Free private workflow JSON first-aid scanner

I made a small client-side scanner for the first pass on ComfyUI workflow JSON files:

Try it: https://kevin88vvv-droid.github.io/comfyui-workflow-troubleshooting-checklist/

It currently:

• recognizes UI workflow and API prompt JSON formats;
• inventories node types and model filename references;
• flags common macOS, Linux, and Windows absolute paths;
• flags likely credential patterns without displaying their values;
• runs entirely in the browser, with no upload or account.

The source and a longer troubleshooting checklist are here:

This is intentionally a heuristic preflight, not a replacement for running the graph. It cannot validate Python dependencies, execute nodes, prove licensing, or guarantee portability. Keeping the first failing node and complete terminal error is still the most useful next step.

Feedback and representative non-sensitive workflow examples are welcome, especially for node formats or model references the scanner misses.
