I built a free tool that turns SQL schemas into ER diagrams (no signup needed).

Short summary

DevForge is a free, no-signup SQL schema visualizer for Postgres that auto-generates ER diagrams in real time. Built with Next.js, React Flow for rendering, and a custom parser to handle complex schemas including enums, generated columns, and circular foreign keys. Available on Vercel with freemium export options and planned auth and save features.
