NewsGuard is a browser extension that provides rating labels for online news sources. It rates the credibility of news sites according to their general trustworthiness and whether or not they have a history of running fake news stories. These ratings are created by qualified journalists and based on a publicly available list of criteria.
AllSides aggregates news stories from all around the web and provides media bias ratings for each. Top news stories from outlets rated left-leaning, right-leaning and centrist are displayed side-by-side to give a well-rounded picture of the media's coverage of current events.
Snopes.com covers urban legends, rumors, e-mail forwards, and other stories of unknown or questionable origin. Snopes is created and maintained by a small staff of researchers and writers and receives no funding in any form from any person, group, agency, or organization.
"PolitiFact is a fact-checking website that rates the accuracy of claims by elected officials and others who speak up in American politics. PolitiFact is run by editors and reporters from the Tampa Bay Times, an independent newspaper in Florida, as is PunditFact, a site devoted to fact-checking pundits. The PolitiFact state sites are run by news organizations that have partnered with the Times. The state sites* and PunditFact follow the same principles as the national site."

From FactCheck.org's "Our Mission" page: FactCheck.org is a "nonpartisan, nonprofit 'consumer advocate' for voters that aims to reduce the level of deception and confusion in U.S. politics. We monitor the factual accuracy of what is said by major U.S. political players in the form of TV ads, debates, speeches, interviews and news releases. Our goal is to apply the best practices of both journalism and scholarship, and to increase public knowledge and understanding.
FactCheck.org is a project of the Annenberg Public Policy Center of the University of Pennsylvania.
