WebCrawler is a metasearch engine that blends the top search results from Google Search and Yahoo! Search. WebCrawler also provides users the option to search for images, audio, video, news, yellow pages and white pages. WebCrawler is a registered trademark of InfoSpace, Inc. It went live on April 20, 1994 and was created by Brian Pinkerton at the University of Washington.

In July 2010, WebCrawler was ranked the 753rd most popular website in the U.S., and 2994th most popular in the world by Alexa. Quantcast estimated 1.7 million unique U.S. visitors a month, while Compete estimated 7,015,395 -- a difference so large that at least one of the companies has faulty methods, according to Alexa.
