Hide part of a page — not the whole page — behind a sign-in or an access code, and show everybody else a teaser instead.
Most apps that do this paint a panel over content that is already in the page. This one does not send it: until the door opens the hidden words are not in the page at all. View the source of a locked block and there is nothing to find.
Two locks, both free. Signed-in members: who is asking is read on our own server, from a signed token, so nothing in a page can fake it. An access code: works on any site, with nothing else installed and nobody registering for anything.
Put a block anywhere, as often as you like: a card, a full-width band, a line inside an article, or a button that opens over the page. Every colour and every word is yours.
Free: no cap on blocks or placements, both locks and every design control. No watermark and no badge on any plan, ever. Pro adds more doors, labelled codes with expiry dates, a scheduled opening day and a record of every opening.
It never registers anybody, never sends an email, never takes a payment, never reads another app’s plan and never creates a page.
Runs on Studio, the classic editor and Harmony.
