The use case is a simple way to create websites that fall into one of the defined site types.
Say you want to create an event page it is very simple to follow the builder and to create a link for an event that you can share. The link contains all the data for the event and your actual event data is never sent to a server. This makes creating the event private and also means the link can’t be removed.
There are 8 different site types that you can follow the online builder to make and try out. 5 of the sites are contained fully in the link and 3 use nostr for communication. The one that relies on nostr the most is the forum which lets you create a private forum that you can share with friends.
