Can I run snapshots or a specific old version (1.8, 1.12.2, etc.)?

Whether you want a nostalgic 1.8 PvP server or a specific 1.12.2 modpack base, running older versions (and snapshots) is fully supported. Here's how.

Older versions and snapshots

Yes — the Versions tab lists many older versions and their builds; just pick the one you need. Older versions run fine — the main thing is to match your players' client version.

For snapshots or anything not listed, upload the JAR manually.

Step-by-step

1. Open the Versions tab and look for your version in the catalog.
2. Pick the version and build, and install.
3. For a snapshot or unlisted version, open Files, upload the JAR, and rename it to server.jar.
4. Start from the Console.

Tip: Make sure your players connect with the matching client version — an old server won't accept a newer client and vice versa.
