HTML Compare

See every change between two pages, right on the page. HTML Compare works with any web page you can open by URL, including a page on localhost. Put two addresses side by side and it marks what changed: text, images, links, and styles. The marks sit where a visitor would see them, and a list tells you the kind of change and which page it is on. Use it before you publish a page update, a campaign, a language version, or a redesign. Compare at desktop or mobile width, then switch to the live page and keep scrolling in sync.
