Fabric support is currently in beta and is not production ready yet. Customers can get in touch on Discord to request the Fabric build, or you can self-compile.

This will walk you through installing HuskSync on your network of Spigot or Fabric servers.


Mixing and matching Fabric/Spigot servers is not supported, and all servers must be running the same Minecraft version.
Please also note some specific legacy Paper/Purpur versions are not compatible with HuskSync.
  • A MySQL Database (v8.0+)
    • OR a MariaDB, PostrgreSQL or MongoDB database, which are also supported
  • A Redis Database (v5.0+) — see FAQs for more details.
  • Any number of Spigot servers, connected by a BungeeCord or Velocity-based proxy (Minecraft v1.17.1+, running Java 17+)
    • OR a network of Fabric servers, connected by a Fabric proxy (Minecraft v1.20.1, running Java 17+)

Setup Instructions

1. Install the jar

  • Place the plugin jar file in the /plugins/ or /mods/ directory of each Spigot/Fabric server respectively.
  • You do not need to install HuskSync as a proxy plugin.
  • Spigot users: You can additionally install ProtocolLib or PacketEvents for better locked user handling.
  • Fabric users: Ensure the latest Fabric API mod jar is installed!

2. Restart servers

  • Start, then stop every server to let HuskSync generate the config file.
  • HuskSync will throw an error in the console and disable itself as it is unable to connect to the database. You haven't set the credentials yet, so this is expected.

3. Enter Mysql & Redis database credentials

  • Navigate to the new config file on each server (~/plugins/HuskSync/config.yml on Spigot, ~/config/husksync/config.yml on Fabric)
  • Under credentials in the database section, enter the credentials of your (MySQL/MariaDB/MongoDB/PostgreSQL) Database. You shouldn't touch the connection_pool properties.
  • Under credentials in the redis section, enter the credentials of your Redis Database. If your Redis server doesn't have a password, leave the password blank as it is.
  • Unless you want to have multiple clusters of servers within your network, each with separate user data, you should not change the value of cluster_id.
MongoDB users — additional instructions
  • Navigate to the HuskSync config file on each server (~/plugins/HuskSync/config.yml)
  • Set type in the database section to MONGO
  • Under credentials in the database section, enter the credentials of your MongoDB Database. You shouldn't touch the connection_pool properties.
  • Under parameters in the mongo_settings section, ensure the specified &authSource= matches the database you are using (default is HuskSync).

Additional setup for MongoDB Atlas

  • Set using_atlas in the mongo_settings section to true.
  • Remove &authSource=HuskSync from parameters in the mongo_settings.

(The port setting in credentials is disregarded when using Atlas.)

Pterodactyl self-hosts — Redis setup instructions

If you are hosting your Redis server on the same node as your servers, you need to use as your host (or equivalent if you changed your network settings), and bind it in the Redis config nano /etc/redis/redis.conf.

You will also need to uncomment the requirepass directive and set a password to allow outside connections, or disable protected-mode. Once a password is set and Redis is restarted systemctl restart redis, you will also need to update the password in your pterodactyl .env (nano /var/www/pterodactyl/.env) and refresh the cache cd /var/www/pterodactyl && php artisan config:clear.

You may also need to allow connections from your firewall depending on your distribution.

4. Set server names in server.yml files

  • Navigate to the server name file on each server (~/plugins/HuskSync/server.yml on Spigot, ~/config/husksync/server.yml on Fabric)
  • Set the name: of the server in this file to the ID of this server as defined in the config of your proxy (e.g., if this is the "hub" server you access with /server hub, put 'hub' here)

5. Start every server again

  • Provided your MySQL and Redis credentials were correct, synchronization should begin as soon as you start your servers again.
  • If you need to import data from HuskSync v1.x or MySQLPlayerDataBridge, please see the guides below:
