What Is Fossil?

Fossil is a simple, high-reliability, distributed software configuration management system with these advanced features: 1. Integrated Bug Tracking, Wiki, Forum, and Technotes - In addition to doing [./concepts.wiki | distributed version control] like Git and Mercurial, Fossil also supports [./bugtheory.wiki | bug tracking], [./wikitheory.wiki | wiki], [./forum.wiki | forum], and [./event.wiki | technotes]. 2. Built-in Web Interface - Fossil has a built-in, [https://fossil-scm.org/skins/index.html | themeable], and intuitive [./webui.wiki | web interface] with a rich variety of information pages ([./webpage-ex.md|examples]) promoting situational awareness.

This entire website is just a running instance of Fossil. The pages you see here are all [./wikitheory.wiki | wiki] or [./embeddeddoc.wiki | embedded documentation] or (in the case of the [/uv/download.html|download] page) [./unvers.wiki | unversioned files]. When you clone Fossil from one of its [./selfhost.wiki | self-hosting repositories], you get more than just source code - you get this entire website. 3. Self-Contained - Fossil is a single self-contained stand-alone executable. To install, simply download a [/uv/download.html | precompiled binary] for Linux, Mac, or Windows and put it on your $PATH. [./build.wiki | Easy-to-compile source code] is also available. 4. Simple Networking - No custom protocols or TCP ports. Fossil uses ordinary HTTP (or HTTPS or SSH) for network communications, so it works fine from behind restrictive firewalls, including [./quickstart.wiki#proxy|proxies]. The protocol is [./stats.wiki | bandwidth efficient] to the point that Fossil can be used comfortably over dial-up or over the exceedingly slow Wifi on airliners. 5. CGI/SCGI Enabled - No server is required, but if you want to set one up, Fossil supports four easy [./server.wiki | server configurations]. 6. Autosync - Fossil supports [./concepts.wiki#workflow | "autosync" mode] which helps to keep projects moving forward by reducing the amount of needless [./branching.wiki | forking and merging] often associated with distributed projects. 7. Robust & Reliable - Fossil stores content using an [./fileformat.wiki | enduring file format] in an SQLite database so that transactions are atomic even if interrupted by a power loss or system crash. Automatic [./selfcheck.wiki | self-checks] verify that all aspects of the repository are consistent prior to each commit. 8. Free and Open-Source - Uses the [../COPYRIGHT-BSD2.txt|2-clause BSD license].
