Visitor Queue

Zipper Visitor Queue — Visitor Queue is Zipper’s waiting room — it sits in front of your site on protected paths. When a path runs over its limit, extra visitors land on a holding page carrying your own brand: headline, message, accent colour, logo, their position in line, and an estimated wait. An admissions-per-minute cap paces the door so the origin sees a trickle instead of a stampede. A bot screen guards the line: real browsers queue normally, automation must solve a one-second proof-of-work, and hostile traffic — scanners, exploit probes, failed proofs — is held in a penalty box for a cool-off window. Signed-in teammates can skip the line.

In plain English — When your site is overloaded, extra visitors wait in a branded virtual line with an estimated wait instead of crashing your server.
