## What it is
WatchParty is a self-hostable web application for watching videos together in sync with friends. It synchronizes play, pause, and seek actions across all users in a room and supports screen sharing, YouTube, HTTP video files, magnet links, HLS streams, and a cloud virtual browser, plus text and video chat.

## Use cases
- watch youtube videos in sync with friends
- host a long-distance movie night
- stream a video file to a group with synced playback
- watch videos together with text and video chat
- self-host a watch2gether alternative
- share my screen so others can watch in sync
- stream a torrent magnet link to a watch party

## When to choose
- you want a self-hosted watch-together site with many source types (YouTube, files, magnets, HLS, screen share)
- you need synced playback plus text and video chat in one app
- you want a rabb.it-style shared cloud browser for streaming sites

## When to avoid
- you only need simple peer-to-peer video sync without hosting a server
- you want a fully managed service with no setup or optional API keys
- you need DRM-protected streaming service playback without a virtual browser setup
