[Resource] An advanced tool for debugging ComfyUI errors

Hey everyone,

I've been using ComfyUI for a while, and like many of you, I spend way too much time staring at red nodes and "RuntimeErrors" instead of actually generating images.

Debugging shouldn't require a CS degree, and pasting logs into ChatGPT doesn't always work because it doesn't know my specific local environment.

So, I decided to build a custom node to fix this workflow bottleneck. I call it ComfyUI Doctor. It’s still a work in progress, but it has saved me a ton of headaches recently, so I wanted to share it with the community to see if it helps anyone else.

What makes this Doctor special?

• It checks your vitals: Before diagnosing, it reads your System Snapshot (Python ver, CUDA, VRAM, pip packages).

• It knows who got sick: It pinpoints the exact Node ID and Node Name that caused the crash.

• It speaks your language: It intercepts the raw Python traceback and uses AI (OpenAI, Gemini, Local Ollama, etc.) to explain the fix in plain English.

Installation: No need to mess with git. It's available now in the ComfyUI Manager. Just search for comfyui-doctor and hit install.

I'd love to hear your feedback or if you run into any edge cases where it fails to diagnose the issue. Let me know what you think!
