CrowdHandler is very easy to implement and very effective. The queue works very well. The interface is clear and intuitive. It only takes a few minutes to configure your domain and queue. The settings are both simple and sufficient for our needs. Works well with a SPA-type site. The pricing is suitable for our needs and the ability to suspend your subscription is a real plus.

I haven't found any major flaws, the solution perfectly meets my needs. Some customization options for the waiting page are missing in the Starter plan. Review collected by and hosted on G2.com.
