What is Linea Codex?
Linea Codex is a place to keep, edit, and convert your family tree — and it runs entirely in your browser, offline, with your data never leaving your device.
Your tree is a file you own
Section titled “Your tree is a file you own”Your genealogy lives in a GEDCOM file: an open, text-based standard that genealogy programs have
read and written for decades. Linea Codex doesn’t lock your work inside a proprietary database — when
you’re done, you export the same kind of .ged file you could open in dozens of other programs.
That’s the whole idea: you own your data, and you can take it anywhere.
Why GEDCOM?
Section titled “Why GEDCOM?”GEDCOM is the closest thing genealogy has to a universal language:
- It’s portable. The same file opens in countless desktop apps, websites, and viewers — so you can visualise and share your research however you like.
- It’s durable. A plain-text open standard outlives any single application.
- It’s expressive. GEDCOM can record an enormous range of genealogical detail — and for the rare things it has no standard tag for, it lets you add your own custom tags.
Linea Codex is built around this standard rather than hiding it. Everything in the app — the editor, the validator, the converter — exists to help you produce clean, correct, standards-compliant GEDCOM.
