What is Dev Proxy?

Dev Proxy is an API simulator that helps you effortlessly test your app beyond the happy path. It allows you to:

Test API error handling: See how your app responds to API errors without changing your code
Verify rate limit handling: Simulate API rate limits to improve user experience
Test slow API responses: See how your app handles slow APIs to implement necessary affordances
Create mock APIs: Quickly stand up mock APIs without writing code you won't ship

Dev Proxy works with any type of app and tech stack as it intercepts network requests at the proxy level.
