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

I built a screenshot API because my personal Puppeteer setup kept breaking. Six months later it has an MCP server and hundereds of users Solo founder here, this is my product, full disclosure. It started as super simple helper self hosted tool for myself: I needed website screenshots for a project, self-hosted Puppeteer, and spent more time babysitting Chromium than building. So I turned the babysitting into a product, because why not. What it does: one GET request in, rendered screenshot
