A Mac app that lets you easily serve up mock JSON, XML, or text responses to make development easier. ServeUp removes the reliance on third party services when developing and testing networking code by allowing you to quickly create custom mock REST API responses and serve content over HTTP or HTTPS. You can set up sophisticated pattern matching using any part of the URL, headers, cookies, form variables, and more, and provide custom responses for each match. You can also provide global overrides for delays and status code responses.
