    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!

    Hi HN, I'm opening up the beta for IndigoStack. It's a native macOS app which provides a fresh take on how to run all the services you need for local web development. I've been building it for myself as a Laravel & Drupal developer and I'm now looking to get some beta testers on board! Check it out, and don't forget to sign up to the forums to give us your feedback! https://indigostack.app My motivation: Like many developers I've developed a love-hate relationship with the existing options for local development on a Mac. If they're virtualised, you'll often get... * high CPU usage…
