Google Cloud Endpoints vs OpenAPI Specification: What are the differences?

Developers describe Google Cloud Endpoints as "Develop, deploy and manage APIs on any Google Cloud backend". An NGINX-based proxy and distributed architecture give unparalleled performance and scalability. Using an Open API Specification or one of our API frameworks, Cloud Endpoints gives you the tools you need for every phase of API development and provides insight with Google Cloud Monitoring, Cloud Trace, Google Cloud Logging and Cloud Trace. On the other hand, OpenAPI Specification is detailed as "An API description format for REST APIs". It defines a standard, language-agnostic interface to RESTful APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection.

Google Cloud Endpoints and OpenAPI Specification can be categorized as "API" tools.
