## What it is
Symphony (Sym) is a modern open-source community platform written in Java that combines forum, Q&A, BBS, social network, and blog functionality. It features real-time interactions, Markdown rendering, SEO optimization, moderation tools, and an admin dashboard, deployable via Docker.

## Use cases
- self-host a community forum in Java
- build a Q&A site like Stack Overflow
- run a BBS discussion board
- create a social network community site
- host a team knowledge-sharing community
- launch a blog plus forum hybrid platform

## When to choose
- you need a full-featured Java-based community/forum system
- you want real-time replies, notifications, and moderation out of the box
- you want SEO-friendly Markdown-rendered discussions
- you prefer Docker deployment with multiple built-in themes

## When to avoid
- you need a lightweight forum for a small site
- your stack is PHP/Node and you prefer Discourse/Flarum-style tools
- you are a business without a commercial license (community edition restricts commercial use)
- you need multi-node clustering without purchasing the commercial edition
