Analyze Code
Paste code. Get a visual debug report you can trust.
This is partial understanding by design. It parses JavaScript, extracts supported patterns, and teaches the queue model without executing arbitrary code.
What this helps with
- - Explain known confusing async and Node runtime patterns.
- - Visualize curated scenarios and supported pasted-code patterns.
- - Show likely output order, risks, fix direction, and matching cases.
- - Export notes you can paste into an issue, PR, lesson, or debugging doc.
Clear limits
- - It does not execute arbitrary JavaScript.
- - It does not replace Chrome DevTools, Node inspector, profiling, or tests.
- - It does not perfectly model OS, network, database, or every library behavior.
- - It does not send code to a backend in the current local-first product.
Best way to use it
- - Use Guided Cases when the concept is unfamiliar.
- - Use Analyze Code when you have a small confusing snippet.
- - Use Node Runtime Lab when the issue involves server behavior, streams, fs, crypto, or event-loop pressure.
- - Use Fix Notes when you need to explain the bug to someone else.

This stays local for now. It helps you track where the product still needs sharper cases.
