JWT Analyzer & Inspector
Extension Delisted
This extension is no longer available in the official store. Delisted on 2025-09-15.
JWT Inspector lets you inspect JSON Web Tokens in requests, cookies and local storage.
Gain control over your JWTs with the JWT Inspector developer tool! Inspect JWTs in requests, cookies, and local/session storage directly on your site. Also, debug any JWT directly from the console or in the built-in UI.
The JWT Inspector allows you to:
• Inspect JWTs in requests, including query strings, headers, and the request body
• Inspect JWTs in cookies
• Inspect JWTs in local and session storage
• Debug JWTs with the built in debugger
• Debug JWTs in console using console.jwt()
All these features are packaged in an intuitive user interface that makes testing JWTs effortless.

Great tool!
Works great, but adds an unnecessary <script> tag to XML responses. Needs some love, but doesn't appear to be under active development. Shame.
Completely breaks PDF loading from the web in Chrome 52 as well as some previous versions. Thought this was a Chrome problem but eventually narrowed it down to this plugin. Without it, everything is fine. With it, many (but inexplicably, not all) PDFs on the internet will not load at all, instead giving a gray screen (although, loading local PDFs always works). This has happened on two different computers. Aside from this issue, the plugin works fine. However, this makes it unusable.
Awesome tool!
Great tool! bye bye copy&paste tokens into jwt.io debugger
I deal with JWTs almost every day - having to go to sites or code to decode or test JWTs is a huge pain. This plugin makes things *so* much easier. Thanks!!!!
It just works! A click of a button and I see the data.
Holy buckets this is helpful. Super simple, but so useful.
Love this thing.
Awesome tool for looking at JWTs in your site =]
I like that I can easily debug without having to leave my current page. It saves time going back and forth. It also automatically pastes jwts once you copy one to your clipboard. Really neat.
Works flawlessly. Exactly what I needed.
So glad that this extension exists!
Debugging JWT's is a PITA, Not anymore. This is such a great plugin and helps me with my development and debugging of JWT's
Hah, this thing is totally amazing. My friend @typerandom is the author, but don't let that fool you: this is a legitimately awesome extension for working with JSON web tokens. It plugs really nicely into the typical Chrome Developer Toolchain, and lets you inspect JWTs on your websites, mess around with your own custom JWTs, and just generally handles everything I need to do when debugging JWT stuff. Huge +1
This makes my debugging workflow a LOT easier.
