The WebAssembly Binary Toolkit — essential tools for inspecting, converting, and validating Wasm binaries.
WABT (WebAssembly Binary Toolkit) is the official suite of command-line tools for working with WebAssembly at the binary level. It includes wat2wasm (text-to-binary), wasm2wat (binary-to-text disassembler), wasm-validate (standards conformance checker), wasm-objdump (binary inspector), and wasm-interp (reference interpreter). WABT is an indispensable debugging tool: when a compiled Wasm module behaves unexpectedly, wasm2wat lets you inspect the actual instructions the compiler emitted.
A Bytecode Alliance CLI and Rust library for parsing, validating, transforming, and composing Wasm components.
The compiler infrastructure library behind wasm-opt — the standard post-compilation optimizer for WebAssembly.
