Nebula
Nebula is an infinite canvas where a whole team can sketch at once. The hard part wasn't the rendering — it was making 40 simultaneous editors feel like one shared room. Built on CRDTs over WebRTC with a Postgres snapshot layer, it holds sub-60ms cursor latency across continents and survives going fully offline mid-session.
