Bearer Buddy – Copy & Decode JWT / Auth Headers

About

This extension makes working with APIs and authenticated web apps easier, Copy Authorization or Bearer headers with one click.

It automatically detects the Authorization header from network requests made by the site you’re currently viewing. With a single click, you can copy the most recent token to your clipboard and reuse it in tools like Postman, curl, or your own scripts.

This saves time when testing or debugging APIs, since you don’t need to manually inspect network requests or re-enter credentials. All sensitive data is encrypted locally and never leaves your browser.

Install this extension if you often work with APIs, need quick access to authentication tokens, or want a safer, faster way to copy and inspect headers directly from your browsing session.

✅ Secure: Fully encrypted and stored locally and only per session, no external data transmission
✅ Zero permissions beyond what is required
✅ Local JWT Decoding: View the header and payload of your JWTs directly in the popup — all processing happens locally, no data is sent anywhere
✅ Decode with jwt.io: Link to decode the token, a clear warning appears before opening JWT to prevent accidental token leaks
✅ Dark mode support
✅ Automatically refresh: when site support refresh tokens, you will see most recent token
