Overview

Flarum is free, open-source forum software built on Laravel and licensed under MIT. It provides discussions with groups and per-category permissions, moderation and flagging, Markdown or WYSIWYG editing, and in-browser and email notifications. Behaviour is extended through community-built extensions, and installs are self-hosted, upgraded with Composer and PHP CLI commands.

Best for: Teams self-hosting a community forum on their own PHP stack who want extensions and no licence cost
Pricing: No prices are published; the site states Flarum is free forever, MIT licensed and open source.
Runs on: CLI

Strengths and trade-offs

Strengths

Free under the MIT licence, with no paid tiers shown
Hundreds of community-built extensions, plus an API to write your own
Both Markdown and WYSIWYG editors are supported
Groups, per-category permissions, moderation and flagging built in

Trade-offs

Self-hosted: you handle the server, database backups and upgrades
2.0 is still a release candidate, described as ready for early adopters
Support is the community forum; no paid support plan is mentioned
MySQL and MariaDB are distinct drivers, so misconfiguration breaks queries
