Free JWT.io Alternative — JWT Decoder & Inspector
JWT.io by Auth0 is the go-to JWT debugger, but it can be slow to load, cluttered with library promotions, and the signature verification UI is confusing. Toolpilot's JWT Decoder gives you a clean, focused interface that instantly decodes any JWT and shows header, payload, claims and expiration — nothing more, nothing less.
