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

A fast, free, and modern collection of 100+ developer tools: JSON formatting, encoding, generators, converters, and more. No login required.

My first "vibe coding" experiment: I built a 100% free, client-side PDF engine with zero backend uploads Hey Reddit, I’ve been watching the "vibe coding" trend and decided to run an experiment: building a complete, production-ready web utility entirely through prompt-based AI coding. The result is PDFEngine ( https://pdfengine-neon.vercel.app ). I got tired of online PDF converters that force you to create an account, cap you at 2 files per day behind a paywall, or upload your sensiti

Built a free toolkit that grew into 5 sites, 200+ tools, no signup required I started this a few days ago to build a free invoicing tool for freelancers because everything I found was gated behind a signup wall or a "free trial." It turned into a small portfolio of 5 sites, each aimed at a different kind of solo operator: Ledgerline: invoicing, contracts, and tax calculators for freelancers Rentline: rent increase letters, late fee calculators, and lease guides for landlords Sellerline:
