I'm Ramy, maker of Grafloria. I built this engine for my own products first — dashboards, workflow editors, ER diagrams — and kept hitting the same wall every team hits: diagram libraries are free, but diagram editors are where the price tags live. Undo, obstacle-avoiding routing, minimap, exports, real-time collab — that's the "Pro tier" or a $3–12k/dev license almost everywhere. So I open-sourced the whole thing. MIT. No pro tier. Angular, React, Vue, and a plain web component — one engine underneath all four. Two things I'm genuinely proud of: 🧪 Every demo is a CI test. All 104 demo pages run in our pipeline with real mouse gestures — if a demo breaks, the build fails. The docs literally cannot lie. And you can open any demo, hit ‹/› Code, edit the source, and re-run it right in the page. 🧭 The routing. Orthogonal edges that never cross their own nodes — proven by a 480-placement sweep in CI. Most libraries skip this or charge for it. Try it without installing anything: grafloria.com/demos — the n8n-style workflow builder and the dashboard builder are good places to start. I'd love to hear: what's the diagram/canvas feature you've always had to build yourself? That list is literally our roadmap. 🙏
