About Viewport Buddy

What Viewport Buddy does

Viewport Buddy is a web-based responsive screenshot crawler. You add a website, it reads the site’s sitemap, and it captures a full-page screenshot of each page you select at phone, tablet, laptop and desktop widths. The screenshots sit side by side for review, and automatic checks flag horizontal overflow, small text, small tap targets, oversized images and overlapping text.

Optional AI reviews give a second opinion on selected screen sections. Scheduled re-crawls with visual diffs show what changed between releases, and results can be shared as a report link, a PDF, or read-only client access with a private link and PIN.

Who it is for

• Site owners who want to see every page on a phone without opening each one by hand.
• Developers checking a release or redesign for layout regressions across screen sizes.
• Agencies that review client sites regularly and need to show clients what was found and fixed.

Why it exists

A homepage usually gets tested on a phone; the other pages often do not. Device emulators and browser extensions show one page at a time, so checking a whole site at several widths turns into hours of clicking and manual screenshots. Viewport Buddy works from the sitemap instead, so one crawl covers every selected page at every chosen viewport and keeps the results for comparison.
