitHub, the dominant code host. Both use YAML, support self-hosted runners and have component ecosystems, so the choice usually follows where the code is hosted.
- Home platform — GitLab, a full DevOps platform — GitHub
- Scope — Planning through monitoring in one product — CI/CD integrated with the GitHub ecosystem
- Configuration — YAML — YAML
- Runners — Hosted or self-hosted — Hosted or self-hosted
- Reuse — CI/CD Components, include templates — Marketplace, reusable workflows
How each pipeline is structured
GitLab runs jobs in stages, all jobs of a stage in parallel. GitHub Actions links jobs with needs, which gives finer control over the dependency graph.
What comes in the box
Green is part of the platform; yellow needs a higher tier, a separate license or your own operation.
