Fauxy

Mock API endpoints instantly. No setup. Just a URL.

What it does

Fauxy lets developers create real, working mock API endpoints in seconds. No servers, no config, no waiting on other teams. Create an endpoint, define a response, and call it immediately from your app. Perfect for frontend development, integration testing, demos, and prototyping. Fauxy is designed to remove friction from building software so you can move faster when real APIs aren’t ready yet.
