wabt

WABT (pronounced "wabbit") is a suite of tools for WebAssembly, including:

• wat2wasm: translate from WebAssembly text format to the WebAssembly binary format
• wasm2wat: the inverse of wat2wasm, translate from the binary format back to the text format (also known as a .wat)
• wasm-objdump: print information about a wasm binary. Similiar to objdump.
• wasm-interp: decode and run a WebAssembly binary file using a stack-based interpreter
• wat-desugar: parse .wat text form as supported by the spec interpreter (s-expressions, flat syntax, or mixed) and print "canonical" flat format
• wasm2c: convert a WebAssembly binary file to a C source and header.
