Binary instruction format that allows code written in multiple languages to run at near-native speed in web browsers and on servers. Like having a universal translator that lets different programming languages run anywhere efficiently.
Game developers use WebAssembly to run complex 3D games in browsers with performance nearly matching native desktop applications.
WebAssembly (Wasm) is an open web standard, not a cloud provider service. All major clouds can run Wasm workloads via containers/VMs/Kubernetes or via third-party runtimes (e.g., Wasmtime, WasmEdge) and platforms (e.g., Fermyon, Cosmonic/wasmCloud).
