Hey Product Hunt 👋 I built JWT Decoder & Inspector because debugging auth usually means pasting real tokens into online tools and those tokens often include session data, emails, roles, and org IDs. This one runs 100% client-side. Decode and inspect header, payload, and signature without uploading anything. What it does: Color-coded header / payload / signature Human-readable exp, iat, nbf timestamps Live expired vs valid status Claims reference + one-click copy Strips Bearer automatically Works offline after the page loads It intentionally does not verify signatures — that would mean pasting your signing secret or public key into a web tool. Decode and inspect here; verify on your server. Try it: https://singhajit.com/tools/jwt-... Would love feedback from anyone who lives in auth / API debugging.
