Profile

I built this over the last 6 months from the ground up. Backend is TypeScript with WebSockets (uWebSockets.js). Frontend is plain JS and uses a mix of WebGL + the DOM.RTT is <100ms for US west coast, and around 150-200ms for east coast. The world sim is on a single authoritative server with basic 2D physics. Clients talk to a fleet of horizontally scalable replicas. Replicas are dumb aggregators and never simulate ahead of the primary. Each replica has the full world sim state, and clients connect based on real-world location rather than location in the sim world. There are no handoffs when someone moves through the world. Each replica can handle around 1k clients before the experience start

The company sits in the show hn launch segment, where it competes on its core product or service.

Its current recorded stage is Show HN launch.
