What it does
A single device over the live page — realistic frame, rotate, focus mode, and fully custom sizes.
A multi-device canvas: several phones and tablets side by side, each with its own preset, rotation and zoom.
iPhones, Android phones, tablets, foldables and monitors — real metrics, real pixel ratios, real status bars.
The mobile User-Agent is applied at the network layer and mirrored to JavaScript, so sites respond like they would on a real phone.
Mirror scroll, clicks and typing between the desktop page and every device on screen.
Export a device-masked PNG, the full view, or the entire scrollable board in one image.
Record the preview and export WebM or MP4, with trim and playback-speed controls built in.
No analytics, no telemetry, no external APIs. Settings never leave your machine. 52 languages, light and dark theme.
