Description
Capture responsive website widths and create branded client QA reports locally. ViewportProof turns the website page open in Chrome into a professional responsive QA package. Capture the active page at mobile, tablet, and desktop widths, inspect full-page screenshots, review local rules-based signals, add your own pinned findings, and download a client-ready report. Each package can include: • A branded, searchable PDF report • Original full-resolution PNG screenshots • Requested and measured viewport widths • Human-confirmed findings and editable recommendations • A SHA-256 integrity manifest ViewportProof helps agencies, freelancers, developers, and QA teams replace unexplained screenshot folders with a clear handoff another person can act on. Privacy is part of the architecture. Captured website pixels, URLs, page titles, findings, client names, notes, logos, PDFs, and PNGs remain on your computer. Anonymous product events are optional and off by default. No account, AI service, Google authorization, or cloud rendering service is required. Important limitation: ViewportProof validates responsive CSS widths in desktop Chrome. It does not emulate physical phones, Safari, touch input, mobile user agents, device pixel ratios, or independently scrolling application panels.
