wasm-tools is a comprehensive suite of command-line utilities and Rust libraries for working with WebAssembly modules at a low level, providing developers with the ability to inspect, validate, transform, and generate Wasm binaries. It includes a wide range of subcommands that handle tasks such as converting between text and binary formats, validating module structure, and printing human-readable representations of compiled code. The toolkit also supports advanced operations like mutating, shrinking, and generating test cases for WebAssembly modules, making it particularly valuable for testing, debugging, and research purposes. In addition to its CLI, wasm-tools exposes many of its capabilities as reusable Rust libraries, allowing developers to integrate WebAssembly manipulation directly into their applications. The project actively implements and supports evolving WebAssembly proposals, ensuring compatibility with the latest features of the ecosystem.
