Fossil Version Control System

Fossil is a distributed version control system, bug tracker, and wiki server combined in a single self-contained executable, designed for simplicity and long-term sustainability. Created by Richard Hipp (creator of SQLite) in 2007 for managing SQLite development, Fossil is used by SQLite, Tcl/Tk, and other projects. Key features: single binary under 10MB with no external dependencies, zero installation required, runs on any platform with a C compiler. Integrated version control, bug tracking, wiki, technical notes, and web interface in one tool. Self-hosting using itself for development. All operations are atomic transactions stored in SQLite database ensuring integrity on power failure. Entire project history, wiki, bug reports, and configuration stored in a single SQLite database file for simple backup and transfer. Built-in web server provides repository browsing, timeline view, ticket management, wiki editing, and admin interface. Unified chronological timeline of all changes including commits, ticket changes, and wiki edits. Lightweight branching and merging with merge tracking, conflict resolution, and bisect. Autosync for automatic synchronization between local and remote on commit. Built-in bug and issue tracking with customizable fields, workflow, and SQL-based reporting. Wiki with Markdown and Fossil markup, attached to the repository and version-controlled. Built-in discussion forum and real-time chat. HTTPS and SSH secure access.
