wasmCloud is a CNCF incubating platform for building, managing, and scaling distributed applications using WebAssembly components. It provides a runtime that manages the lifecycle of WebAssembly actors and capability providers, enabling developers to write portable business logic that connects to infrastructure capabilities like HTTP servers, messaging, key-value stores, and databases through a declarative linking model based on WebAssembly Interface Types (WIT).
