JWT Token Decode

What it does

Chrome extension for developers to decode and inspect JWTs safely — entirely locally. JWT Token Decode auto-captures tokens from web requests, shows headers, payloads, and claims in a clean, readable view, and helps debug authentication flows without pasting sensitive tokens into online tools.

  Jwt.is – JSON Web Token Debugger2023 · ▲38

  The team at Rownd is excited to announce https://jwt.is, an updated take on JSON Web Token debugging. Like most developers, we've used jwt.io for years, but it lacks a number of useful features that would make it even more convenient. 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!…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
