Ancestris
Free desktop genealogy software that keeps family data in GEDCOM.
Ancestris is a free genealogy application for building and maintaining family trees on Windows, macOS, and Linux. It emphasizes user-controlled data by storing research in GEDCOM files rather than tying it to a paid service or proprietary database. The software includes tools for editing, visualizing, analyzing, merging, and publishing genealogy work.
Why it stands out
- Uses GEDCOM as the primary data format, reducing lock-in when changing software later.
- Free software with no stated limits on people, families, documents, or separate trees.
- Cross-platform desktop support across Windows, macOS, and Linux.
- Developed by genealogists over many years, with a volunteer user community for help.
- Includes analysis and cleanup tools beyond basic tree entry, such as duplicate detection and merge functions.
Good to know
- Requires installing desktop software; it is not presented as a hosted web or mobile app.
- The daily version is intended for newer functionality, while the stable version is the safer choice for regular work.
- The page describes tree-management software, not an online historical-record database or DNA matching service.
Under the radar: If your main tree is important, use the stable release for everyday editing and keep the daily version separate for testing newer features before trusting them with your primary GEDCOM file.
