How cloud preview works
Visual QA

Catch the Safari bug before your client does.

Pick pages and devices, then hit Capture. Your team reviews every screenshot and signs off in one place.

  • Chromium, Firefox, Safari and real iPhone Safari
  • Five sizes, from wide desktop to Android
  • Reject a shot and it's flagged for a fix
See Visual QA
The ThemeSync New scan dialog: Chromium selected as the browser, Desktop and iPhone 14 selected as devices, 8 pages selected, and a Capture button showing 16 captures.
Real screen from the app

Sixteen screenshots. One click.

Eight pages on desktop and iPhone 14 is 16 captures you never take by hand.

Client feedback

Clients point at the page. You see the exact spot.

Send one link, no account needed. Every comment is pinned to the element, with the device and browser attached.

  • Pins stay on the element at any screen size
  • Reply, resolve and sign off page by page
  • Share for a day, a month, or longer

Live theme tracking

The live theme changes only when you say so.

ThemeSync backs up the live theme to git every few minutes, edits from the Shopify admin included. Code goes back to the store when you click Deploy.

  • Spots live themes nobody is tracking yet
  • A full history of every admin edit
  • Push to a draft first, publish when ready
