Sorawi Respo vs browser viewport resizers

What viewport resizers do well

Browser DevTools responsive mode, window resizers and single-viewport checkers are fast for checking one breakpoint. They are built into the browser, they do not require another tab, and they are familiar to anyone who has inspected an element.

Where they fall short

• One width at a time — you can see 390 px or 768 px, but not both at once.
• No composition — screenshot tools capture the active tab; stitching multiple widths into one image is manual.
• No real device context — a viewport number is not the same as seeing a page on a device frame with a familiar shape and scale.
• Limited export — DevTools can take a screenshot, but not a multi-device composition with backgrounds or share links.

What Sorawi Respo adds

• Four viewports at once — desktop, laptop, tablet and mobile render simultaneously, so responsive behavior becomes a glance instead of a sequence.
• Free-form stage — drag, overlap, zoom and reorder devices. Capture exactly the composition you want, not whatever the browser happened to show.
• Five export formats — PNG, JPG, SVG, WebP or PDF with transparent, white or checkered backgrounds. Download one file ready for a deck, ticket or client update.
• Shareable previews — copy a link that recreates the exact device sizes and visibility. Reviewers open it and see the same responsive view without installing anything.
• 34 real device presets — from Studio Display to iPhone SE, with custom viewports and portrait/landscape rotation.

Use both

Viewport resizers are still useful for rapid breakpoint debugging. Sorawi Respo is useful when you need to compare, capture and share responsive behavior with a team or client. The two approaches cover different parts of the same workflow.
