WasmEdge is a lightweight, high-performance, and extensible WebAssembly runtime for cloud native, edge, and decentralized applications.
It powers serverless apps, embedded functions, microservices, smart contracts, and IoT devices.
Let's get started
1. Install WasmEdge with an one-line command :
curl -sSf https://raw.githubusercontent.com/WasmEdge/WasmEdge/master/utils/install.sh | bash
2. Create an app or function for WasmEdge in:
3. Embed the WasmEdge function into your host app written in:
Compared with Linux containers, WasmEdge could be 100x faster at start-up and 20% faster at runtime.
A WasmEdge app could take 1/100 of the size of a similar Linux container app.
