Treebird is a lightweight frontend for Pleroma and Mastodon. It's designed to be simple and comfortable, while supporting all the features you would expect for a pleroma frontend.
Treebird uses FCGI and mastodont-c (versitile library designed for Treebird), so it's not only portable, but incredibly fast as well.
We recently switched from Git to Fossil for development. This allows you to create tickets and edit the wiki. If you want to create tickets / report bugs, please login as an anonymous user, you do not need an account.
