Visual testing in a snap. MultiMo – Visual testing in a snap. Test your website on every screen size at the same time. MultiMo opens real phone and tablet viewports side by side in one Chrome tab. Scroll, click and type once, and every device follows. When you spot a layout bug, capture it in one click and paste a ready-made report into Jira or Slack. No device farm. No cloud queue. No uploading your staging URL to a third party. Everything runs inside your own browser. WHY TESTERS AND DEVELOPERS USE MULTIMO Checking a page at different breakpoints usually means resizing DevTools, repeating the same click on each size, taking screenshots by hand and then writing the bug report from scratch. MultiMo does that in one pass: • See several devices at once – iPhone, Android, tablet and desktop viewports on one screen • Interact once – scroll, click and type on one device and the others mirror it • Report faster – a screenshot and a formatted bug report are generated for you FEATURES SYNCED VIEWPORTS • Synced scrolling – scroll one device and the rest move to the same relative position, even when their page heights differ • Synced clicks and typing – menus, buttons, toggles and form fields are mirrored across devices • Synced navigation – follow a link on one device and every other device loads the same page • Sync on/off switch – turn syncing off whenever you want to inspect one device on its own • Touch mode – test with touch-style interaction instead of mouse behaviour REAL DEVICE SIZES • A built-in catalog of 49 device presets: iOS and Android phones, iOS and Android tablets, foldables, smart displays and desktops • Realistic phone and tablet frames, including notch, punch-hole camera and home indicator • Rotate any device between portrait and landscape • Add or remove viewports in place without reloading the others • Adjustable workspace zoom so more devices fit on your screen ONE-CLICK BUG REPORTS • Capture Layout Bug takes a screenshot of the device and writes a report with the device name, resolution, URL and timestamp • Copy the report as Markdown, ready to paste into Jira, Slack or any tracker • Copy the screenshot straight to your clipboard, or download it as a PNG • Full-page capture – tall pages are stitched together so nothing is cut off at the fold • Annotate screenshots to point at exactly what is wrong WORKS WITH YOUR SITE • Start from your current tab or paste any URL • Works with local, staging and production sites • Handles sites that normally refuse to load inside frames • Some sites, such as Google sign-in pages, block framing at the browser level and may not load inside a viewport WHO IT IS FOR • QA engineers and manual testers • Front-end and web developers checking responsive layouts • Agencies and freelancers showing clients how a site looks on every device • Product managers doing release sign-off • Founders and makers launching a mobile-friendly site FREE AND PRO FREE – forever • 2 synced viewports • Full device preset catalog • Synced scroll, click, typing and navigation • One-click bug capture with Markdown export • Full-page screenshots PRO • Unlimited synced viewports • Custom device sizes • Capture all devices in one click • Visual diff to spot differences between two viewports • Saved viewport sets so you can reload your usual test setup • Shareable sessions for teammates and clients Pro is available as ₹999 per month or ₹9,599 per year (about 20% less than paying monthly). Install the free version first, then upgrade from inside MultiMo whenever you need it. Payments are handled securely by Razorpay, and you can cancel at any time. PRIVACY • MultiMo runs entirely in your browser • The pages you test, your screenshots and your bug reports are not sent to any MultiMo server • No account is needed for the free plan • No analytics, advertising or tracking • Settings, saved viewport sets and plan status are stored locally in your browser • The only outside connection is the Razorpay checkout, and only if you choose to upgrade MultiMo needs access to all sites so that you can load any URL you choose into a device viewport and mirror your scroll and clicks between devices. It only acts on the pages you open inside the MultiMo workspace. HOW TO GET STARTED 1. Click the MultiMo icon in your toolbar 2. Choose "Current tab" or enter a different URL 3. Click Sync Viewports 4. Scroll, click and type on any device and watch the others follow 5. Click Capture Layout Bug when you find an issue SUPPORT Questions or feedback?

Note: MultiMo resizes viewports to match real device dimensions but does not emulate a device's user-agent string or pixel density. Always confirm important fixes on physical devices before release.
