Founded in 1996 by Brewster Kahle and Bruce Gilliat and backed by Jacqui Safra's Etoile Investments as a commercial offshoot of the Internet Archive, Alexa Internet created related links derived from user behavior (a form of collaborative filtering) for users of the Internet Explorer and Netscape Navigator web browsers. Engineers at Alexa created the Internet Archive's Wayback Machine. Alexa also supplies the Internet Archive with web crawls. Other people connected with Alexa Internet prior to its acquisition include: Carl Feynman (consultant), Danny Hillis (board member), Patrick Tufts (inventor of Alexa's collaborative filter) and Scott Hassan (founder of eGroups).

In 1999, Alexa was acquired by Amazon.com for about $250 million in Amazon stock. The "site info" link on the Alexa site lists related links for websites and also records how much web traffic they receive. Alexa began a partnership with Google in spring 2002, and with Open Directory in January 2003. Today, Alexa is primarily a Google-based search engine, an Open Directory-based web directory, and a supplier of site information.
