Mock Dream — Mock API, Intercept & Modify HTTP Requests Edge extension security report

Mock Dream is a developer tool for the moment your UI is ready and the backend isn't. It intercepts fetch() and XMLHttpRequest on any page you are testing and answers with the response you defined — no proxy, no server, no account. WHAT YOU CAN DO • Intercept fetch and XHR via rules — match by URL pattern and HTTP method • Return custom JSON, status codes, response headers and simulated latency • Live traffic console — every request shows up as "mocked" or "pass-through", filterable by method, status and URL • "Mock this" — turn any real request into a rule with one click • Import / export rule sets as JSON to share with your team • Detached resizable window mode, per-tab badge counter, master switch, undo/redo • Tri-state groups, drag-and-drop, per-rule CORS toggle • Seven UI languages, six manga-inspired themes PRIVACY Mock Dream does not collect, transmit or sell any user data. Every rule and every traffic entry stays on your device, inside storage.local. No telemetry, no analytics, no remote code, no cloud sync. Full policy: https://mock-dream.lovable.app/privacy WHY THE BROAD HOST ACCESS The extension requests <all_urls> because developers test against any domain they own — localhost, staging, production debugging. The interceptor only acts on URLs matching a rule you wrote yourself.
