The term, in context
AI-assisted draft · approved dataset
Wasmtime is a standalone WebAssembly runtime, maintained by the Bytecode Alliance, that compiles WebAssembly bytecode to native machine instructions for the host processor using one of several backends — an optimizing compiler, a fast baseline compiler, or a portable bytecode interpreter for platforms without a native backend. Its maintainers work directly on the WebAssembly and Component Model standards it implements.
