I built Hearthline because the big platforms are great for collecting genealogy data, but terrible at helping you understand it. Your family tree sits there as a database, but you never get a real sense of the patterns, the gaps, or the shape of your family across generations. Hearthline fixes that. Drop in your GEDCOM file and instantly get 17 analytical views: lifespan distributions, geographic spread, family size patterns, generation depth, surname frequency, and more. Your data stays local.

It's fully client-side. Your GEDCOM never leaves your browser. For genealogists who've spent decades building their tree, that data is deeply personal. You shouldn't have to hand it to a company to get analytics on it.
It updates as you work. As you fill in your tree and re-export your GEDCOM, Hearthline reflects the changes immediately. Watch gaps fill in, track how your tree grows, see your research progress in real time.
I built this as a solo side project alongside my day job as a data scientist. One-time purchase, no subscription, runs entirely in your browser.
