Wasmtime Development

Wasmtime is a standalone, fast, secure WebAssembly runtime from the Bytecode Alliance. It implements the WebAssembly standard and extensions including WASI (WebAssembly System Interface) and the Component Model.

When to Use This Skill

Activate when:

• Compiling Rust or Zig code to WebAssembly targets
• Embedding a WebAssembly runtime in Rust or Elixir applications
• Working with WASI for system interface access
• Using the Component Model and WIT interfaces
• Building plugin systems with WebAssembly sandboxing
• Optimizing wasm module size or runtime performance
