How to join a Minecraft server

Frequently asked questions

Which mods do I need to install?

Read the exact mod list and versions. Follow the server’s instructions: a compatible game version may not be enough if your installation uses different content.

Can I join with Java or Bedrock?

Check the editions on the listing. A Java address alone is not enough to join from Bedrock. If both editions are supported, use the address and, for Bedrock, the port for your edition. Use Minecraft Java and check the required version or modpack before copying the address. The listing shows version 1.21.1; check required mods and joining instructions too.

How are servers listed and checked?

The selected sort determines the listing order. Online player counts come from status queries, without votes or paid ranking. The map shows an estimated connection IP country. Language filters use operator declarations, server settings and text, or information from the official website. The source is shown on the listing. Machine country does not determine the in-game language.
