Watchstate: Autonomous Media Player Synchronization

Watchstate is an autonomous service designed to synchronize devices with Plex, Jellyfin, and Emby Play media players. The solution allows maintaining a unified playback state without the need for complex integration setup.

A key feature of the project is its independence from third-party external services. This ensures data privacy and reduces reliance on external APIs, which is particularly important for home media server users.

Among the supported platforms:

• Plex
• Jellyfin
• Emby Play

The project is open source on GitHub, where developers publish the source code and installation documentation.
