Top Enterprise Open‑Source Tools Every Engineer Should Know

Hello, I'm Bage, sharing practical enterprise open‑source software I use, covering code management, CI/CD, API management, and more.

GitLab

GitLab is an open‑source repository management system using Git. You can use the official hosted service or self‑host it.

Self‑hosting is recommended because the official service can be slow. Besides Git repository, GitLab also provides a container registry and CI/CD tools. I used GitLab for CI/CD, avoiding the need to set up Jenkins.

If you want to learn how GitLab does CI/CD, see the linked article.
