WebAssembly Toolchains

Comprehensive development toolchains to compile, optimize, and run native WebAssembly binaries.

Compiler Workflow

Compilers

WebAssembly supports a wide range of compilers including LLVM (Clang), Emscripten, and Rust's wasm32 target. These tools translate native code into the .wasm binary format.

LLVM: Compile C/C++ to WebAssembly
Emscripten: HTML5 with JavaScript & WebAssembly
WASI: WebAssembly System Interface standard
Wasmtime: Standalone WebAssembly execution

Language Ecosystem

Rust

Rust is the most popular language for WebAssembly development with excellent tooling integration via rustc, cargo-wasm, and wasm-pack.

C/C++

Native C/C++ developers can use LLVM-based toolchains to compile legacy or performance-critical code to WebAssembly with full compatibility.
