Show HN: I made a JSFiddle-style playground to test and share prompts fast https://ift.tt/3rKndSB

Show HN: I made a JSFiddle-style playground to test and share prompts fast I built this out of frustration as I lead the development of AI features at Yola.com. Prompt testing should be simple and straightforward. All I wanted was a simple way to test prompts with variables and jinja2 templates across different models, ideally somthing I could open during a call, run few tests, and share results with my team. But every tool I tried hit me with a clunky UI, required login and API keys, or forced a lengthy setup process. And that's not all. Then came the pricing. The last quote I got for one of the tools on the market was $6,000/year for a team of 16 people in a use-it-or-loose-it way. For a tool we use maybe 2–3 times per sprint. That’s just ridiculous! IMO, it should be something more like JSFiddle. A simple prompt playground that does not require you to signup, does not require API keys, and let's experiment instantly, i.e. you just enter a browser URL and start working. Like JSFiddle has. And mainly, something that costs me nothing if I'm or my team is not using it. Eventually I gave up looking for solution and decided to build it by myself. Here it is: https://langfa.st Help me find what's wrong or missing or does not work from you perspctive. P.S. I did not put any limits or restrictions yet, so test it wisely. Don't make me broke, please. https://langfa.st/ July 12, 2025 at 11:11PM

Show HN: I Built a Stick-On Wireless Lamp That Installs in 30 Seconds https://ift.tt/sQmbnUV

Show HN: I Built a Stick-On Wireless Lamp That Installs in 30 Seconds Hi HN! I recently built a simple, rechargeable wall lamp that doesn't require any tools, wires, or drilling. It sticks to surfaces using adhesive pads, rotates 360°, and charges via USB-C. The goal was to make lighting *super minimal, renter-friendly, and easy to install*. The idea came from personal frustration — I live in a rented apartment where I can’t drill holes, and I wanted a modern-looking light I could reposition easily. I know this isn’t a software product, but I figured some of you might appreciate the problem-solving side of it — designing minimal hardware that’s useful, elegant, and simple. Would love feedback on the product or the landing page: Happy to answer any questions about the design, battery, lighting specs, remote control logic, etc. Thanks! https://ift.tt/VidWoOU July 13, 2025 at 01:56AM
