ComfyUI-Model-Analytics

ComfyUI Model Analytics Dashboard

A lightweight, read-only custom node for ComfyUI that helps you figure out which models you actually use and which ones are just wasting disk space.

Why I made this

I kept accumulating gigabytes of checkpoints, LoRAs, and UNets without knowing if they were still tied to any workflow or even loaded recently. This extension scans your setup and gives you a clear dashboard.

What it does

• Disk Scan: Walks through all known model directories on your disk to find files.
• Workflow Parser: Checks your saved workflow JSON files to see which models are referenced.
• Live VRAM Tracking: Hooks into model-loading functions to track what actually gets loaded at runtime, so unrun workflows don't give false positives.
• Recency-Based Categorization: A model counts as "Used" if it was loaded within the last 7 days (configurable in the dashboard). No permanent flags — a model quietly moves back to "Unused" once it's been idle long enough, and comes back the moment it's loaded again.
• Strictly Read-Only: It only analyzes data. No files will ever be deleted or modified automatically.
• Clean Dashboard: Adds a neat button to your ComfyUI menu with tabs for used models, dead weight, and workflow breakdowns.
