WordPress multisite is a feature in WordPress that allows users to create a network of multiple websites that share a common installation of WordPress. This feature allows the entire website in the network to be managed from a single set of login credentials.

Multisite feature can be very useful for organizations or individuals who need to manage multiple websites or blogs.

One major limitation of WordPress Multisite is that the database tables keep getting longer with more sites being added to the multisite network.
