Wasmtime: Efficient WebAssembly Runtime

Wasmtime is a powerful standalone runtime designed specifically for WebAssembly (Wasm) and the WebAssembly System Interface (WASI). It operates independently from the web, allowing users to execute WebAssembly code directly on their Windows platform. This utility serves both as a command-line tool and a library for integration into larger applications, making it versatile for developers looking to leverage WebAssembly's capabilities.

The runtime is optimized for performance, utilizing techniques such as ahead-of-time (AOT) compilation and Just-In-Time (JIT) compilation through its Cranelift backend. Wasmtime emphasizes security by providing a sandboxed environment for running untrusted code, ensuring safe execution. Its free license and robust feature set make it an essential tool for developers working with WebAssembly.
