Kiwari WebClient

Self-hosted Roblox web engine —

placeId (optional — leave blank to boot the shell only)

wasm memory pages (64 KiB each — 16384 = 1 GiB)

render scale — 0.5 renders at half resolution (biggest win on weak GPUs)

wasm worker threads — blank/auto caps at cores−1, max 4

Heads up: the engine is a 101 MB wasm binary. The first start reserves up to 1 GiB of shared memory and compiles the module — expect a hard stall of 20–60 s and a large RAM spike. Nothing loads until you press start.
