Show HN: Jwt.is – JSON Web Token Debugger

Thanks!

Yeah, the GPT stuff was just a fun easter egg. :-D

also https://jwt.ms (fully client side, hosted by Microsoft)

Hey thanks for the feedback! We added a note under the encoded section to address this - do you think that helps?

> This lets me wait 10 seconds to let GPT tell the definitions for each part of the JWT, which don't change.

Yeah, that's lost on me. Why not embed it as a string? Seems quite lazy, as the current solution would presumably eat up all their OpenGPT credits.

That, and I would have preferred an explainer from someone who understands JWT. Another obvious disadvantage of using AI is that the response can change over time, so it has the potential to hallucinate.

> This is like an afternoon of work, and it's more or less a carbon copy of the existing tools. No one will care about any of the features you are describing. How much time do you think people spend on debugging JWTs?

This seems a bit dismissive, though. Let's see how many people use it before making broad judgements like that. It comes across as rude and unnecessary.

It's definitely more than an afternoon of work, though I can understand how you might think that. Things are often harder and more complex than we realize at first. :-)

One of the biggest gaps with the current implementation is lack of support for JWKs. We wanted to support that. Also, dark mode. It's the little things.

For the record, no tokens are ever sent anywhere. Everything stays local to the browser. If you hit the "GPT" button, it just transmits the payload--nothing else. That part is definitely a fun experiment. It's more "useful" with more complex payloads. But it may not stick around long-term. We'll see.

The website was probably created as a subtle way to promote their startup.

Yes, it certainly could be; however, it would be up to the maintainers of that project whether to accept contributions. "Competition" is good for everyone though. Maybe they'll adopt some of our ideas. :-D

Sorry about that--always a few bugs in the first rev. It's working now!

Thanks! We have a few improvements to make around copy/paste stuff, array printing, etc. Thanks for the feedback!
