wtf is gitlabhq?

GitLab is a web application that lets you host and manage Git repositories on your own servers instead of relying on a third-party service. Think of it as a self-hosted alternative to platforms like GitHub, you get complete control over where your code lives and who can access it, all without paying per-user fees. The core idea is straightforward: you install GitLab on a server you control, then your team can push code to it, review changes together, and manage who has permission to do what. The application handles all the mechanics of storing Git repositories securely, tracking user accounts, and enforcing access rules. Beyond version control, it includes built-in tools for collaboration, you can comment on specific lines of code, create issues to track bugs or features, propose changes through merge requests (which is GitLab's term for pull requests), and even maintain wiki pages for documentation. Companies and organizations use this when they need code to stay behind their own firewall for security or compliance reasons, or when they want to avoid the ongoing costs of cloud-hosted solutions. A software startup might run GitLab on their own infrastructure to keep proprietary code private, or a large enterprise might choose it because they already manage their own servers and prefer not to depend on external services. The README notes it's used by over 10,000 organizations worldwide. The project is built with Ruby on Rails, a web framework, and is completely open source under the MIT license. Installation requires some technical setup, you'll need to run it on Ubuntu or Debian, along with supporting software like MySQL or PostgreSQL for the database and Redis for caching. The README includes guides for getting it running in production and for developers who want to contribute improvements.
