  title: Insomnia Mock Server API
  description: >-
    The Insomnia Mock Server API allows developers to create, manage, and
    interact with mock servers powered by Insomnia (Kong). Mock servers
    simulate API endpoints by returning predefined responses based on
    OpenAPI specifications or custom route configurations. This enables
    frontend and backend teams to develop and test against realistic API
    behavior before the actual implementation is complete. Insomnia supports
    both cloud-hosted and self-hosted mock server deployments.
