Wasmer enables super lightweight containers based on WebAssembly that can run anywhere: from Desktop to the Cloud and IoT devices, and also embedded in any programming language.

Features

Fast & Safe. Wasmer runs WebAssembly at near-native speed in a fully sandboxed environment.
Pluggable. Wasmer supports different compilation frameworks to best suit your needs (LLVM, Cranelift...).
Universal. You can run Wasmer in any platform (macOS, Linux and Windows) and chipset.
Standards compliant. The runtime passes official WebAssembly test suite supporting WASI and Emscripten.
