The Mockoon program will assist you in creating server mockups in a convenient interface and easily testing and replicating all types of responses for HTTP and HTTPS protocols. If you are familiar with web development, you'll find this tool useful as an open-source framework that allows testing and replicating all types of HTTP and HTTPS responses. In simpler terms, using a mock server, you can return a so-called mock response when a request meets expectations, check sent requests, as well as forward a request or execute a callback when a request meets expectations.

Key Features of the Program:
Mockoon is a simple yet extremely useful Electron-based application that allows you to create an unlimited number of server mockups or environments with an unlimited number of routes.
You will encounter a pleasant user interface designed in a dark theme, displaying a set of minimal controls.
The WYSIWYG approach, combined with a modern user interface, enables even novice users to take advantage of all the application's benefits.
Among the main advantages of the application are the ability to simultaneously run multiple mock servers and support for all HTTP methods.
It's worth noting that Mockoon allows configuring responses by adding custom headers, regex paths, and multiple types of body content.
The program supports file uploads and automatic mime type detection.
Additionally, the application includes a text editor with auto-save features and simulated delay.

In summary, you have a quite interesting application that should significantly ease the lives of web developers, allowing them to create as many server mockups as they need
