What is Radar in Minecraft?

Radar is a module found in some Minecraft clients that draws a top-down minimap overlay showing where nearby players and entities are relative to you. Instead of rendering full entity models through walls like ESP does, Radar abstracts that same awareness down to a scatter of dots: direction, distance, a position marker. You get a warning that someone is closing in from around a corner or climbing up from beneath you, without the visual clutter of watching bodies clip through terrain. It reads like sonar, which is exactly why players like it and exactly why servers don't.

How Radar works

Every entity near you already has a position the server tracks and sends to your client. That's how normal rendering works, how hit detection functions, how the tab list gets populated. Radar takes that same position data and plots it as a dot on a flat overlay instead of feeding it only into the normal, occlusion-respecting 3D render.

The overlay is typically oriented either north-locked or facing-relative. In north-locked mode, dots stay put on the compass. In facing-relative mode, they rotate with your camera direction. Either way, the module never asks the server for anything a vanilla client wouldn't receive. It just visualizes information that's normally invisible to you.

Radar vs. ESP

These two get compared constantly, and they deserve to be. Both give you awareness of entities you can't normally see. They approach it differently.

Radar condenses the awareness down to pure position. ESP lets you see a complete entity model through terrain, which can feed aim modules and combat tracking. Radar is the subtler play.

Why servers ban it

Most competitive servers don't ship a Radar module and don't allow it. The reason is straightforward: it grants awareness no vanilla player gets. A player running Radar knows someone is approaching before they hear footsteps or see a nametag. That's an informational edge, and server policy doesn't usually carve out exceptions for edges that are hard to detect.
