LegacyTree

What it does

LegacyTree is a genealogy app for building a family tree with relatives. Each person carries photos, dates, places, a biography and tags. The tree can be explored and opened into profiles, and the same family can be read as a timeline of births, marriages and deaths. Behind it sit accounts, shared editing, privacy settings and a Supabase backend. The app was generated with Lovable, an AI app builder; the estate's own addition is a GEDCOM parser.

How it works

The interface is React and TypeScript with Tailwind and shadcn/ui, and the backend is Supabase: Postgres migrations, row-level access and edge functions. Concurrent edits use optimistic locking, likely duplicate people are flagged before a merge, and media is served through signed URLs. The project's own status file records that the main application most likely came from Lovable before this estate's tooling existed, so it is shown for what it does, not as hand-written work. The GEDCOM parser reads the standard genealogy exchange format and ships with a fictional sample family.

Worth knowing

• Interactive family trees whose members open into profiles with a video introduction, biography, favourite music and family links.
• Two trees researched separately can be matched on the people they share and linked, with the kinship path between any two relatives explained.
• Concurrent edits use optimistic locking, and likely duplicate people are flagged before a merge.
• Personal family exports are kept out of version control by rule.
