[Wasmer](https://wasmer.io/) is a standalone [WebAssembly](https://webassembly.org/) runtime:
* **Universal**: Wasmer is available in *Linux, macOS and Windows* (for both Desktop and [ARM](https://medium.com/wasmer/running-webassembly-on-arm-7d365ed0e50c))
* **Fast**: Wasmer aims to run WebAssembly at near-native speed
* **Pluggable**: Wasmer can be used from almost **any programming language**
* **Safe**: supporting [WASI](https://github.com/WebAssembly/WASI) and [Emscripten](https://emscripten.org/)
It is used to run software fast, universally and safely: standalone applications and universal libraries.
