Profile
A platform for comparing DNA data across multiple testing services to find genetic relatives and trace family connections.
GEDmatch, founded in 2010, is a genealogy platform that allows users to compare DNA data across multiple testing services, including AncestryDNA, 23andMe, and FamilyTreeDNA. The platform gained widespread attention in 2018 when it was used by law enforcement to identify the Golden State Killer, highlighting its potential for forensic applications. GEDmatch offers a suite of tools for genealogical research, including the One-to-Many DNA Comparison tool, which helps users find genetic relatives by scanning their DNA against a database of over two million profiles.
The platform operates on a freemium model, with basic features available for free and advanced tools accessible through a $10/month Tier 1 subscription. Recent developments include the launch of a new AutoSegment Split tool in October 2025, which streamlines DNA analysis by automatically determining overlapping segments on opposite sides of the family tree. GEDmatch continues to innovate, with plans to unveil a redesigned user interface later in 2026. Despite its utility, the platform has faced scrutiny over privacy concerns, particularly after a 2020 data breach that exposed users' DNA profiles to law enforcement searches.
