SSVM
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.
When TensorFlow.js offered a WASM backend, inference performance improved by 10x on CPUs. The WasmEdge runtime enables computer vision models to run on Raspberry Pi devices with sub-10ms inference latency. Cloudflare Workers now serve ML inference requests with zero cold start penalty.
