Multi URL Viewer allows users to open and compare up to four websites side by side in a single browser window using resizable iframes. By eliminating the need to constantly switch tabs, it streamlines tasks such as layout verification, content review, and cross-site comparison.

Good to know: Some websites may restrict being loaded inside iframes due to security headers, which can prevent them from displaying properly in the viewer.
