Designed for developers

Our code has been built to be very easy to understand with a clear cut MVC architecture and an object-oriented architecture.

Time saver

Setup your forum within minutes thanks to Composer. Don't like it? No problem, you can download the archive and you're ready to go!


We have beautiful URLs and more options to get your website on the first page of your favorite search engine. Increase your visibility!


Make sure your users won't miss a thing from your FeatherBB forum. They can access it from any terminal since our theme is reponsive.

Easy to customise

Install a plugin with a single click. Why should you bother to edit the core when it is so simple to customise your forum?

Use it in your native language

We use Gettext and po/mo files to provide you the localisation you need. If your language is not available, all you need to do is open Poedit!
