Frequently Asked Questions
Is Toolpilot JWT Decoder really free?
Yes — Toolpilot's JWT Decoder is completely free with no hidden plans, trials, or feature paywalls. All 20 developer tools on Toolpilot are free. The site is supported by minimal display advertising.
Is Toolpilot safer than JWT.io for sensitive data?
Toolpilot's JWT Decoder processes everything in your browser using JavaScript — your data never leaves your device. JWT.io uses client-side js (but auth0 branded), so consider this if you're working with sensitive information.
Does JWT.io send my tokens to Auth0 servers?
JWT.io processes tokens client-side using JavaScript. No token data is sent to Auth0's servers. However, for maximum security with production tokens, Toolpilot's client-side decoder provides the same privacy with no Auth0 association.
Can Toolpilot verify JWT signatures?
Toolpilot's JWT Decoder decodes and displays the header, payload, and signature of any JWT. For signature verification (requiring your secret key or public key), JWT.io supports HS256, RS256, and ES256 verification.
