## Description

Open Watch Party is a free, open source, lightweight browser extension for
watch parties on your favorite services.

Create a room, share the invite code with friends, and watch together while the
extension keeps playback state in sync. When someone plays, pauses, or seeks,
the room follows along in realtime.

Current supported services:
- YouTube
- Netflix

What you get:
- Realtime playback sync for watch parties
- Simple room creation and joining
- Shareable invite codes
- Open source code and public development on GitHub
- Self-hostable backend for people who want to run their own server

Open Watch Party is intentionally small and focused. More services can be added
over time, and contributions are welcome. If you want support for another
streaming service, open an issue or pull request on GitHub:
