DiffReady – Visual Website Comparison

Compare a webpage with a saved baseline. Spot visual, content, and metadata changes locally.

See exactly what changed on a webpage. DiffReady saves a baseline of the page you choose, then compares it with the current version. Use it after editing a website, reviewing a deployment, checking a staging page, or validating client changes. WHAT DIFFREADY COMPARES • The visible browser viewport, with a before/after slider • Pixel differences, shown in a clear difference map • Headings, paragraphs, lists, tables, and other visible text blocks • Page title, meta description, canonical URL, language, headings, link count, and image count BUILT FOR PRACTICAL REVIEWS • Save or replace a baseline in one click • Ignore selected CSS selectors in content comparison • Adjust visual sensitivity • Keep the ten most recent reports • Export a standalone HTML report for a teammate or client PRIVATE BY DESIGN DiffReady works locally. It has no account, analytics, advertising, or remote server. Baselines, screenshots, settings, and reports stay in Chrome storage on your device unless you explicitly export a report. DiffReady reads a normal HTTP or HTTPS page only after you click the extension. It cannot run on Chrome internal pages or other browser-restricted pages. Note: automated comparison helps find changes but does not replace manual quality assurance.
