I was searching for something like Safari built in local overrides. This tool is perfect for any situation, mock html/js/css files. Mock API responses etc etc Perfect for testing changes on production environments or in other envs where you have no access to the server to update files

Great tool for frontend developers and QA tester for API response, redirects, mock data and much more. Requestly removes the dependency on waiting for backend API's. Really useful to have in your frontend development environment.

App works as expected! Ran into some small issues while creating the rules but the support team was able to help and overcome those
