Visualize, explain, and share database schemas in 3D

What it does

Schema3D solves the 'ERD spaghetti' problem by treating schema visualization as a spatial navigation problem. Explore in 3D instead of scrolling flat diagrams, filter by custom categories to reveal complexity progressively, & share complete schemas via stateless URLs.

It's been a hell of a year with this blowing up, me moving to another country, and switching 2 jobs. In a year we somehow managed to hit 26k stars, grow a 1000+ person discord community, and support 37 languages. I couldn't be more grateful for the community that helped this grow, but now i don't know what direction to take…
