Swarm Rebuild

Wipe any page to a blank canvas and watch a swarm of multiplayer cursors rebuild it, live.

Turn any website into a live design session. One click wipes the page to a blank canvas, and a swarm of colorful multiplayer cursors rebuilds it in front of you, piece by piece, until it looks exactly like it did before. ✦ WHAT YOU'LL SEE • The page fades away and a team of named cursors gathers in the middle of the screen • Boxes dragged out with a crosshair and a live W × H size badge, then filled in • Headlines and paragraphs typed out with a blinking caret, with big titles growing to full size • Borders drawn stroke by stroke with the pen tool • Ruler guides dragged in from the side, with text snapping neatly onto them • Cards, menu links and list rows duplicated into place with spacing measurements, then retyped • Images revealed with a smooth top-to-bottom sweep ✦ HOW TO USE • Click the toolbar icon or press Alt+Shift+S on any page • Scroll and the swarm chases you, calling in more cursors the faster you go • Turn on Tour to auto-scroll at the swarm's pace, perfect for screen recordings • Pick a build speed: 1×, 2× or 3× • When it's done, the cursors flock around your mouse • Go live fades back to the real, clickable page. Replay builds it all again • Press Esc or click the icon again to exit at any time ✦ KEYBOARD SHORTCUTS Alt+Shift+S start / stop · 1 / 2 / 3 speed · T tour · M mute · R replay · L go live · Esc exit ✦ SOUND A soft, clicky soundtrack is generated live in your browser: keyboard clicks while typing, mouse clicks on every drag, gentle piano notes as pieces land and a warm chord when the page is finished. Press M to mute. Your speed and sound choices are remembered. ✦ GREAT FOR • Screen recordings, demos and social posts • Showing off a website you designed • Teaching how web pages are built from boxes, text and images • Just having fun on any site ✦ PRIVACY Nothing is collected, stored on a server or sent anywhere. The extension only runs on the tab you click, at the moment you click it, and everything happens inside your browser. Your settings and rating choice are saved only on your own device. ✦ GOOD TO KNOW • Chrome doesn't allow extensions on chrome:// pages, the Chrome Web Store or the built-in PDF viewer • It's a visual rebuild for fun: page animations pause while the swarm works, and videos or canvases far below the first screen are shown as placeholders ✦ CREDITS Inspired by the work of Joel Califa.
