Minecraft's vanilla entity system doesn't offer mod developers an easy way to attach and persist custom data on living entities — and that's exactly the gap Faux Custom Entity Data Mod fills. Acting as a lightweight API layer for the Fabric ecosystem, it lets other mods store arbitrary data on any in-game entity, keeping that data intact while the entity is alive and even saving it to disk for later retrieval. Player data persists across deaths, which opens the door for RPG-style progression systems, custom stats, and persistent quest tracking. Downloaded over 2 million times since its 2023 release, it has become a staple dependency in the Fabric modding community.
Key Features
- Custom entity data attachment — Provides a clean API for mods to bind custom data directly to any in-game entity, with that data preserved for the entity's entire lifetime.
- Persistent player data — Player-specific data survives death and respawn cycles, ensuring important information like quest progress or custom attributes is never lost.
- Automatic file serialization — All attached data is saved to disk alongside the entity's native data and restored seamlessly when the world is loaded again.
- Developer-friendly framework — Designed as a library mod, it handles the complex serialization and lifecycle management so other mod authors don't have to reinvent the wheel.

FAQ

On its own, this mod does nothing visible — it's a library that other mods depend on. You only need to install it if another mod in your modpack lists it as a required dependency.
Does Faux Custom Entity Data work with Forge or NeoForge?
No, this mod is built exclusively for the Fabric mod loader and requires Fabric API. There is no Forge or NeoForge version available.
