Score: 7.0/10 (Innovation: 6, Technical: 8, Documentation: 8, Utility: 6)

Swarm is a native macOS offline family tree application that builds, visualizes, and exports GEDCOM-based genealogies with no cloud dependency. It distinguishes itself with deep kinship terminology (English and Russian), robust GEDCOM 5.5.1/7.0 support including GEDZIP, safe merge and rollback semantics, and a native Swift implementation. The project is well-documented, thoughtfully designed for data durability, and fills a gap for privacy-conscious genealogy users on macOS.

Target audience: macOS users interested in genealogy, family historians, and privacy-focused individuals
