Infinite Scaling – Computing in the Browser
summary
Moves heavy server work into the browser using WebAssembly to achieve near infinite scaling by reducing servers to a static file host and shifting CPU work to clients, demonstrated with a video splitter built on ffmpeg running as ffmpeg.wasm ~21 MB and a desktop office renderer that downloads roughly a 90 MB office build example. Uses a virtual FS, ffmpeg.wasm and FileSaver saveAs, streams and instantiates WASM to hide load time. Trade-offs: large download sizes, slower or battery‑limited phones, and never send private data you can’t expose to the client.
