SkyBlock starts you on a small island in the sky with few resources, which you grow through farms, cobblestone generators, and trading. The Indonesian SkyBlock servers in this list have private islands, teams, and their own server economy. Check the online status and player count before choosing.
7 servers
Every SkyBlock server feels different: some are classic and slow, others are OP with spawners and minions for fast progress. Also check whether islands can be shared with friends and how island levels work.
SkyBlock almost always needs plugins, so it is a Java mode by nature. Some Indonesian servers also open Bedrock access through Geyser; look for the Bedrock tag on the server page.
