MoonBit & WebAssembly: Unlocking the True Efficiency of Wasm
summary
MoonBit claims WebAssembly-first code that is both tiny and fast: simple string FFI compiles to 180 bytes, an HTTP component builds to 27 kilobytes, and compilation runs 10 to 100 times faster than Rust in large projects. It actually uses Wasm GC and JS-string-builtins, emits half the Rust size for many binaries, integrates with the Component Model and extism, and demos compile and run (playable Mario, WasmCloud AI agent, in‑browser torch) with live debugging.
