JSON diff

Paste two JSON blobs — get a semantic, key-order-independent diff. Adds, removals, value changes, and type changes are tracked separately. Each row has a copyable RFC 6901 JSON Pointer; export the whole diff as an RFC 6902 JSON Patch. Arrays are compared positionally — re-ordered arrays show every shifted index as a change. Runs locally in your browser — neither blob ever leaves the page.
