Tdarr Autoscale

Automatically scale Tdarr workers based on Plex activity. Reduces workers when people are streaming to prioritize Plex, scales back up when idle.

Features

• Scales workers based on active Plex streams
• Day/Night mode with different worker limits
• Auto-detects Tdarr node ID
• Works with Tautulli OR direct Plex API
• Supports GPU, CPU, or both worker types

Requirements

• Tdarr
• Plex (with Tautulli recommended)
• curl and jq

Installation

1. Download the script
2. Make executable: chmod +x tdarr-autoscale.sh
3. Edit the configuration variables at the top
4. Test: ./tdarr-autoscale.sh
5. Add to cron:

6. Optional - log rotation (clears log weekly):

0 0 * * 0 > /path/to/tdarr-autoscale.log
