JWT Token Detective

About

Effortlessly debug JWT authentication flows without digging through network tabs.

As a developer working with JWT-based APIs, I got tired of constantly hunting through Chrome DevTools to find and copy Bearer tokens. 

JWT Token Detective solves this by automatically detecting and organizing all JWT tokens HTTP requests in one clean interface.

  🔍 What it does:
  • Automatically captures JWT tokens from all Bearer Authorization headers
  • Groups identical tokens together (perfect for
  tracking token reuse across API calls)
  • Shows expiration status with clear visual indicators
  • Displays request history for each token with
  timestamps and HTTP methods
  • One-click copy to clipboard for any detected token

  ⚡ Why you'll love it:
  • No more digging through Network tab requests
  • Instantly see which APIs are using which tokens
  • Track token expiration in real-time
  • Clean, organized view of your authentication flows
  • Zero setup required - works automatically

  🔒 Privacy focused:
  • All data stays local in your browser
  • No external network requests
  • Automatic cleanup removes old tokens
  • Only monitors Authorization headers

  Perfect for developers building SPAs, mobile apps, or
  any system using JWT authentication. Simply install,
  browse your authenticated app, and click the extension
  icon to see all detected tokens.

  Note: Requires websites to use standard Bearer token
  authentication in Authorization headers.
