WASI
A modular set of standardized APIs enabling WebAssembly programs to securely interact with system resources like files and networks.
What is WASI?
WASI (WebAssembly System Interface) is a standardized set of APIs that allows WebAssembly programs to securely interact with system resources such as files, networks, and other operating system features. It solves the problem of WebAssembly being limited to browser environments by providing a portable, secure interface for running WebAssembly anywhere from cloud servers to edge devices. The project is evolving through multiple preview versions, with Preview 2 offering improved modularity, language support, and virtualizability.
WebAssembly runtime developers, cloud infrastructure engineers, and developers building portable applications that need to run WebAssembly outside browser environments.
Developers choose WASI because it provides a standardized, secure way to run WebAssembly anywhere while maintaining strong security guarantees through capability-based access control and offering better language interoperability than previous approaches.
