Chunk Tracker

Chunk Tracker is a client & server-side Fabric mod for Minecraft 1.21.1 that automatically logs every block in each chunk you load and alerts you when watched blocks appear nearby.

⚠️ Work in progress – bugs are expected.

Please visit my GitHub page to see my other mods and for sending bug reports, suggestions, and questions.

⛔ Server Warning — Chunk Tracker can make it easier to locate other players bases and structures. Always check the server rules and get permission from staff before using it, and never use it to harass or grief other players.

How It Works

Every chunk you load is automatically scanned and saved to a log file. You can search through your chunk history at any time and set waypoints to navigate back to specific blocks. If a watched block is found in a newly loaded or reloaded chunk, you'll get an in-game sound alert.

---

GUI

Open the GUI with /chunktrack gui or set a keybind in the settings menu.

🔍 Search Tab

Search your chunk history by block name; results update live and you can place waypoints on any result.

🔔 Alerts Tab

Shows chunks containing watched blocks and lets you waypoint them quickly.

🗺️ Biomes Tab

Lists discovered biomes; highlights borders and sets a waypoint to the center.

🏰 Structures Tab

Tracks structures along your journey and highlights their chunks. (Does not currently work on servers and only highlights one chunk)

🏷️ Renamed Tab

Shows chunks and biomes renamed with /chunktrack rename

🧾 NBT Hover Info

Hovering over blocks will show key NBT data in the tooltip (Only in the beta version 1.55), similar to Jade.
This includes things like:

• Items stored in containers
• Mobs configured in spawners
• Other relevant block entity data where available

---

Alert List

Add blocks to your watchlist and get a sound alert the moment they appear in a loaded chunk.
