It can be vibe-coded quickly but can also be done rather quickly without ai - the heavy lifting is UI lib from Zed. That is the real unlock in apps like this.

Small correction: Ferrite uses egui (by Emil Ernerfeldt), not anything from Zed. Different ecosystem entirely.

- Zed uses their own gpui framework - Ferrite uses egui — an immediate-mode GUI library

egui is great for rapid development but has limitations. The v0.3.0 custom editor widget is specifically because egui's built-in TextEdit blocks features like proper multi-cursor and code folding. We're not getting much "for free" there — the Mermaid renderer, syntax highlighting integration, and view synchronization are all custom.

That said, egui definitely accelerated the initial UI work. Credit where due!

You are right, my bad.
