FlowDiagram: Free diagrams your AI can draw. The link is the diagram.

Hi Product Hunt! I'm Tuna, a data architect from India, and I built FlowDiagram because architecture diagrams kept dying as PNGs in wikis. A few things that make it different: - The share link IS the diagram. It's compressed into the URL after the #, so nothing is uploaded and the reader needs no account. - Your AI can draw it without an API key: give Claude Code, Cursor, Copilot or Codex the skill file at flowdiagram.net/flowdiagram.md and describe your system in plain English. - 1,160 vendor logos built in, including every AWS, Azure and GCP service icon. - Real ER modelling that round-trips SQL DDL, DBML and Mermaid, with a live Snowflake import. - Animated data flow, click-to-trace downstream impact, and a present mode on the live canvas. The honest trade-off: no real-time co-editing, since there's no backend. You share links or keep the .flow.json in Git. It's completely free. What's the first system you'd diagram with it? I'd love your feedback.
