As of 1.21.2, this plugin is no longer needed. Simply configure pause-when-empty-seconds in your server.properties file instead.
This plugin stops the server tick when the last player disconnects, and starts ticking again automatically when a player joins the server. This can save server resources in some cases, especially if you have a lot of spawn chunks or force-loaded chunks.
As opposed to other solutions, plugins like Dynmap will continue working and no "Can't keep up" messages will be shown. FreezeHibernate also does not require multiple connection attempts to unfreeze the server.
This uses the new tick debugging feature introduced in 1.20.3/1.20.4, and as such will not work on versions older than 1.20.4.
There are no commands or configuration files. If you wish to unfreeze or freeze the server manually, you can use the vanilla command.
