Custom Cartesians
Sharing your coordinates in Minecraft is a double-edged sword. It helps friends find your builds, but it also hands strangers a map straight to your base. Custom Cartesians is a client-side Fabric mod that solves this problem by letting you control exactly which coordinates appear on your screen. Instead of broadcasting your full position to anyone watching your stream or screenshots, you decide what stays visible and what stays hidden.
What Custom Cartesians Does
At its core, Custom Cartesians adds a lightweight coordinate display HUD that sits on top of your game. Unlike the vanilla F3 debug screen, this overlay is fully configurable. You can choose to display only the X axis, only the Y axis, only the Z axis, or any combination that suits your playstyle. That flexibility is what makes it genuinely useful rather than just another cosmetic add-on.
The HUD is designed to be non-invasive. It automatically hides itself whenever the vanilla debug screen is open, so you never end up with overlapping information cluttering your view. If you want it gone entirely for a while, a quick keybind toggles the whole overlay off without digging through menus.
Key Features at a Glance
- Customisable coordinate HUD with per-axis toggles
- Overlay hides automatically when the vanilla F3 screen is active
- Full toggle support through keybinds or config
- Config file stored in minecraft/config/customcartesians/client.toml
- Compatibility with Cloth Config and Mod Menu
- Keybind actions sync directly to the config file
Supported Versions and Loader
Custom Cartesians is built for the Fabric loader and requires the Fabric API to run. Cloth Config API is also required, though it comes preinstalled with the mod, so you do not need to hunt it down separately. Mod Menu is optional but highly recommended if you prefer adjusting settings through an in-game GUI instead of editing files by hand. The mod is client-side only, which means it should never be installed on a dedicated server. Forge support has been mentioned as a future possibility, but Fabric is the current home for this add-on.
If you use the foxygame.net launcher, grabbing Custom Cartesians is refreshingly simple: the launcher's add-on catalog handles the one-click install and keeps the mod updated automatically whenever a new build drops. That means fewer version mismatches and more time actually playing.
How to Install Custom Cartesians
Getting the mod running takes only a few minutes. Follow these steps to download Custom Cartesians and set it up correctly.
- Install the Fabric loader for your Minecraft version if you have not already.
- Download Custom Cartesians from its official CurseForge page or GitHub repository.
- Place the mod jar file into your mods folder.
- Confirm that Fabric API is present, since the mod will not load without it.
- Optionally add Mod Menu if you want an in-game configuration screen.
- Launch the game and verify the mod appears in your mod list.
Remember that this is a client-side mod. Installing it on a server does nothing useful and may cause confusion, so keep it in your local instance only.
Configuring the Overlay
There are two ways to configure Custom Cartesians. The first is through the config file located at minecraft/config/customcartesians/client.toml. Open it with any text editor, set the "toggleOverlay" option to true, and save the file. The second method is far more convenient: if you have Mod Menu installed, go to Mods, select Custom Cartesians, and click the Configure button. Adjust your settings and hit "Save and Quit" when you are done.
Keybinds offer the fastest control of all. Hold down the "Mod Base Setting" keybind, then press the corresponding key for the coordinate you want to toggle. By default, holding Left ALT and pressing H toggles the Y coordinate display. Once you learn the pattern, switching axes on the fly becomes second nature, and every change is written straight back to the config file.
Who Should Use This Mod
Custom Cartesians is aimed at players who share their gameplay publicly. Streamers, content creators, and anyone posting screenshots on forums or social media will appreciate the ability to hide sensitive coordinates without losing navigation entirely. Survival players who want a cleaner alternative to the bulky F3 screen will also find plenty to like here.
The planned additions, such as movable HUD positions and optional extra information fields, suggest the mod will only grow more flexible over time. For now, it does one job and does it well: giving you precise control over what the world sees of your position.
Final Thoughts
Custom Cartesians is a small mod with a clear purpose. It respects the vanilla experience, integrates cleanly with popular configuration tools, and solves a real problem for anyone who values a bit of privacy in their Minecraft world. If you have ever hesitated before sharing a screenshot because your coordinates were on display, this add-on is exactly what you need.
