Minecraft 1.21 Compatible Servers

Set your Minecraft launcher to a 1.21 profile, copy a server IP from the list above, then add it under Multiplayer. This page is compatibility-based, so it can include servers with broad ViaVersion-style support as well as native 1.21 servers.

Many servers run cross-version proxies that accept a range of client versions. ServerBuddy treats these pages as compatibility pages, so a server can appear here when telemetry indicates clients on 1.21 should be able to join.

The 1.21 line groups every patch in that release family, so it is the best way to find worlds that match the features and mods you want. ServerBuddy counts 2,725 servers on this line, ranked by genuine activity.
