## What it is
FluffyChat is an open-source, nonprofit Matrix instant messaging client written in Flutter with a cute, easy-to-use Material You design. It supports end-to-end encryption, group chats, spaces, voice messages, and runs on Android, iOS, web, and desktop.

## Use cases
- chat with friends on the matrix network
- replace whatsapp or telegram with a decentralized messenger
- join public matrix rooms and communities
- send encrypted messages, files, and voice notes
- self-host messaging with a matrix homeserver
- use one messenger across android, ios, and desktop

## When to choose
- you want a user-friendly open-source matrix client
- you need end-to-end encryption with cross-signing and encrypted backups
- you want a cross-platform messenger including a web app
- you prefer a nonprofit, ad-free app compatible with Element, Nheko, and NeoChat

## When to avoid
- you need a client for protocols other than Matrix
- you require fully stable video calling, which is still experimental
- you need a server-side matrix homeserver implementation rather than a client
