Could you build this?
No Building a full Notion clone with block-based editing, nested trees, relational databases, offline-first sync, and real-time CRDT/OT collaboration requires immense low-level state management and distributed systems architecture.
What it would actually take: Requires an offline-first distributed architecture leveraging CRDTs (like Yjs or Automerge) paired with indexedDB on the client and a WebSocket synchronization gateway. The core editor demands a custom or deeply configured block-tree document model (similar to BlockSuite, ProseMirror, or TipTap) combined with an embedded relational engine for database views. This necessitates senior frontend and distributed systems engineers experienced in conflict resolution, memory-efficient DOM virtualization, and local-first data layers.
