Mock Dream vs Requestly
Browser request modifier · free Chrome alternative
Requestly is a Chrome/Firefox extension that intercepts requests with rules: redirect, modify headers, replace responses.
Where Requestly wins
Huge feature surface (redirect, replace, headers, scripts, sessions, mock API).
Where Mock Dream wins
Mock Dream focuses on one job — mocking responses — with a faster popup, manga themes and a cleaner traffic console.
