24 alternatives to Jwt.is – JSON Web Token Debugger

We're building on the shoulders of those who've come before us. :-) In addition to the basic JWT decoding and signature verification, we've added things like: - Verification using JWK endpoints - Locally stored history of tokens and keys - Verification for EdDSA signatures - Detection of common token providers (e.g., Google, Apple, etc) - Dark mode!…

If you've done this, you know the drill: you write CSS selectors, the site changes its layout, everything breaks at 2am, and you spend your morning rewriting parsers. LLMs seemed like the obvious fix — just throw the HTML at GPT and ask for JSON.
