Chunkis

The Lean Storage Engine for Minecraft


📦 Tired of Bloated World Saves?

Minecraft is amazing, but the way it saves worlds is... heavy. Every single block, even thousands of "Air" blocks in the sky, takes up space on your hard drive. Over time, your world folder grows into a giant that's hard to backup and even harder to share.

Chunkis changes that.

✨ What is Chunkis?

Chunkis is a smart storage mod that fundamentally changes how your world is saved. Instead of saving everything, it asks a simple question: "Has the player changed this?"

If you haven't touched it, Chunkis doesn't save it. It simply lets the world generator handle it when you return.

🚀 Why you need it:

  • 💾 Massive Space Savings: Enjoy world files that are often 90% smaller than traditional saves.
  • ⏱️ Lightning-Fast Backups: Smaller files mean your server backups finish in seconds, not minutes.
  • ☁️ Easier Sharing: Uploading your world to a friend or a hosting provider becomes a breeze.
  • 💎 Bit-Perfect Accuracy: Every block you place, every item in your chests, and every sign you write is saved with 100% precision.

⚠️ Important: Beta Notice

Chunkis is currently in Beta. While we take data integrity very seriously and have tested it extensively, it is a significant change to how Minecraft handles your data.

  • Bugs are to be expected.
  • Single Player Only: Currently, Chunkis only supports Single Player worlds. Support for Dedicated Servers is coming soon!
  • Always keep a backup of your world before installing or updating Chunkis.
  • We recommend using it on new worlds or test servers first!

🛠️ How to use it

Just install the mod! Chunkis works silently in the background. It automatically takes over the saving process, ensuring your world stays lean and mean from the moment you start playing.

Compatible with Fabric 1.21.1+
