  ### 6. [Queue-it](https://www.g2.com/products/queue-it/reviews)
By Queue-it
**Average Rating:** 4.7/5
**Total Reviews:** 161
Queue-it helps in high-demand and limited-supply situations—like sneaker releases, ticket on-sales, or government registrations—that can easily overwhelm a website or app. In these high-demand situations, online visitors are redirected to a customizable waiting room and then throttled back to the website or app. In the case of scheduled sales or registrations, organizations can create a scheduled waiting room that holds early visitors on a countdown page and randomizes them just like a raffle once the sale or registration begins, giving everyone an equal chance. Later visitors are then added to the end of the line on a first-come, first-served basis. Queue-it's virtual waiting room can also guard against traffic overload 24/7, working as a safety net by constantly monitoring traffic inflow and only activating the waiting room when traffic exceeds the configured thresholds. By controlling online traffic, Queue-it's virtual waiting room lets organizations control their online experience. They capture sales, deliver seamless user experiences, ensure fairness, and protect brand reputation.
