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. The runtime offers isolation and protection for operating system resources (e.g., file system, sockets, environment variables, processes) and memory space. The most important use case for WasmEdge is to safely execute user-defined or community-contributed code as plug-ins in a software product (e.g., SaaS, software-defined vehicles, edge nodes, or even blockchain nodes).
This is free and open source software.
Key Features
- Run standard WebAssembly bytecode programs compiled from C/C++, Rust, Swift, AssemblyScript, or Kotlin source code.
- Runs JavaScript, including 3rd party ES6, CJS, and NPM modules, in a secure, fast, lightweight, portable, and containerized sandbox.
- Supports mixing of those languages (e.g., to use Rust to implement a JavaScript API), the Fetch API, and Server-side Rendering (SSR) functions on edge servers.
- Supports all standard WebAssembly features and many proposed extensions. It also supports a number of extensions tailored for cloud-native and edge computing uses (e.g., the WasmEdge network sockets, Postgres and MySQL-based database driver, and the WasmEdge AI extension).
