Minecraft 1.21 Compatible Servers FAQ
Common questions about finding and joining servers in this collection.
How do I join a Minecraft 1.21 server?
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.
Do 1.21 servers work with newer Minecraft clients?
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.
Why should I pick a server on the 1.21 line?
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 2,727 servers on this line, ranked by genuine activity.
