WasmEdge is a lightweight, high-performance, and extensible WebAssembly runtime. It is the fastest Wasm VM. WasmEdge is an official sandbox project hosted by the CNCF. LlamaEdge is an application framework built on top of WasmEdge to run GenAI models (e.g., LLM, speech-to-text, text-to-image, and TTS) across GPUs on servers, personal computers, and edge devices. Additional use cases include microservices on the edge cloud, serverless SaaS APIs, embedded functions, smart contracts, and smart devices.

Introduction
The WasmEdge Runtime provides a well-defined execution sandbox for its contained WebAssembly bytecode program. 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). It enables third-party developers, vendors, suppliers, and community members to extend and customize the software product. Learn more here
Performance
Features
WasmEdge can run standard WebAssembly bytecode programs compiled from C/C++, Rust, Swift, AssemblyScript, or Kotlin source code. It runs JavaScript, including 3rd party ES6, CJS, and NPM modules, in a secure, fast, lightweight, portable, and containerized sandbox. It also 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.
WasmEdge 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).

Integrations and management
WasmEdge and its contained wasm program can be started from the CLI as a new process, or from an existing process. If started from an existing process (e.g., from a running Go or Rust program), WasmEdge will simply run inside the process as a function. Currently, WasmEdge is not yet thread-safe. In order to use WasmEdge in your own application or cloud-native frameworks, please refer to the guides below.
