Mockoon Create mock APIs in seconds

What is Mockoon?

Mockoon provides the easiest and quickest method for designing and running mock REST APIs. It operates locally, eliminating the need for remote deployment or account creation, and is available as a free, open-source application. This makes it a suitable choice for environments with high-security requirements or strict privacy regulations, as it functions offline first.

The tool integrates smoothly with existing workflows, including compatibility with the OpenAPI specification. Mockoon enhances API development and testing by offering features like dynamic templating, a rules-matching system, request recording, and proxy capabilities to simulate diverse scenarios effectively. Additionally, Mockoon Cloud offers features for real-time team collaboration, cloud deployment of mock APIs, and AI-powered generation of endpoints and templates to further streamline the development process.

FAQs

What is an "API mock" in Mockoon?

An API mock is a collection of endpoints created in the desktop application to simulate a real API. Each mock can include an unlimited number of endpoints, rules, stateful routes, and more.
Which features are supported in Mockoon Cloud deployments?

Nearly all features available in the desktop application are supported in cloud deployments. Some features may be unavailable due to technical limitations or security reasons. Please refer to the cloud documentation for specific details.
