Swarm

Native macOS family tree editor that keeps genealogy in plain GEDCOM files, fully offline.

Desktopfreeglobal

Swarm is a native macOS app for building and visualizing family trees that keeps everything as plain GEDCOM files on the user's own disk, with no account, cloud, or telemetry involved, and offline place search built in. It's for Mac users doing genealogy research who want their family history data to stay fully local and portable, including support for kinship terms and record encodings that most mainstream genealogy apps don't handle.
