Why a GEDCOM-centric tool serves you

Most genealogy programs keep your family tree inside their own database, and hand you an export when you ask for one. Linea Codex works the other way round: your project is a GEDCOM file, and everything the app does is in service of keeping that file clean, correct, and yours. This page makes the fuller case for that choice — and what it means for your research over the long run.

(New to GEDCOM itself? The short version is in What is Linea Codex?.)

Your data stays yours

GEDCOM is an open, documented standard — not a private format invented by one company. Because your work lives in that standard rather than in a proprietary database, there’s nothing to be locked inside:

No lock-in. You’re never trapped in one program by the cost of getting your data out. What you edit here is the same .ged file you can open elsewhere — there is no separate “real” copy held in a format only this app understands.
You can leave whenever you like. Export at any time and your complete tree comes with you. A tool you can walk away from is a tool you can trust to stay.
It’s stored on your device, not ours. Linea Codex is offline-first: your file lives in your browser’s local storage and never leaves your machine unless you send it somewhere. See Where your data lives.

Take it anywhere — and use other tools too

A standard format is a passport. The same file opens in countless desktop programs, websites, and viewers, which means Linea Codex never has to be your only tool:

Render a wall chart in a dedicated charting program, publish an online tree, run DNA-match analysis, print a book — each on the same underlying data.
Move between applications as your needs change, without re-keying a single name.

Linea Codex is built to be an excellent place to keep and tend your tree; it’s happy to let other tools do the things they do best, because your data isn’t hostage to any of them.

Flexible enough for real research

GEDCOM can record a remarkable range of genealogical detail — people and names, families, vital events, sources and citations, notes, repositories, and multimedia. The standard also evolves: 5.5, 5.5.1, and 7.0 each express slightly different things, and Linea Codex converts faithfully between them through a common model.

And for the rare case the standard has no tag for? GEDCOM lets you add your own custom tags — and Linea Codex preserves and works with them rather than discarding them. So you’re never forced to throw away a fact just because there’s no official place to put it. See the recipe When GEDCOM has no tag for it.

Correct by construction

Owning your data only matters if the data is good. A GEDCOM file is only as portable as it is correct — a file riddled with specification errors may open badly, or not at all, in the next program. That’s why two of the app’s headline capabilities exist:

Validation continuously checks your file against the GEDCOM specification, so the file you keep is the file that opens cleanly everywhere else.
Conversion moves your tree between GEDCOM versions on a compliant-in, compliant-out basis.

These aren’t the reason to use Linea Codex — owning portable data is. They’re the proof that the data you own is genuinely portable.

It outlives the app

Software comes and goes; file formats with decades of adoption tend to stay. A plain-text, openly documented standard is about the safest place your life’s research can live — readable far into the future, by you or whoever inherits your work, with or without this particular app.

That’s the whole philosophy: Linea Codex is the home you keep your genealogy in, not the cage it lives in.
