Tools I reach for daily.

JSON Tool

Format, validate, and explore JSON with syntax highlighting. Compare two JSON documents with structural diff using LCS — not just text comparison.

Text Compare

Side-by-side and unified diff viewer for any text — code snippets, log files, config changes. Handles large files via virtual scrolling.

JWT Debugger

Decode and inspect JSON Web Tokens instantly. View header, payload, claims, and expiry. Verify signatures using the jose library — Edge Runtime compatible.
