FatRat 1.1+ can be further extended by plugins. The up to date source code of plugins can be obtained from the Git repository:
git clone git://git.dolezel.info/PLUGIN_NAME.gitWhen compiling plugins, remember that they need to be installed into the same prefix as FatRat.
Available plugins:
| Plugin name | Dependencies | Description |
| fatrat-subtitlesearch | zlib | Integration with OpenSubtitles.org - easy subtitle searching |
| fatrat-czshare | WITH_CURL in FatRat | Download and upload to CZshare.com |
| fatrat-unpack | libzip for WITH_ZIP | Unpack or pipe RAR (and ZIP optionally) archives inside the application |
FatRat's support for file sharing servers can be extended by Java extensions (in the Git version and future 1.2.x releases).
