The Puter team successfully compiled Firefox into WebAssembly, enabling the entire browser to run inside another browser like Chrome. To work around browser network restrictions, all traffic is routed through a WebSocket server using the Wisp protocol while preserving end-to-end encryption. The project relied heavily on AI-assisted compilation and required rapid server scaling to handle unexpected traffic surges.
Background
WebAssembly allows high-performance execution of compiled code directly in browsers, increasingly supporting complex desktop-class applications. Compiling a full browser engine demonstrates significant advances in WASM compatibility, sandboxing, and cross-platform deployment.
