👋 You're exploring a demo family — 124 fictional people across three family lines. Ready to plant your own?
🌱 Your tree starts here
Add yourself first — then parents, grandparents, cousins.
Everything saves automatically on this device, and you can invite
family to help build it later.
💾 Your tree is saved on this device only. Download a backup so a cleared browser can never erase your work.
Your whole family in one 3D space — grandparents, uncles, aunts, cousins —
each branch fanned into its own sector so nothing ever hides behind
anything else. Marriages bridge the trunks as amber arcs.

Already use Ancestry, FamilySearch or MyHeritage? Export a
GEDCOM (.ged) file there and drop it on IMPORT here.

share & build it together
Hit SHARE and pick a role for a family member:
Viewer (explore only), Contributor (their edits come
back to you as suggestions to approve) or Co-author (edits
come back pre-approved). Send the link (or file) — it opens straight
into the tree. They press SEND CHANGES when done; you
drop that file on IMPORT and approve each change.
No accounts, no cloud — files and links only.
the time machine
Drag the year slider at the bottom: unborn relatives fade away, the
departed become ghosts — watch your family exist through time. ▶ plays.
■ 100% private. Your family tree is stored only in this
browser — never uploaded to us, and included only in files you choose
to export or share. This page loads no analytics and sets no cookies.
(The 3D library, a typeface, and the demo family's placeholder photos load
from public CDNs, which see your IP address as any website would; your own
family data is never sent anywhere.) Full details in our
Privacy Policy.
🌱 Bloomsly is brand-new and improving almost every day.
You're one of our very first families — your tree saves automatically on this device,
and the Export button keeps a backup you own. Tell us what to build next!
Share this tree
Your family member needs this same app file (send it once, or put
it on any shared drive). The link or file carries the whole tree plus their role —
when they open it, everything just works. When they send a changes file back,
drop it on IMPORT to review and merge it. Nothing ever touches a server.
