JWT Loupe is a free Chrome add-on designed for developers and security professionals who need to inspect JSON Web Tokens (JWTs) efficiently. This tool allows users to decode JWTs directly from the active browser tab or selected text, providing a streamlined approach to understanding token structures and contents. With its intuitive interface, JWT Loupe simplifies the process of JWT inspection by making it accessible with just a few clicks.

One of the standout features of JWT Loupe is its ability to verify signatures locally using JSON Web Key Sets (JWKS), ensuring that users can validate tokens without relying on external services. Additionally, the tool emphasizes user privacy by not collecting any telemetry data, making it a reliable choice for those concerned about data security while working with sensitive tokens.
