Famhoo.com, Kidrex.org and Quinturakids.com are all search engines specifically designed as family-friendly. Famhoo.com claims to provide access to everything good the Internet has to offer, without the bad. Kidrex.org bills itself as a safe search for kids, by kids. Quinturakids.com is a child-friendly version of the Quintura visual search engine.
Beyond these search engines designed to be family-friendly, most major search engines also offer a safe search option that blocks content that is inappropriate for young ages. For example, Google SafeSearch removes explicit content from its results for users who have it enabled. Kidrex.org leverages this technology in addition to its own database of approved websites.
