WAT - Where are they? Player Tracking Add-on for Minecraft
Ever wondered where everyone on your server actually disappears to? WAT - Where are they? is a lightweight tracking mod that quietly records the position of every connected player and writes those coordinates into a text file. Those logs can then be loaded into the Player Tracker Decoder, a companion application that turns raw numbers into interactive maps you can pan, zoom, and analyze. If you run a busy survival world or a sprawling SMP, this is one of the most practical admin tools you can add to your setup.
What Does WAT - Where are they? Actually Do?
At its core, the mod samples player positions at a configurable interval measured in ticks and appends them to a log file. There is no database, no cloud service, and no hidden telemetry. The notice from the developer is clear: only connected player names and positions are recorded. Nothing else is collected, and no data leaves your machine. That makes it a privacy-friendly option for server owners who want insight without surveillance bloat.
The real magic happens when you pair the log with the Player Tracker Decoder. On its own, a wall of timestamps and coordinates is hard to read. Inside the decoder, the same data becomes a heatmap of activity, showing where players cluster, which bases get the most traffic, and the exact routes they take across the overworld, Nether, and End.
Client vs Server: Which Version Should You Use?
The mod runs on both sides, but the experience is very different.
- Client install: Tracks only rendered players, so range is limited and you only see the dimension you are currently standing in.
- Server install: Tracks all players across all dimensions, giving you a complete picture of your world.
For serious analysis, the server side is the clear winner. A client setup is fine for personal curiosity, but if you want to understand server-wide behavior, install it on the server itself.
Supported Versions and Loaders
WAT - Where are they? is built for modern Minecraft releases and is distributed for both Fabric and Forge, so most current modpacks will accept it without complaint. If you use it on the client, ModMenu integration lets you tweak the logging rate on the fly; otherwise, you can edit the config file directly. The logging interval is fully adjustable, which means you can log every few ticks for detailed path data or slow it down to keep file sizes manageable on long-running worlds.
Before you commit, check the exact game version listed on the project page. Loader compatibility shifts between major updates, and matching your Fabric or Forge build to the right release saves a lot of headache later. If you would rather skip manual file juggling entirely, the foxygame.net launcher bundles WAT - Where are they? into its add-on catalog and handles version matching automatically, so the correct build lands in your instance with a single click.
How to Install WAT - Where are they?
Installation is straightforward for anyone who has added a mod before.
- Confirm your Minecraft version and whether you run Fabric or Forge.
- Download WAT - Where are they? from the official project page.
- Drop the jar file into your mods folder.
- Launch the game once to generate the config, then adjust the tick rate to taste.
- Install the Player Tracker Decoder separately to read and visualize the logs.
On a server, place the jar in the server mods directory and restart. Logs begin writing as soon as players connect, and you can pull the file at any time without stopping the server.
A Warning Worth Repeating
Do not use this on servers where you lack permission. Tracking other players without consent can get you banned, and rightly so. Use it on your own server, on a private world, or anywhere you have explicit approval from the owner.
Why Server Admins Keep Coming Back
Griefing investigations, activity reports, and map design all benefit from hard positional data. Instead of guessing where a raid started, you can replay the path. Instead of wondering whether a region is abandoned, you can check the heatmap. The companion decoder even exports the data, which is handy for community write-ups or moderation records.
For players who want the same convenience on a single machine, the foxygame.net launcher keeps WAT - Where are they? updated alongside your other mods, which means no more hunting for the right build after every game patch. Download WAT - Where are they? once, configure your tick rate, and let the logs do the rest. Whether you are chasing a mystery or mapping a megabase, this mod turns scattered coordinates into a story you can actually follow. ===ARTICLE===
