Fossil is a software configuration management, bug tracking system and wiki software server for use in software development created by D. Richard Hipp.


Fossil is a cross-platform DVCS that runs on Linux, BSD derivatives, Mac and Windows. It is capable of performing distributed version control, bug tracking, wiki services, and blogging. The software has a built-in web interface, which reduces project tracking complexity and promotes situational awareness. A user may simply type "fossil ui" from within any check-out and Fossil automatically opens the user's web browser to display a page giving detailed history and status information on that project. The fossil executable may be run as a standalone HTTP server, as a CGI application, accessed via SSH, or run interactively from the CLI.

Being distributed, Fossil requires no central server, although collaboration is made easier by using one.

Content is stored using a SQLite database so that transactions are atomic even if interrupted by a power loss or system crash.[3]

Fossil is free software released under a BSD license[4] (relicensed from previously GPL).


Fossil is used for version control by the SQLite project, which is itself a component of Fossil. SQLite transitioned to using Fossil for version control over CVS on 2009-08-12.[5][6]

Some examples of other projects using Fossil are:
