## What it is
The official Bluesky Social client application for Web, iOS, and Android, built with React Native and TypeScript on top of the AT Protocol. It includes a small Go web service that serves the React Native Web app.

## Use cases
- post and browse a decentralized social media feed
- build a custom client for the AT Protocol / Bluesky network
- self-host or fork a social app on atproto
- integrate Bluesky posting into an app via the app.bsky lexicons

## When to choose
- you want the official Bluesky client experience across web, iOS, and Android
- you want a reference implementation for building AT Protocol apps
- you want to fork a full-featured decentralized social app

## When to avoid
- you need a server implementation like a PDS or AppView (see bluesky-social/pds and atproto repos)
- you need a lightweight API client only - use @atproto/api directly
- you need support for build issues or guaranteed PR reviews
