Write WAT, compile to .wasm bytes, call exported functions, download the binary.
libwabt (WebAssembly Binary Toolkit) compiled to WASM itself parses WAT and emits real .wasm bytes. The binary is instantiated in-browser and you can call any function export with comma-separated args.
Write WebAssembly Text format (.wat) and watch it compile to real .wasm bytes you can run in your browser. Call exported functions with form-driven arguments, view the compiled binary as a hex dump, and download the .wasm file. Powered by libwabt (the official WebAssembly Binary Toolkit) compiled to WASM itself.
