Cached polling (no realtime service) vs Liveblocks

Liveblocks is Cuely's default realtime pick when your description doesn't favor either one: rooms, presence and shared state for collaborative boards and documents, with React hooks. Pick Cached polling (no realtime service) if you care most about viral traffic spikes.
