Every time you paste proprietary code into a web-based JSON formatter or regex tester, you’re handing sensitive data to a server that doesn’t need it.

Privacy isn’t an add-on; it’s the defining constraint that separates safe tools from surveillance dressed up as convenience.

Most JWT decoders ask you to trust they’re ‘client-side’ — but trust is not a security property. This decoder uses CSP connect-src ‘none’ to make token exfiltration technically impossible.
