I have created 2d Autocad free alternative. Looking for meaningful feedback

It is totally free (and it would be forever) Free AutoCAD Alternative Online — KulmanLab | DXF Editor & Vector Drawing

I built this with a strict set of rules:

• No Accounts / No Registration: You just open the site and start drawing.

• Privacy-First: Your blueprints are yours. They never touch a server; all geometry processing happens entirely client-side. It makes hosting extremely cheap and efficient.

• Offline-First: Using IndexedDB, the app features local autosave. Even if you lose power or close the browser, your files and full granular change history are safely stored in your local browser cache.

• No external libraries, web assembly integration, just pure native canvas and math logic around. I dont like when app feels 'heavy'.

• Precision Snapping: To make drawing accurate enough for manufacturing, I custom-coded a robust snapping engine that locks onto midpoints, centers, intersections, and 45-degree angles.

I would appreciate your feedback to understand what features do you need? what is wrong with UI/UX? Is there any niche for this product?
