## What it is
MediaWiki is a free, open-source wiki software package written in PHP that powers Wikipedia and thousands of other collaborative knowledge sites. It is feature-rich, extensible via hundreds of extensions, localized in over 350 languages, and scalable from small to very large sites.

## Use cases
- run a wiki like wikipedia
- self-host a collaborative documentation site
- build an internal company knowledge base
- set up a multilingual community wiki
- extend a wiki with custom extensions
- migrate an existing wiki to mediawiki

## When to choose
- you need a proven, battle-tested wiki engine for large or small sites
- you want multilingual collaborative editing with version history
- you need a self-hosted knowledge base with a large extension ecosystem
- you want software backed by an active community and long-term support

## When to avoid
- you want a lightweight static site or personal blog
- you need a modern headless CMS with a JavaScript frontend
- you prefer a minimal markdown-based wiki without a database
- your team wants a real-time rich-text collaborative editor out of the box
