Whamm is an open source instrumentation framework that enables developers to debug and monitor WebAssembly applications by injecting code directly into Wasm modules. The tool allows dynamic monitoring and manipulation of running applications, providing observability capabilities for debugging, collecting metrics, and fixing errors in real-time. Installation requires Rust and involves cloning the repository, building from source with Cargo, and adding the binary to your PATH. The framework supports both monitoring program execution and manipulating application behavior dynamically, making it valuable for debugging and updating Wasm applications without static analysis.
