• Supports WASI and Emscripten out of the box.
• Fast. Run WebAssembly at near-native speeds.
• Embeddable in multiple programming languages
• Compliant with latest WebAssembly Proposals (SIMD, Reference Types, Threads, ...)

Wasmer CLI ships as a single executable with no dependencies.

curl https://get.wasmer.io -sSfL | sh

Quickstart

You can start by running QuickJS, a small and embeddable Javascript engine compiled as a WebAssembly module (qjs.wasm):

$ wasmer qjs.wasm
QuickJS - Type "\h" for help
qjs > const i = 1 + 2;
qjs > console.log("hello " + i);
hello 3

Here is what you can do next:

• Use Wasmer from your Rust application
• Publish a Wasm package on WAPM
• Read more about Wasmer
