Questions

Frequently Asked

RootsMagic is a mature Windows and Mac desktop application (with a free companion mobile app) that you install and run locally, with direct record hints and two-way syncing to the major record databases. AncestorOS is a web-based platform that runs in any browser on any operating system with nothing to install, and adds a professional practice toolkit including client management, invoicing, and time tracking. RootsMagic suits researchers who want offline desktop software and record-site integration; AncestorOS suits those who want a browser-based tool and, on the Pro plan, business tools.
RootsMagic is a one-time purchase of around $39.95 as of 2026, plus a free limited Essentials edition, so over several years it is cheaper than any subscription. AncestorOS is a subscription starting at $15/month (or $150/year) for the Hobbyist plan, with Pro at $40/month. If long-term cost is your only concern, RootsMagic's one-time price wins. AncestorOS charges a subscription because it is a hosted, always-updated web service that also includes business tools.
Yes, via GEDCOM. In RootsMagic, export your file to a GEDCOM (.ged) file, then import it into AncestorOS from the GEDCOM Import page. People, relationships, names, and dates transfer automatically. Note that AncestorOS does not import source citations or media files embedded in a GEDCOM, so those would need to be re-added after import.
No. RootsMagic is a desktop application that works fully offline once installed. AncestorOS is a web application and needs an internet connection to use. If you often research without internet access, RootsMagic or another desktop program is the better fit.
Yes, and it is one of RootsMagic's biggest strengths. Its WebHints feature surfaces potential matches from Ancestry, FamilySearch, MyHeritage, and Findmypast, and TreeShare lets you sync people, events, sources, and photos back and forth with your Ancestry tree. AncestorOS does not connect to any external record database or offer record hints — you research on those sites separately and record your findings in AncestorOS.
Both take citations seriously. RootsMagic has long included hundreds of source templates, many based on Evidence Explained. AncestorOS includes 14 Evidence Explained citation templates across 11 record categories on its Pro plan, each generating all three citation forms: a full reference note, a short note, and a source-list entry. If you want Evidence Explained templates inside a modern web app, AncestorOS fits; if you want the deepest desktop template library, RootsMagic is excellent.
RootsMagic is designed for building and documenting family trees, not for running a practice — it has no client management, invoicing, or time tracking. AncestorOS Pro at $40/month adds a client CRM, projects, billable time tracking, invoicing, and expense tracking alongside the research tools, so professional genealogists can manage clients and research in one place.
