Show HN: Free Visual JSON Schema Builder (Generate, Validate and Export)

I built a free JSON Schema Builder that works entirely in the browser — no signup required.

Build JSON schemas visually

Paste JSON and auto-generate schemas with type inference

Export as JSON Schema, TypeScript interfaces, Python classes, etc.

Validate sample data in real time

Why: writing schemas by hand is tedious and error-prone. This tool tries to make the process faster and less painful.

Feedback welcome — I’d love to hear what features would make it more useful in real workflows.
