This tool: - Runs entirely client-side (your JSON never leaves your browser) - Shows visual side-by-side comparison - Handles nested objects, arrays, and type changes - Generates shareable links (data encoded in URL, no database) - No tracking, no ads, no account required
I use it constantly for comparing API responses during development and debugging config file changes.
The diff algorithm recursively walks both JSON structures and categorizes changes as additions, deletions, or modifications. Performance is decent up to ~10MB files.
The shareable link feature encodes both JSON docs in the URL itself, so you can share comparisons with teammates without any server-side storage.
Open source and completely free. Would appreciate any feedback on the UX or algorithm improvements!
