[9] Trac is available on all major operating systems including Windows via Installer or Bitnami,[10] OS X via MacPorts or pkgsrc, Debian,[11] Ubuntu,[12] Arch Linux[13] or FreeBSD,[14] as well as on various cloud hosting services.

Inspired by CVSTrac, Jonas Borgström and Daniel Lundin from Edgewall Software started writing svntrac in August 2003 using SQLite and Subversion.

[18] Trac 0.11, released in June 2008, changed the HTML template system from ClearSilver[19] to Genshi, breaking compatibility with many of the older plugins.

Trac offers a no-frills approach to project management by deeply integrating ticket tracking, version control (for which multiple repositories per environment are supported), and wiki.

[28] Besides the core SVN and Git support, Trac can connect via plugins to many other version control systems, including Bazaar, CVS, Darcs, Mercurial, Monotone, and Perforce.

[citation needed] Features provided by plugins include Continuous integration, account management, tags, spam filtering, blogs and discussion fora, and connectors for XML-RPC and Pastebin.
