OneDev

OneDev is the self-hosted GitLab alternative that actually runs on a single server. Git hosting, CI/CD pipelines, issue tracking, Kanban boards, and package registry — all in one Java app. Think "what if GitLab didn't need 16GB of RAM."

If you want a complete DevOps platform you can self-host on a $10 VPS, OneDev is remarkably capable. GitLab is the feature benchmark but demands serious hardware. Gitea is lighter for pure Git hosting but lacks built-in CI. Forgejo is the Gitea fork with more community governance. GitHub is SaaS and free for public repos.

Best for solo developers and small teams who want everything in one self-hosted package without the resource overhead of GitLab.

The catch: the community is small compared to GitLab or Gitea. The CI pipeline syntax is custom — not GitHub Actions or GitLab CI compatible. Java means higher baseline memory than Go-based alternatives. And if you're already on GitHub, the switching cost probably isn't worth it unless self-hosting is a hard requirement.
