List of fact-checking websites

This list of fact-checking websites includes websites that provide fact-checking services about both political and non-political subjects.

The Reporters' Lab at Duke University maintains a database of fact-checking organizations that is managed by Mark Stencel and Bill Adair. The database tracks more than 100 non-partisan organizations around the world. The Lab's inclusion criteria are based on whether the organization

• examines all parties and sides;
• examines discrete claims and reaches conclusions;
• tracks political promises;
• is transparent about sources and methods;
• discloses funding/affiliations;
• and whether its primary mission is news and information.
