Best Virtual Waiting Room Software for JavaScript

A virtual waiting room is a page that holds visitors away from a busy website and feeds them back to the protected website at a rate it can handle while still maintaining responsiveness and performance. This means websites can handle unexpected or sudden peaks in traffic without website crashes, and without having to waste energy powering additional servers when things are not busy, so it's green tech too. Fair virtual waiting rooms pass visitors back in first-come, first-served order. A good virtual waiting room should also keep the visitor fully informed of their progress and remaining wait.

Protect your customers' goodwill with a smooth branded journey.
