Token Glass

DevTools extension for inspecting and decoding JWTs in real time. Automatically captures tokens from network requests.

Token Glass is a DevTools extension that automatically captures and decodes JWT tokens from your network requests — no copy-pasting required. If you work with APIs that use JWT authentication, you know the pain: copying tokens from request headers, pasting them into jwt.io, scrolling through encoded strings trying to find what you need. Token Glass eliminates that friction entirely. Why install it? See your tokens instantly — every JWT in your network traffic is captured and decoded in real time, right inside DevTools Inspect header, payload, and signature at a glance, without leaving your browser Compare two tokens side by side — paste a second JWT to instantly see what changed between them, with differences highlighted field by field across header and payload Diff tokens from your network history — mark any two captured tokens as A and B to compare them directly, without leaving the Captured view Search across decoded output to quickly find the claim or value you need during debugging sessions Save time every day — whether you're building, testing, or debugging authenticated APIs Built for developers who are tired of juggling tabs just to inspect an auth token.
