Show HN: Swarm, an offline family tree app for macOS

原文链接 ↗ ·samoilev
Hi 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

AI 分析

痛点:家谱爱好者想把家族数据保存在本地、不上传到 Ancestry/MyHeritage 等云端家谱服务,但市面上缺少好用的离线原生家谱工具。

目标用户:注重数据隐私的家谱/族谱研究者,尤其是 macOS 用户和 GEDCOM 标准用户

证据: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

变现:付费买断制($30-60 一次性授权)或开源核心+付费高级版(跨平台同步、iOS/移动端、加密云备份、多用户协作、高级 PDF/打印报告);也可做一次性付费的模板/族谱打印服务

MVP:2 周内用 SwiftUI 或 Electron+Tauri 做一个只做核心闭环的 MVP:GEDCOM 5.5.1 导入/导出 + 可交互树视图 + 本地加密存储 + PDF 导出,先只支持 macOS,突出「零联网、零账号、数据不出本机」这一个卖点,用免费版引流、导出高清/批量报告收费

竞品:MacFamilyTree、Gramps (免费开源)、Ancestry、MyHeritage、RootsMagic、Heredis、Family Tree Maker

摘要:开发者因不满家谱数据必须上传云端,用 Swift 写了一个离线 macOS 家谱应用 Swarm,基于 GEDCOM 5.5.1,支持树/扇形/地图视图、媒体文件、导入导出、PDF 导出和树合并,完全开源、无需联网或账号。帖子里没有任何付费意愿或收入证据,HN 热度也极低(5 分 4 评论)。「本地隐私家谱」确实是已有付费先例的细分市场(如 MacFamilyTree),但免费开源竞品 Gramps 和行业巨头林立,独立开发者只能靠隐私这一单点切入,天花板有限。
