Overview
Manga-styled HTTP mocker. Intercept fetch/XHR with rules — black & white, no fluff.
Mock Dream is a developer tool that intercepts fetch() and XMLHttpRequest calls on the page you are testing and replaces the response with a payload you defined. Build UI without waiting for the backend, reproduce edge cases (500s, slow responses, empty arrays), and demo flows offline. WHAT IT DOES • Intercept fetch & XHR via rules (URL pattern + method) • Return custom JSON, status codes, headers, latency • Live traffic log: see every request, mocked or pass-through • "Mock this" — turn any real request into a rule with one click • Import / export rule sets as JSON — share with your team • Detached window mode (resizeable) + anchored 800x600 popup • Per-tab badge counter, on/off master switch, undo/redo WHAT IT DOES NOT DO • No tracking, no analytics, no remote code • No account, no login, no cloud sync • Does not read or transmit page content anywhere • Works 100% locally — your rules live in chrome.storage.local PRIVACY Mock Dream does not collect, transmit, or sell any user data. All rules and traffic logs stay on your machine. Full policy: https://mock-dream.lovable.app/privacy OPEN ABOUT BROAD HOST ACCESS The extension needs <all_urls> because developers test against any domain (localhost, staging, production debugging). It only acts on URLs that match a rule you wrote. No background scraping.
