Open Persistence
Logging out of a Minecraft server used to be the safest thing you could do. You press the disconnect button, and your character simply vanishes into the void, invulnerable until you return. On survival or PvP servers, that safety net changes the entire dynamic of the game. What if your character stayed behind? What if the world kept spinning, and your gear remained at risk while you were away?
That is exactly the experience Open Persistence delivers. It is an open-source reimplementation of the classic Persistent Players mod, rebuilt for modern Minecraft versions with bug fixes and improved mod compatibility. When you log out of a multiplayer server, Open Persistence leaves behind a persistent body — an entity that looks exactly like you, holds all of your gear, and stands precisely where you disconnected. When you log back in, your state is transferred back to you, and the body is removed.
Why Logging Out Becomes a Real Decision
The core hook of Open Persistence is consequence. While you are offline, your body remains in the world. Other players or mobs can kill it. If that happens, your entire inventory drops on the ground, and your offline save data is updated so the loss sticks. This transforms logging out from a trivial action into a meaningful strategic choice on survival and PvP servers. Do you log out in your fortified base, or do you risk a logout in the open to save travel time?
Persistent Logout Bodies
When you leave the server, Open Persistence spawns a player-shaped entity. This body wears and holds your full inventory and equipment, visually mirroring your character. It is not a simple hologram or a placeholder — it is a physical entity that exists in the world and can be interacted with.
State Round-Trip on Login
When you rejoin, the mod performs a full state transfer. Your inventory, armor, and accessory slots are all restored from the body. Once the transfer is complete, the body despawns. The process is seamless, and you will find your character exactly as you left it — assuming nobody found you first.
Killable Bodies with Real Consequences
The body has its own health pool and can be slain. When killed, it drops your items and writes the change back to your offline player data. This is not just a visual effect; the loss is permanent and recorded. If you die while offline, you will log back in to find your inventory gone.
Built for Modern Minecraft
Open Persistence is a single multiversion project built using the Prism build system. It ships a separate jar for each Minecraft version and mod loader, ensuring you get the right file for your setup. The supported versions include Minecraft 1.12.2 for Forge, Minecraft 1.20.1 for both Forge and Fabric, Minecraft 1.21.1 for NeoForge and Fabric, and Minecraft 26.1 for NeoForge and Fabric. Loader versions are clearly documented, so you can match your environment precisely.
If you use the foxygame.net launcher, you can skip the manual file management entirely. The launcher's add-on catalog includes Open Persistence, and its one-click install handles version compatibility automatically, so you can get the right jar for your loader without digging through release pages.
Despawn-Proof Design
One of the most frustrating issues with persistent entity mods is that the game's own mechanics can remove them. Open Persistence is despawn-proof. The body will not vanish on peaceful difficulty, and it ignores the doMobSpawning gamerule and other mob-spawning disables. It also ignores despawn distance and persistence culling, so your body stays put no matter where you logged out or how far away you are.
Accessory and Extra Slot Support
Open Persistence does not just handle vanilla slots. It integrates with accessory mods as optional soft dependencies. On Forge and NeoForge, it supports Curios for versions 1.20.1 and later, copying items in Curios slots onto the body and restoring them on login. On the legacy 1.12.2 build, it preserves compatibility with the ModularWarfare (Shining fork) extra slots. On Fabric, accessory handling is a no-op, but the mod works fine without it.
Configuration Options
Server administrators have a few useful toggles to tailor the experience. The persistCreativePlayers option defaults to true, meaning even creative-mode players leave a body. Set it to false if you want creative players to log out safely. The offlinePlayersSleep option makes offline bodies lie down in a sleeping pose with a smaller hitbox, which can be useful for hiding or for roleplay servers. The debug option enables verbose logging for troubleshooting.
For those wondering how to install Open Persistence, the process is straightforward. Download the correct jar for your Minecraft version and mod loader, place it in your server's mods folder, and restart the server. No additional libraries or dependencies are required for the base functionality.
You can download Open Persistence from the official release pages or from the foxygame.net launcher, which also provides automatic updates so you always run the latest build. The mod is licensed under GPL-3.0, so it remains free and open for the community.
The Verdict
Open Persistence for Minecraft adds a layer of tension and realism that vanilla multiplayer lacks. It is not a mod for everyone — casual players may find the risk frustrating. But for survival servers, factions, and PvP-focused communities, it creates a persistent world where your absence has consequences. The implementation is solid, the compatibility is broad, and the despawn-proofing ensures the mechanic works exactly as intended. If you want logging out to mean something, this is the mod to use.
