The zero-dependency WebAssembly runtime for Go — WebAssembly 2.0/3.0 capable, no CGO, with Component Model support.
wazero is a WebAssembly 2.0 and 3.0 capable runtime written entirely in Go with zero external dependencies and no CGO. The 1.12.0 release (May 2026) expands Component Model support, broadening the set of WIT-defined components that can be loaded without translation. wazero provides both an interpreter and a compiler backend, and is designed to be embedded in Go applications without complicating their build toolchain. wazero powers Wasm execution in Open Policy Agent, Trivy, and several other prominent Go projects that need a trustworthy, auditable sandbox.
