A home for your data
Your family history, kept on your terms.
Linea Codex is a place to keep your genealogy — not a vault that keeps it from you. Everything stays open, portable and on your own device.
Offline-first by design
The whole app runs locally in your browser through OPFS. On a plane, in an archive basement, anywhere — no connection required.
No server, no telemetry
Your tree never touches a server, because there is no server. Nothing is uploaded, tracked or analyzed. Privacy here is not a setting; it is the architecture.
No vendor lock-in, ever
Your data is plain GEDCOM text plus ordinary media files. Open it in any other program tomorrow — we earn your stay by being good, not by trapping you.
Take everything with you
Export your project as standard GEDCOM, or bundle the file and all its media into a single GEDZIP archive with one click.
Reads the world's files
More than 30 character encodings — including legacy ANSEL — with automatic detection, so files from any era or country just open.
Many trees, one workspace
Keep as many projects as you like, side by side, and switch between them instantly.
Built not to lose your work
File operations are journaled and crash-safe, so an interrupted save or a closed tab will not corrupt your tree.
Make it the home for your tree.
Open Linea Codex in your browser — bring a GEDCOM, or start fresh.
