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."

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

u/Eleraffa · Reddit
Built a browser-only Markdown editor for my own daily LLM workflows — live DBML schemas, proper DOCX export, token counts Hey r/SideProject , I move a lot of text between LLMs, local docs, and web tools every day. I couldn't find a lightweight browser editor that handled a few specific micro-annoyances without shoving ads in my face, requiring a signup, or routing text through a server. So I vibe-coded Markdown Online (mostly hacked together with Claude) to solve my own itch. It’s a plai

I built NutterTools, a library of useful internet tools.. 🛠️ Hey guys, I have built a new website that hosts a collection of useful image/audio/video/web/AI tools in a neat library. There are probably most websites like this, but this is my attempt at it. It already has 150+ tools and I'm planning to add lots more as I'm posting this. Right now it's hosted via GitHub, if received support, I'll get it onto a new domain and also continue adding more tools to keep the site updated in the future.
