Could you build this?

Partial A block-based editor with databases can be assembled from open-source libraries and vibe-coded, but real-time collaboration and a robust database engine are hard to get right.

What it would actually take: A practical stack would use a rich-text framework such as TipTap or ProseMirror, Yjs or Automerge for conflict-free live collaboration, and a Postgres-backed block store with a query layer for database views. The hard parts are reliable sync and conflict resolution across devices, and performance with large documents and databases. Experienced collaborative-editing engineers would make the difference, though a solo builder could reach a usable version over months.
