Reviewed October 9, 2026. Hosting your own Minecraft Java Edition server can give friends a persistent world under your control, but it is not the same as joining a hosted Realm. The official downloadable server software is aimed at Java Edition, and beginners must account for compatible Java, world backups, memory, networking and security before sharing an address.
Quick answer: Download the Java server JAR from Minecraft’s official server download page, install the Java version required by that build, run it once, review and accept the EULA if you agree, then configure and test privately before exposing any network access.
Start with the correct product and account
Minecraft feature names may cover different editions and subscription products. Match the advice to the account, game edition and platform you actually use. Where the provider’s current screen disagrees with an old tutorial, the current official documentation and purchase terms take precedence.
Make sure your edition matches
The official server JAR on Minecraft.net is for Minecraft: Java Edition. Bedrock players use a different server package, and a vanilla Java server does not automatically allow cross-edition connections. Check each participant’s installed edition and software version before downloading. A mismatched client/server version can look like a network failure.
Download only the official server package
Visit minecraft.net’s Java server download page, read the version label, and save the JAR in a separate folder dedicated to one world. This reduces the chance of mixing the live server with random downloads. Do not use bundled launchers that ask for your Microsoft account password or promise paid hosting access at no charge.
Check Java and computer resources
Minecraft notes that running the downloadable Java server requires understanding Java from the command line. Install a Java runtime appropriate to the current server version using a trusted distribution. Start with reasonable memory limits that leave enough RAM for the operating system. The exact Java minimum can change with major game updates, so follow the downloaded version’s current requirements.
Run once and review the server files
Launch the JAR from a terminal in your server folder. The first attempt may generate an end-user license agreement file and configuration files; read the EULA and mark agreement only if you accept it. Preserve the server output if launch fails. Edit server.properties when the process is shut down, and keep the game mode, player limit and security settings intentional.
Test local play before internet access
Connect locally first, then invite a trusted friend through a safe network path. Router port forwarding may be necessary for direct hosting, but exposing your home connection has privacy and security implications. Avoid placing a public server address together with personally identifiable information. If you cannot administer firewall rules safely, a managed host or Realms may be preferable.
Back up worlds and maintain updates
Stop the server cleanly before copying world folders and retain independent backups outside the active server directory. When updating, read release notes, verify mod/plugin compatibility and keep a rollback copy. Don’t expect unofficial plugins from unknown pages to solve authentication or version mismatches securely.
Frequently asked questions
Does the free Java server work with Minecraft Bedrock?
No, not as a standard built-in feature. The official Java server package targets Java Edition clients.
Is downloading the Minecraft Java server software free?
The official server software download is available from Minecraft.net, but operating a computer and network may have costs.
Do I need to open ports to play on the same computer?
Not for an ordinary local test. Public connections may need carefully configured networking, depending on how you host.
