Mock Dream vs Resource Override

Classic redirector · free Chrome alternative

Resource Override is a long-standing Chrome extension that swaps URLs, injects files and redirects requests.

Where Resource Override wins

Simple URL-to-URL redirects, beloved by frontend devs since forever.

Where Mock Dream wins

Mock Dream actually mocks the response body and headers, not just the URL — and adds a JSON editor, traffic console and CORS handling.
