What the demo is
The real application on a week of sample data, for a couple of days. One thing about it surprises people, so it is first.
The demo is the real application, loaded with a week of sample data, for 48 hours. No card, no signup, no email. Then it deletes itself.
What you can do in it
Everything. It is not a video, a screenshot tour or a limited build — it is baybay with a pretend baby in it. Log feeds, start naps, edit entries, look at the charts, change the bottle amounts, open it on your phone. Nothing is switched off.
The one thing that surprises people
Demo data does not carry over. Subscribing builds you a fresh, empty household — it does not adopt the demo you were playing with.
So if you have started logging your own baby's feeds into the demo, those entries will not follow you. Either subscribe first and log there, or expect to re-enter the day or two you have done. Worth knowing now rather than after paying.
Getting back into it
A demo has no account, no email address and no password, so there is nothing to sign back in with. That used to be a dead end for anyone who closed the tab — the only thing left to do was start a second demo and lose whatever had been logged into the first. Two things fix it.
On the same browser: go back to baybay.baby. A bar across the top of the page offers your demo back, and one press opens it. It does not matter whether you are on the same wifi, the same network or the same city.
On a different device: the same bar shows your household code. Open the demo's address on the other phone or laptop, type the code at the sign-in screen, and you are in — exactly the way a partner or a sitter joins a real household.
The code is also printed on the demo's own sign-in screen, so knowing a demo's address is enough to open it. That is deliberate and it stops at demos: a real household keeps its code behind the sign-in, on the settings screen, where only somebody already inside can read it.
Why it expires
A demo household is a real household on a real server, seeded and then thrown away. Giving it 48 hours is long enough to use baybay across a couple of nights, which is the only way to tell whether a tracker suits you, and short enough that we are not quietly running an unpaid service.
What happens when it expires
The household is deleted and the address stops working. Nothing to cancel and nothing to clean up. If you had bookmarked it, that bookmark will show a "not found" page — the demo is gone rather than locked.
After the demo
The hosted plan is $7 a month and takes about a minute to start: we run the server, take the backups and keep it updated, and you get a permanent address for your household. See the plans.
Or run it yourself for nothing — the whole application is open source. Which one suits you.
