is an open-source API mocking tool. It has an intuitive interface, customizable routes and dynamic responses as well as the ability to automate the creation of mock data sets. Mockoon is compatible with OpenAPI and lets you generate different scenarios that can be tested locally and integrated with a development pipeline. You can also create "partial mocks" by intercepting the requests and only faking the calls that are defined in Mockoon. The partial mocks help simulate specific API routes or endpoints and forward other requests to actual servers. While partial mocks can be useful in certain scenarios, there is a risk of overuse, which may lead to unnecessary complexity. Besides that, Mockoon remains a valuable tool for quickly setting up mock APIs as well as improving and automating development workflows.
