Cloud Endpoints is a new feature introduced by ngrok that provides persistent, always-on endpoints managed centrally via the dashboard and API. These endpoints can handle traffic even if upstream services are offline, solving several problems for ngrok developers such as always on functionality, centralized management, traffic policy configuration, API automation, replacement for Edges, and full integration with other features like Traffic Inspector. Cloud endpoints can be used to create a custom error page when an app is offline, route traffic between internal endpoints, and even automate the process of creating cloud endpoints using the ngrok API. The feature is available on free and pay-as-you-go plans, and documentation is provided for further details.
