CI/CD Platform Comparison
Feature-by-feature comparison of the six most widely used CI/CD platforms. Updated March 2026.
| Feature | GitHub Actions | GitLab CI | CircleCI | Bitbucket Pipelines | Azure DevOps | Jenkins |
|---|---|---|---|---|---|---|
| Vendor | Microsoft | GitLab Inc. | CircleCI Inc. | Atlassian | Microsoft | Open Source (CloudBees) |
| Free Minutes / Month | 3,000/month (Team) | 10,000/month (Premium) | 6,000 credits (Performance) | 3,500/month (Premium) | 1,800/month + parallel jobs | Unlimited (your infra) |
| Free Tier | 2,000 mins on Free | 400 mins on Free | 30,000 credits/month | 50 mins on Free | 1 parallel job (public) free | All (self-hosted only) |
| Price per Minute | $0.008 | $0.005 | $0.006 (medium) | $0.005 | $0.004 (with parallel job) | Your infra cost only |
| Max Parallelism | 20 concurrent (Team) | Unlimited (self-managed) | 80 concurrent (Performance) | Up to 100 (paid) | $40/parallel job/month | Unlimited (scale your agents) |
| Ecosystem | Excellent | Good | Good | Strong for Atlassian stack | Excellent for Microsoft stack | Largest plugin library |
| YAML Support | Yes (YAML) | Yes (.gitlab-ci.yml) | Yes (config.yml) | Yes (bitbucket-pipelines.yml) | Yes (azure-pipelines.yml) | Groovy Jenkinsfile (not YAML) |
| Self-Hosted Runners | Yes | Yes (free runners) | Yes (self-hosted runners) | Yes (runners) | Yes (self-hosted agents) | Only (self-hosted) |
| Docker Support | Yes | Yes | Yes (Docker executor) | Yes | Yes | Yes |
| Secrets Management | Built-in | Built-in | Contexts | Repository/workspace variables | Variable groups + Key Vault integration | Credentials plugin |
| Cache Support | Yes | Yes | Yes | Yes | Yes | Yes (plugins) |
| Best For | GitHub repositories, open source projects | Full DevOps lifecycle, enterprise | Fast build pipelines, orbs ecosystem | Jira-Confluence-Bitbucket shops | Microsoft/.NET teams, enterprise | Maximum control, legacy systems |
| Main Weakness | Can get expensive at scale | Steeper learning curve | Pricing complexity | Less powerful outside Atlassian | Complex pricing model | High maintenance overhead |
Best Value for Small Teams
For teams under 20 developers with moderate build volumes, GitHub Actions or Bitbucket Pipelines typically offer the best cost-to-features ratio. GitHub Actions wins on ecosystem breadth; Bitbucket wins if you are on the Atlassian stack.
Best for Enterprise Scale
GitLab CI and Azure DevOps lead for enterprise deployments. GitLab offers a complete DevOps platform with self-managed options. Azure DevOps integrates deeply with the Microsoft ecosystem and benefits from enterprise volume discounts.
Maximum Control
Jenkins remains unmatched for teams that need full pipeline control, custom hardware access, or air-gapped deployments. The trade-off is substantial DevOps overhead. Most teams using Jenkins for new projects are doing so for specific compliance or infrastructure reasons.
