About:
WABT (WebAssembly Binary Toolkit) is a suite of utilities for converting, analyzing, and manipulating WebAssembly (Wasm) binaries. It provides essential tools like wasm2wat for converting binary format to text format and wat2wasm for the reverse operation. This toolkit is invaluable for developers working directly with WebAssembly who need to inspect, debug, or optimize their code.

Key Features:

wat2wasm: Convert WebAssembly text format to binary
wasm2wat: Convert WebAssembly binary to text format
wasm-objdump: Disassemble and inspect Wasm modules
wasm-validate: Validate Wasm binary structure
Cross-platform support

Use Cases:

Debugging WebAssembly binaries by converting to human-readable text
Optimizing Wasm file sizes for web deployment
Inspecting compiled output from languages like Rust or C++ targeting Wasm
Validating Wasm modules for correctness

Alternatives:

Binaryen – Focuses more on optimization and code generation, while WABT excels at format conversion and inspection
Emscripten – Primarily a compiler toolchain, whereas WABT is a binary manipulation toolkit
