Whitelist Sync 2

by PotatoDotJar

Whitelist Sync 2 keeps the whitelists, operator lists and ban lists of several servers aligned through one shared self-hosted database.

What it does

The mod reads and writes the server whitelist, the ops list, banned players and banned IP addresses. Several Minecraft servers can point at one MySQL or SQLite database, so a change made on one server reaches the others. A companion Whitelist Sync Web service is available for those who prefer a hosted option, and its subscribers take priority over the self-hosted database when both are in use.

Setup starts by placing the mod in the mods folder and running the server once to create its configuration file, whitelistsync.cfg or whitelistsync-common.toml, in the config folder. The database address, port and authentication go in that file, along with the sync timer. Existing whitelists can be pushed to the database with copyServerToDatabase, and the mod then polls the database at an interval set in the config to pull changes. Fabric API is required, and the mod supports servers running in offline mode.

Whitelist Sync 2 is server-side only, so players join without installing anything. It is released under the GNU General Public License v3.0 only, is open source, and is published for Fabric, Forge and NeoForge with files for 1.12.2 and 1.16.5 – 26.2. The 1.12.2 line is no longer supported, and versions before 1.16.5 are handled only on request.

Key features

  1. Shared ban lists

    Banned players and banned IP addresses are synced across every server that connects to the same database.

  2. Operator list sync

    The ops list is kept in step between servers, so an operator added once is recognized everywhere.

  3. Polling updates

    Local whitelists and ops lists refresh by polling the database at a configurable interval.

  4. Existing whitelist import

    A current server whitelist can be pushed into the database with copyServerToDatabase, then pulled back into other servers.
