Fossil

Fossil: a simple, high-reliability, distributed software configuration management system.

Fossil is a distributed version control system (DVCS) designed for simplicity and reliability. It combines version control, a wiki, and a bug tracker in a single, self-contained executable. Developed by D. Richard Hipp (creator of SQLite), Fossil emphasizes a 'single file' approach, storing an entire project's history, wiki, and ticketing in one SQLite database file. This design simplifies deployment, backup, and maintenance, making it ideal for small to medium-sized projects and personal use. Its web interface provides immediate access to project history and collaboration tools, streamlining development workflows.
