I found a tool called Next AI that links AI capabilities directly with diagrams. It lets you build and edit diagrams using natural language prompts instead of clicking around the canvas manually. It's a handy way to sketch out architecture when you don't want to drag every box yourself. The project is built on TypeScript with React 19 and Next.js. It supports multiple AI providers and even includes an MCP Server. This means you can use it with the Claude Code CLI to generate diagrams from your terminal. Deployment options are flexible too. You can run the tool locally with Docker or push it to Vercel and Cloudflare Workers. It supports multi provider setups so you can pick the backend that fits your workflow. #Nextjs #AI #Diagrams #TypeScript

Play a free online tile-pattern game with friends or solo against the computer.

A couple weeks ago we were on vacation with friends, and after the kids were asleep we played games -- mostly Qwirkle, which I had never played and am terrible at. I don't care about being terrible at games, so I made a web version to keep playing after vacation: build lines of tiles that share a color or a shape, 2-4 players (or add bots). I wanted it to be low friction, so there are no accounts. Your identity is an anonymous id in localStorage, and you can move it to another device by scanning a QR code or hitting a unique url. Start a game and text someone the link (game slugs are semi-memorable three word phrases), or "Play the computer" and you can play immediately against bots. Games are async-friendly with web push for turn notifications. The stack is one Node process on a small VM, Next.js + Socket.IO, no database. The server and the client use the same engine so moves validate optimistically, and the bots go through the same functions, so bot moves are always legal. State is

Started this week thinking "AI hype is overrated." Ended it shipping my first app — built entirely with Claude, deployed, and live. No CS degree. No team. Just prompts and stubbornness. Try it → What should I build next? #buildinpublic #AI #indiehacker

I built this a year ago, just as a fun experiment, and posted it on my portfolio. It was getting a lot of monthly traffic so I built it as a stand alone app and monetized it. Slowly but surely it’s growing :) Mobile app launches soon too.

做了一个免费的 Concrete Calculator,帮 DIY 用户估算混凝土用量 最近做了一个英文站:The Concrete Calculator 地址: https://the-concrete-calculator.com 它主要解决一个很具体的问题:用户在做 patio 、shed base 、walkway 、slab 这类小型混凝土项目时,不知道该 买多少混凝土、多少袋,或者该订多少 cubic yards 。 目前支持: - Concrete Slab Calculator - Concrete Pad Calculator - Concrete Yard Calculator - Concrete Bag Calculator - waste factor - cubic yards / cubic feet / cubic meters - 简单材料成本估算 做这个站的原因是我发现很多英文混凝土计算器要么广告太重,要么结果不够直观。这个版本尽量把核心计算和 单
