Devutils.lol

What it does

Access free, offline developer tools powered by WebAssembly. Process massive fiMost online developer tools are slow, riddled with ads, and secretly upload your sensitive data (like Logs, JWTs, proprietary code, or raw JSON logs) to remote servers. DevUtils is built entirely differently. It is a 100% client-side, offline-capable toolkit powered by WebAssembly and JS Workers. Your data never leaves your device.les securely. 100% client-side with no server uploads, ever.

The fastest ad-free toolkit for developers. Process everything 100% locally. No tracking, no logs, and no data ever leaves your machine. Private and free.

No ads, no tracking, just raw local speed . We handle files as big as your CPU can take— if your system doesn't crash, we won't either . Fast, clean, and free until the end of time . Devutils.lol is designed around the small psychological costs of developer work: privacy doubt, tab-hopping, waiting, sign-ins, and the uneasy feeling that a simple task became a transaction. Open a utility, finish the thought, return to your work with less noise. Format JSON, inspect JWTs, decode payloads, and clean data in the browser so sensitive work does not need a random upload step. No account wall, no pricing modal, no newsletter detour. The interface stays focused on the one job you came to finish.…from devutils.lol

  DevUtils.app – Developer Utilities for macOS2020 · ▲241

  This is a project I've been working on since the start of Covid-19. I built an app so that I don't have to put data into online tools like JWT debugger, JSON formatter, URL decoder, etc... https://devutils.app The app works entirely offline and is open-source. I'm selling the pre-built version of the app to earn some revenue for my time. If you want to try the app but can't afford the price or don't have XCode to build the app, drop me an email (my profile), I'll be happy to provide you a free build. I would love to hear all the feedback/suggestions. Thanks!

  Talanoa▲345

  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…

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
