Application and use cases
Here's how you can use Requestly's Mock Server feature in your daily workflow...
Mock Backend response
When the backend isn't ready and you want to mock the API response.

Mock different Formats
Beside from mocking an API Response, we also allow you to write plain HTML/CSS/JS on our editor and test it out without the hassle of deploying.

Requestly just works :) We are one of the paid users. We have been using Requestly to debug SendX Javascript API on our client's websites and Requestly has saved ton of debugging time for us.

Added a Requestly rule for my entire Github Pages domain so that everything resolves locally and I can import between projects I'm working on without specialized rules. Have I said how much I LOVE @RequestlyIO for dev? Def my most essential tool after a browser & a text editor!
