DevTool to mock modify replay delay HTTP response
Speed up your web development process
Replay / modify http response
ModResponse can replay and modify any HTTP response. You can modify API response, insert new JS snippets in your HTML, change the status code, modify HTTP response header, etc.
ModResponse allows you to reroute requests to localhost or your dev domains behind the scene. To the browser, you are still interacting with the production domain, but the request is hitting the host that you have specified instead.
Simulate edge cases
Want to test how your frontend behaves when an API responds slowly? Or when it failed? With ModResponse, you can add delays to request, return an error status code, or simulate different network error condition.
