WasmEdge
Bring cloud-native and serverless application paradigms to Edge Computing with a high-performance WebAssembly runtime.
Overview
WasmEdge is a cutting-edge WebAssembly runtime designed to bridge the gap between cloud-native paradigms and the demands of edge computing. It provides a secure, high-performance, and extensible environment for executing WebAssembly modules, making it suitable for a wide array of modern applications. By leveraging WebAssembly, WasmEdge offers near-native performance while maintaining a strong security sandbox, crucial for distributed and untrusted environments. The tool allows developers to write applications or functions in popular languages like C, Rust, Go, JavaScript, and Python, compile them to WebAssembly, and then run them efficiently. Furthermore, WasmEdge can be embedded into host applications written in languages such as C, Rust, Go, Java, and Python, enabling seamless integration and extension of existing systems. This flexibility makes WasmEdge a powerful choice for building everything from lightweight IoT device logic to robust, scalable microservices and decentralized applications.
