JWT Tracker Extension is a free Chrome add-on developed by Dimitry Remenyuk. It falls under the category of Browsers and is specifically listed under Add-ons & Tools. This extension allows users to track and display JWT (JSON Web Token) and SAML (Security Assertion Markup Language) data.

The extension works by tracking any request that contains the "Authorization: Bearer" header, as well as the "SAMLRequest" and "SAMLResponse" form body. It then stores this data temporarily in Chrome's local storage. By default, the extension can store up to 10 requests from different initiators per tab in the Chrome browser.

One of the key features of JWT Tracker Extension is the ability to filter tokens based on their element paths or search for specific values. This allows users to easily find and analyze the desired data.

Overall, JWT Tracker Extension is a useful tool for developers and security professionals who need to track and analyze JWT and SAML data in their Chrome browser. It provides a convenient way to monitor and manage these tokens, enhancing the debugging and testing process.
