Responsive Mobile Simulator by MobileReady

MobileReady helps you find mobile layout problems and capture clear visual feedback. Preview the current webpage in simulated phone and tablet frames, compare screen sizes, check spacing and alignment, and take screenshots without repeatedly resizing the browser or opening developer tools.

Start free with available device presets, alignment guides and standard-resolution screenshots. Optional paid plans unlock additional devices and tools such as HD screenshots, annotations, element inspection, live styling and presentation mode; availability depends on the selected plan.

Optional recurring subscriptions are advertised at Professional $7.95/month or $59/year; Expert Solo $9.95/month or $95/year; Expert Team $19.95/month or $199/year. The selected plan, currency and billing period are shown before payment.

Billing in version 1.2.21: choose a plan inside the extension and complete Stripe-hosted Checkout. Your plan refreshes when you return. Manage plan changes and cancellation through the extension's billing button, which opens Stripe. No website customer account or manual purchase pairing is required. Restore a purchase or join a Team using an emailed verification code.

Version 1.2.21 processes simulation, inspection and screenshots locally. Optional usage analytics are off until you opt in. Requested licensing actions use necessary installation and verification data. User-requested PageSpeed measurement or reports send the displayed, sanitized page URL to Google with consent.

In version 1.2.21, Firefox preserves website security headers. Sites that refuse embedding may need to be opened in a normal tab instead. Device frames simulate viewports; they are not physical devices and do not replace final testing on real mobile browsers.
