A Bytecode Alliance project providing a CLI and Rust libraries for low-level manipulation of WebAssembly modules. It supports validation, parsing, printing, mutation, stripping, and conversion between WAT/WASM formats, plus WebAssembly component model tooling with WIT interfaces.

Use cases

• validate a wasm binary
• convert wat to wasm and back
• print the text format of a wasm module
• create a component from a core wasm module
• strip custom sections from a wasm file
• inspect wasm binary sections with objdump
• work with WIT interface definitions

When to choose

• you need low-level inspection or manipulation of WebAssembly binaries
• you're building Rust tooling around wasm modules or the component model
• you want to validate wasm files against specific feature flags

When to avoid

• you need a high-level runtime to execute wasm (use wasmtime or wasmer)
• you want a bundler or full build pipeline for web apps
• you need a JavaScript/Node wasm toolchain
