Gitolite: Host Git Repos with Fine-Grained Access Control

Gitolite is an open-source tool that lets you host Git repositories on a central server with per-user, per-repository access permissions. It uses SSH keys for authentication and a simple configuration file to manage access, making it ideal for teams that need granular control without a full DevOps platform. The project has been maintained for over a decade and is widely used in self-hosted setups.
