Guardian

Decide which devices can stream from your Plex server.

Open source, written in TypeScript.

Why it exists

Plex lets shared users stream from any device, with no way to stop an unknown device before playback starts.

Guardian holds each new device until it is approved. Per-⁠user rules limit schedules, networks and concurrent streams.

Released in September 2025, it has been pulled more than 70,000 times from Docker Hub.
