webtrees turns a GEDCOM family file into a private, collaborative genealogy website where relatives anywhere browse ancestors, add photos and sources, and edit together under privacy rules the owner controls. Import a file and each person gets a page of facts, events, and citations, with tabs for families, sources, places, media, and albums and a navigator that jumps to parents, spouses, children, and siblings. Pedigree, fan, hourglass, compact, descendant, interactive, lifespan, relationship, and timeline charts show the same people from different angles, and a pedigree map plots ancestors' birthplaces on OpenStreetMap. Lists sort and filter individuals, families, sources, notes, repositories, and media, with branches that group people by surname. A calendar surfaces births, deaths, marriages, and anniversaries for any day, month, or year, in Gregorian, Julian, Jewish, Hijri, or Jalali dates. Printable PDF reports cover Ahnentafel, family group, descendancy, birth, death, and cemetery records, and search offers general, advanced, and search-and-replace modes for authorized users. Privacy rules apply per site, tree, user, record, and fact, so only authorized users see living people and sensitive details. Editors propose changes, moderators approve them, one site hosts several trees, and the interface comes in more than 60 languages. GEDCOM export lets every tree move to desktop genealogy programs. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.
