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!

There are plenty of good tools for load testing such as JMeter, Minigun, and plenty more - but they all have their own set of options to learn. I built this one to support a simpler workflow where you just paste your curl request (or other cli command) after your `spam` config (literally just `spam -r 2 -- curl www.google.com). It's pretty barebones but I'm 100% going to use it in my day to day - figured I'd share it here if it helped anyone else!

In my last project, I was struggling to create and monitor cron jobs. So, instead of creating hundreds of standalone scrips and executing them with cron, I decided to turn those scripts into multiple endpoints. Next, I created a single service that I could schedule HTTP requests to those endpoints and monitor its execution. No more scripts, now everything is endpoints that I can run manually at any time I turned this scheduler service into a Micro-SaaS so you don't have to build it yourself: beew.io I know you can Schedule HTTP requests with Zapier but come on... I will not pay 50 bucks for…

Hi all, this is my latest side project: MockingBot, it's a pure JS/HTML based online iOS mockup tool. It only supports iPhone at now, but iPad will be added soon. http://mockingbot.com we build this tool mainly for UI/UX designers and project managers, but as I'm a developer, so I'm glad to hear your opinions about our product and i'll be very appreciate if you can help answering below question: which prototype tool do you use to mock-up your mobile app? and which feature attract you most? any comments are welcome.

Hi HN, I've been working with LLMs in production for a while both as a solo dev building apps for clients and working at an AI startup. The one thing that always was a pain was to pay OpenAI/Gemini/Anthropic a few dollars a month just for me to say "test" or have a CI runner validate some UI code. So I built this server called ChunkBack, that mocks the popular llm provider's functionality but allows you to type in a deterministic language: `SAY "cheese"` or `TOOLCALL "tool_name" {} "tool response"` I've had to work in some test environments and give good results for experimenting…
