Límits
Requires JavaScript. Extremely large inputs may slow the browser tab. Results depend on your browser APIs; there is no server-side processing quota because nothing is uploaded.
When to use
When you want a quick, free utility without creating an account or sending content to an online converter.
When not to use
When you need server-side integration, batch automation at scale, or certified compliance tooling.
Privacy note
Tool inputs are processed in your browser only. Theme, language and favorites may use localStorage; hosting may keep standard access logs (IP, UA, URL) without tool payloads.

Validate or generate?
Validate JSON against a schema, or infer a draft schema from a sample document.
Which draft?
Follow the schema $schema when present; generated drafts are intentionally simple.
Network $ref?
Remote $ref fetching is not performed—inline or local schemas only.
Privacy?
Documents never leave the browser.
Production schemas?
Treat inferred schemas as starting points; refine types and required fields yourself.
