Show HN: Swarm, an offline family tree app for macOS
github.comHi HN! My wife and I got deep into our family genealogy and wanted to map out all our relatives - but keep the data on our own Macs instead of uploading it to a genealogy service. Nothing we found did that, so we built Swarm, a native macOS app in Swift.
It's built on GEDCOM 5.5.1, the universal genealogy file standard, so your tree exports cleanly to other ancestry apps if you ever want out. Example trees of famous historical families are included to play with.
Features: multiple ancestry views (tree, fan, world map), media files, GEDCOM import/export, PDF export, tree merging, and kinship naming.
Fully open source, no AI in the app, no internet connection required, no account required. Would appreciate any feedback!
I really like that it can be used entirely offline for privacy reasons, but it would be cool if it could search for relatives online to help populate the local tree from sources like Ancestry, etc.
I will see if I could add it as an optional opt-in feature! Thank you for the feedback!
Consider supporting references to https://www.familytree.org resources (each person has an xxxx-yyy identifier).
Cool idea, thank you for suggestion!
Really cool idea. How well does the app handle merging two large family trees?
It worked fine in internal testing with sample data, but I've yet to find a real person with two trees that need merging to make a proper test
