Flarum is a next-generation open-source forum software, designed to be fast, simple, and elegant. Built on PHP and Laravel on the server side and a fluid JavaScript interface on the client side, it offers a modern discussion experience, similar to a social network, without page reloads.

Designed for mobile from the start, Flarum is fully responsive and lightweight. It features real-time discussion threads, mentions, reactions, notifications, a Markdown editor, and integrated search. Its modular architecture relies on a rich ecosystem of extensions that allow adding tags, badges, single sign-on (SSO), anti-spam, and many other features.

On the administration side, Flarum emphasizes moderation and fine-grained permission management by user groups. Open source and actively developed by its community, it constitutes a modern alternative to traditional forums like phpBB, ideal for building an online community on a durable and high-performance technical foundation.
