Free Responsive Website Tester - Preview URL across 4 devices at once — free, no signup

Hey hunters! 👋 I built Sorawi Respo out of personal frustration. Every responsive review meant: 1. Open DevTools device toolbar 2. Pick a width, check layout 3. Pick another width, check again 4. Try to mentally compare — miss the overflow that only shows at 768px 5. Screenshot each, stitch in Figma for the client Sorawi Respo does it in one view: • Paste URL → see desktop, laptop, tablet, mobile at once • 34 real device presets (Studio Display → iPhone SE) + custom 240-4096px • Drag, overlap, zoom, toggle frames — it's a canvas, not a grid • One-click export: PNG, JPG, SVG, WebP, PDF with transparent/white/checkered backgrounds • Share links carry the exact device sizes & arrangement so reviewers see the same view • Free, no signup, runs in the browser Try it: https://respo.sorawi.com Happy to answer questions on how the preview relay works (it bypasses most framing blocks), how capture reuses the loaded iframe (no second render), or the export pipeline.
