The web app plays inside a clean browser window with traffic lights and a URL bar on a soft backdrop.

What it does

Built on Safari by magic-ui, MIT. The write-up and recipes below are varg's.

Rounded window, minimal chrome, real domain in the bar, big soft shadow, 6–10% padding around it on a gradient.

When: Every web product demo; it tells the viewer "this runs in your browser".

Watch out: Do not use a cluttered browser with tabs, bookmarks and extensions from your own machine.

Timing: Window in 0.6 s (y 40 px, scale 0.96 → 1), then hold; zoom moves happen inside the window.

Also called: Safari mockup, browser chrome, web app frame

In FFmpeg

ffmpeg -i bg.png -i rec.mp4 -i chrome.png -filter_complex "[1]scale=1500:-1[r];[0][r]overlay=210:150[a];[a][2]overlay=210:96" -shortest out.mp4

In HyperFrames

npx hyperframes add browser-device-stage

Put the screen recording <video class="clip"> in the stage's screen slot; animate the stage wrapper for moves.

In Remotion

// npx shadcn@latest add @magicui/safari
<div style={{width:1500}}><Safari url="app.acme.com" videoSrc={staticFile('rec.mp4')}/></div>
