Pocket Mocker is a lightweight, zero-config visual debugging tool that lives directly in the browser. It intercepts fetch and XMLHttpRequest via Proxy, providing a floating UI that allows developers to modify API responses, simulate network latency, or trigger HTTP errors on the fly without modifying source code.

While tools like MSW are excellent for automated testing, Pocket Mocker fills a specific gap for rapid UI prototyping and mobile web (H5) debugging. Since it's an embedded NPM package rather than a browser extension, it works in environments where extensions aren't available (like mobile WebViews). It offers a "visual" alternative to code-first mocking libraries.
