I compiled the Luanti voxel engine to WebAssembly using Emscripten. It supports peer-to-peer gaming through a proxy and runs fully in the browser (except Safari). Tonight at 8pm german time, I'm stress-testing it with a "Game Night" event using VoxeLibre.

No installs required. Fully open-source stack.
