    Hi HN! I couldn’t find a truly user-friendly PlantUML editor, so I set out to build one. PlantDiagrams lets you describe a diagram in plain English; it generates the PlantUML and renders it instantly. The goal is to shorten the path from idea → diagram without fighting the editor. Tech: - Next.js / Supabase / FLy.io / Vercel Highlights - Natural-language to PlantUML with live preview - Export diagrams (SVG/PNG/TXT) - Organize work with Projects - Share via link; optional comments for review - Sample gallery to open and tweak examples Try it:…

    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…

    Hi HN! I made many small web games in the past with Unity or Phaser. But this time I wanted to make something completely on my own. So I coded a basic game framework in plain JavaScript, and used it to make Almost Pong. This was a really fun project that taught me a lot about JavaScript, and I plan to make more minimalist games with this framework. Interesting fact: Almost Pong doesn't load any assets, all sprites and sounds are generated with code. Happy to answer questions, and please let me know if you have any feedback on the game. Thanks!
