WABT (The WebAssembly Binary Toolkit) is a suite of C/C++ command-line tools for working with WebAssembly binaries, including wat2wasm, wasm2wat, wasm-objdump, wasm-interp, and wasm2c. It aims for full spec fidelity with 1:1 round-trips between text and binary formats, without optimization features.

Use cases

• convert WebAssembly text format to binary
• disassemble a wasm binary back to wat text
• inspect and dump sections of a wasm binary
• run a wasm module in a standalone interpreter
• compile wasm to C source and header
• validate a WebAssembly binary file
• strip sections from a wasm binary

When to choose

• you need reliable wat<->wasm conversion with spec-compliant round-trips
• you're building a WebAssembly toolchain and need a parser/validator library
• you want to inspect, debug, or run wasm binaries from the command line
• you need to convert wasm to C for embedding

When to avoid

• you need wasm optimization passes - use Binaryen instead
• you need a higher-level compiler target for a new language
• you need a runtime with JIT performance for production workloads
