Head Index is an easy to user server-side head database mod for the Fabric Loader. Head Index provides easy access to over 36,000 heads provided by minecraft-heads.com. Unlike a plugin, Head Index can also be used in singleplayer without the need for a server. New heads are added all the time and will be automatically added whenever you restart the server without needing to update. Head Index also supports setting an item or economy (Common Economy API) cost for survival servers.
