Vercel's benjamincanac showcased Avelune, a multiplayer 3D world you can dig up and build on, with proximity voice and an AI NPC ("the Oracle") that reads the live world state. Built with Nuxt, Three.js, TresJS and the AI SDK. Architecture: the whole world is simulated server-side on Vercel at a fixed 20 Hz and streamed over a single WebSocket—browsers predict, the server decides—and each deploy region keeps its own persistent realm. Source code is on GitHub.
