A blazingly fast JSON serializing and deserializing library for Go, accelerated by JIT and SIMD.

Wasmtime is a standalone WebAssembly runtime from the Bytecode Alliance, built on the Cranelift code generator. It offers fast execution, a security-focused design, configurable resource limits, WASI support and standards compliance, with embedding APIs for Rust, C, C++, Python, .NET, Go and Ruby.

Wago is a pure-Go WebAssembly runtime that compiles Wasm to native machine code without CGO. WASI, the Component Model and other host capabilities are delivered as plugins, and .wasm files can be built into small standalone executables.
