NeoNema

Fast. Private. Useful.

JWT Decoder

Paste a JSON Web Token to inspect its header and payload. Decoding runs locally — your token is never sent to a server.

Header

        Private by design.
        Decoding happens on your device. NeoNema never sees what you paste. This tool does not
        verify signatures — treat decoded claims as untrusted until your app validates them.
