wazero

wazero is a zero-dependency WebAssembly runtime written in Go that enables developers to execute WebAssembly modules directly within Go applications without relying on external toolchains or CGO. It fully implements the WebAssembly core specification and supports both interpreter and compiler execution modes, allowing developers to choose between portability and performance. One of its defining characteristics is its pure Go implementation, which simplifies cross-compilation and deployment across different platforms. Wazero is designed to securely run code compiled from other languages, leveraging WebAssembly’s sandboxing model to isolate execution and reduce risk. It is particularly useful for embedding plugins, extending applications, or running untrusted code in a controlled environment. The runtime also provides flexible configuration options and integrates seamlessly into Go-based systems, making it a powerful tool for modern backend and systems development.
