description: >-
  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).

    description: >-
      The wasmCloud control interface provides a NATS-based API for managing
      the wasmCloud lattice. It supports operations for starting and stopping
      actors and providers, establishing links between components, querying
      host inventories, and managing application deployments. The wash CLI
      and wasmCloud dashboard interact with hosts through this interface.

    description: >-
      wadm provides a declarative application deployment API for wasmCloud.
      Applications are defined as YAML manifests specifying components,
      capability providers, and their links. wadm manages the desired state
      of applications across the lattice, handling scaling, updates, and
      self-healing through reconciliation loops using the Open Application Model format.

    description: >-
      wash (WAsmcloud SHell) is the comprehensive command-line tool for
      developing, building, deploying, and managing wasmCloud applications and
      WebAssembly components. It bundles a wasmCloud host, NATS server, and wadm
      for local development, and supports publishing components to OCI registries
      and managing remote lattices.

      wasmCloud interfaces are defined using WebAssembly Interface Type (WIT),
      the open standard interface description language maintained as part of the
      W3C WebAssembly Component Model. wasmCloud supports WASI 0.2 interfaces
      as well as wasmCloud-specific interfaces for capability providers covering
      HTTP, messaging, key-value, blobstore, and other infrastructure concerns.

    description: >-
      The wasmCloud Kubernetes Operator enables running wasmCloud infrastructure
      natively on Kubernetes clusters. It deploys wasmCloud hosts as Kubernetes
      workloads and bridges the Kubernetes control plane with the wasmCloud
      lattice, enabling seamless integration with existing Kubernetes tooling
      and GitOps workflows. Defines CRDs for Hosts, Artifacts, Workloads,
      WorkloadDeploments, and WorkloadReplicaSets under the runtime.wasmcloud.dev group.
