Mockoon is a full-featured developer tool for API design and mocking. It allows to quickly and easily run mock APIs locally using the desktop application or in headless environments using the CLI. No remote deployment or account is required.

All our tools are free and open-source. We can fund our work on Mockoon thanks to commercial support contracts and sponsorship donations. We use those funds to pay our full-time (@255kb) and some part-time maintainers, as well as infrastructure, etc.

By sponsoring us, you can show your appreciation for all this hard work and also allow us to dedicate more time to this project in the future. For higher sponsor tiers, this is the opportunity to show your brand in front of many developers interested in APIs and automated testing (~35k views per month).

Thank you for considering support!
