Description from store
HTTPMocky is a developer tool that lets you intercept and mock HTTP requests made using fetch or XMLHttpRequest (XHR). Ideal for frontend developers, QA engineers, and anyone working with APIs, this extension helps you simulate server responses directly in the browser.
Features:
Create rules to match XHR or Fetch requests
Override status codes and response bodies
Toggle rules on/off with ease
Manage everything from a custom panel inside Chrome DevTools
How It Works:
HTTPMocky injects lightweight code into the inspected page that wraps the native fetch and XMLHttpRequest objects. It checks each request against your defined rules and returns the mocked response or status when a match is found.
Use Cases:
Test frontend error handling without needing backend changes
Simulate various server responses (e.g. 500 errors, empty payloads, delays)
Develop offline flows or edge cases with ease
