Questions
Frequently Asked
Family Tree Maker is a desktop program for Windows and Mac that syncs your tree with Ancestry.com and FamilySearch and stores it as a file on your computer, sold as a one-time purchase. AncestorOS is a browser-based platform that runs on any device with nothing to install, adds Evidence Explained citation tools, and includes a practice toolkit for professional genealogists. They overlap on tree-building but differ most on installation, record syncing, and business features.
It can be, depending on what you need. AncestorOS is a strong alternative if you want software that runs in any browser on any operating system with nothing to install, built-in Evidence Explained citation templates, and tools to run a genealogy business. It is not a match for Family Tree Maker's deep Ancestry TreeSync or fully offline desktop use. Read the comparison above to see which strengths matter to you.
Yes, partly. Export a GEDCOM file from Family Tree Maker (File then Export), then import it into AncestorOS. People, relationships, names, and dates transfer. Note that AncestorOS does not import sources or media embedded in a GEDCOM file, so citations and photos attached in Family Tree Maker won't carry over automatically — you would re-add media in AncestorOS.
Not in the same way. Family Tree Maker stores your tree as a file on your computer and works fully offline. AncestorOS runs in your web browser and needs an internet connection. It is an installable PWA, so it can live on your home screen like an app, but it is not a native offline desktop program. If uninterrupted offline access matters most, Family Tree Maker has the edge.
No. Family Tree Maker's signature feature is TreeSync with Ancestry.com and syncing with FamilySearch. AncestorOS does not connect to Ancestry, FamilySearch, or any record database, and it has no automated record hints. You bring your own research in and cite it yourself. If deep Ancestry integration is your priority, Family Tree Maker is the better fit.
They use different pricing models. Family Tree Maker is a one-time purchase of approximately $79.95 (as of 2026). AncestorOS is a subscription: $15/month or $150/year for Hobbyist, and $40/month or $400/year for Pro, with no free tier. Over several years Family Tree Maker can cost less up front; AncestorOS trades that for always-current software and, on Pro, business tools Family Tree Maker doesn't include.
AncestorOS Pro is built for the practice side. Its $40/month plan adds client management, projects, billable time tracking, invoicing, and expenses, plus 14 Evidence Explained citation templates — none of which Family Tree Maker bundles. Family Tree Maker remains excellent for the research itself, especially deep Ancestry syncing and offline work. Many professionals use a records or desktop tool for research and AncestorOS to run the business.
