Live demos
Each demo runs the complete engine in-memory, in the page: real clients, a real server, and a latency slider standing in for the network.
Contingency
Section titled “Contingency”Contingency is a co-op tower defense game about staged sessions. You draw plans; a scripted commander builds live under them. Each plan is a staged session over the live board, so it turns red when the board moves under it, and a deploy is one atomic commit. Presence carries the pointers and the enemies, and a shared clock moves the enemies on every screen without sending where they are.
Kanban
Section titled “Kanban”Kanban is a board you share with three simulated teammates: a product owner, a developer and QA. It shows the everyday collaboration features: live cursors and drags as presence, card descriptions as Yjs text with everyone’s caret, guarded moves that snap back when two people move one card, and card fields added at runtime as writes to the board’s schema document.
