We are building Mockoon, a set of open-source API mocking tools for developers. Created in 2017 by Guillaume Monnet, it has since grown to be used by thousands of developers worldwide. Mockoon is a free and open-source project, and we rely on donations to keep it running and improving. We are also providing consulting and cloud services to help sustain the project.
