Fossil

Fossil is a software configuration management system created by D. Richard Hipp, the author of SQLite. It combines a distributed version control system with an integrated bug tracker, wiki, and built-in web UI. Everything lives in a single SQLite database file, making backups and cloning trivial. You can run Fossil from the command line or use its self-contained web interface for browsing commits and managing issues.

Fossil supports automatic sync via HTTP/HTTPS or SSH, branching and tagging, and has a built-in CGI server that works without Apache. It runs on Linux, macOS, Windows, and any POSIX system. The repository format uses SQLite for storage, so you can query history with SQL directly. Access control and authentication are built in, not bolted on as afterthoughts.

Fossil is ideal for small teams and individuals who want a low-friction alternative to Git hosted on a single server. The SQLite project itself uses Fossil for development. It is released under a BSD license, free for any use, and includes no third-party dependencies beyond a C compiler.
