As developers work with an increasing number of third-party APIs, they need a tool that mocks those APIs for testing purposes without actually firing the API gateway. Mock APIs mirror the behavior of APIs, letting developers test them in a sandbox environment.

WireMock has emerged in recent years as a popular open source tool for API mocking, and last year the project founder Tom Akehurst teamed up with Uri Maoz to launch a company with the same name, based on the open source project. They created a managed cloud service called WireMock Cloud, and today announced a $6.5 million seed investment.
