Features

Sorawi Respo is a free, browser-based responsive website tester. Paste a URL and see it rendered on desktop, laptop, tablet and mobile screens at once — then arrange, capture and export the composition.

Preview across every device

  • Four device categories — desktop, laptop, tablet and mobile — rendered side by side on one canvas.
  • 34 real device presets, from Studio Display and MacBook Pro to iPad Pro and iPhone 13 mini.
  • Custom viewport sizes from 240 to 4096 px on every device, saved between visits.
  • Portrait and landscape rotation for tablet and mobile frames.

An interactive device stage

  • Drag and drop devices anywhere on the stage to compose the view you want.
  • Overlap and layer — the z-order updates as you drag, and a reset button restores the default arrangement.
  • Free and comparison layouts — switch between a free-form canvas and aligned side-by-side frames.
  • Stage controls — zoom the whole canvas, show or hide a grid, toggle device details, and set a screenshot delay so frames are fully loaded before capture.

Capture & export

  • One-click capture with an instant preview of the result before you download anything.
  • Device frames on or off — export the full mockup composition or just the bare website screens.
  • Five formats — PNG, JPG, SVG, WebP and PDF, each downloaded as a single file.
  • Three backgrounds — transparent, white or checkered, with transparency supported in PNG, WebP and SVG.

Share & workflow

  • Share links that reproduce the exact URL, device sizes and visibility for whoever opens them.
  • Check history of recent URLs, kept in your browser and clearable at any time.
  • No account, no install — the whole tool runs in your browser and never modifies the websites you preview.
