It's a Mac application that downloads Web sites from the Internet automatically. It accomplishes this by duplicating its directory structure while asynchronously copying the site's webpages, photos, PDFs, style sheets, and other items to your local hard disc.

It can make local copies of Web sites. By default, SiteSucker "localizes" the files it downloads, allowing you to browse a site offline, but it can also download sites without modification. An enhanced version can download embedded videos, including embedded YouTube and Vimeo videos.
