Open Source Software Development & DevOps Tools
2 open source DevOps and CI/CD tools you can self-host. Compare GitLab, Jenkins, and CircleCI alternatives by pipelines, runners, and license. Updated Sept 2026.
GitLab CE
GitLab Community Edition is an open-source, self-hosted DevOps platform, and an alternative to GitHub and Bitbucket that folds source hosting, code review, CI/CD, and issue tracking into one application. A single install gives teams Git repositories, merge requests, pipelines, a container registry, and project planning without wiring separate services together. The MIT-licensed CE is free to run at any scale.
Gitea
A painless, self-hosted all-in-one software-development service and a lightweight alternative to GitHub and GitLab. Gitea provides Git hosting, code review, issues and pull requests, a package registry, and built-in Actions-compatible CI/CD from a single Go binary that comfortably runs in under 512 MB of RAM.
