# Wasmer

A WebAssembly runtime that runs applications and AI agent code in sandboxed environments, with a command-line tool, an embeddable SDK for several languages, and control over file, network and environment access.

Wasmer runs applications in fast, lightweight sandboxes, locally, in the cloud, or in the browser, based on WebAssembly. Users control file, network and environment access for each sandbox, and startup is quick with a small memory footprint. Packages such as Python, JavaScript and Bash run directly from Wasmer's registry through the CLI, which installs on macOS, Linux and Windows.

An embeddable SDK adds the same sandboxing to an application, with packages for JavaScript and TypeScript, Rust, Python, and Swift on iOS and macOS. A sandbox can also be tried directly in the browser without installing anything.
