Product Overview

MockServer

Description: MockServer is an open source simulator for APIs and services to provide fake responses during testing and development. It allows developers to mock external dependencies for faster testing without requiring real services or networks.

WireMock

Description: WireMock is an open source tool for simulating HTTP-based APIs during development. It enables mocking and stubbing of APIs and servers before they are fully developed to enable faster testing of applications that integrate with them.
