## What it is
Misskey is an open-source, federated microblogging platform built on the ActivityPub protocol, part of the Fediverse. It is a self-hostable social network server with a rich web UI supporting reactions, timelines, and inter-server communication.

## Use cases
- self-host a federated social media server
- join the fediverse with a Misskey instance
- run a decentralized microblogging community
- federate with Mastodon and other ActivityPub servers
- create a custom social network for a community

## When to choose
- you want a self-hosted, federated alternative to Twitter/X
- you need ActivityPub federation and rich reactions/emoji features
- you want an actively maintained open-source social platform

## When to avoid
- you only need a simple single-user blog
- you cannot operate a Node.js/PostgreSQL server stack
- you need a lightweight static site or minimal resource footprint
