Real-Time Updates
Plex streams session updates to Tracearr instantly over Server-Sent Events (SSE). Jellyfin and Emby don’t expose SSE on their own, so by default Tracearr detects their sessions by polling on an interval — sessions appear within a poll cycle rather than the moment they start.
The Tracearr SSE plugin closes that gap. Once installed on your Jellyfin or Emby server, sessions push to Tracearr instantly, just like Plex. Without it, Tracearr keeps working through polling.
The plugin is optional. Everything works without it — the plugin only removes the short polling delay for Jellyfin and Emby.
Install the Plugin
In Tracearr, go to Settings → Servers and click Set up real-time updates on a Jellyfin or Emby server card to see these same steps with a copy button for the URL.
Jellyfin
Add the repository
In your Jellyfin dashboard, go to Plugins → Repositories and add a repository named Tracearr with this URL:
https://raw.githubusercontent.com/Tracearr/Media-Server-SSE/main/manifest.jsonInstall from the catalog
Open the Catalog tab and install Tracearr SSE.
Restart Jellyfin
Restart Jellyfin to load the plugin.
Once the plugin is running, Tracearr detects it automatically — no restart of Tracearr needed. The server card in Settings → Servers shows the live connection status, so you can confirm the real-time link is active.
The plugin is open source. You can review or build it yourself at github.com/Tracearr/Media-Server-SSE .
