The CI-driven alternative to Previewed.

Previewed is a polished visual editor — designers craft each screenshot, pick a frame, publish. ScreenStack is built for the other shape: dev teams whose screenshots refresh automatically every push, with Web Capture for marketing-site screenshots and an SDK that captures from the live app.

ScreenStack
two workflows · different jobs

Designer workflow vs developer workflow.

keep Previewed if

A designer crafts every screenshot

  • → Hand-tuned, layered, design-first screenshots
  • → Mobile-app editor is your primary interface
  • → Release cadence is monthly+ — manual works fine
  • → Phone-focused; no web app or dashboard to capture
switch to ScreenStack if

CI keeps your store assets fresh

  • → UI changes faster than a designer can re-craft
  • → Flutter / RN / web stack (SDK covers all three)
  • → Marketing site + dashboard screenshots needed
  • → Multiple apps, multiple device sizes, one project model
