What is a CS2 radar?
A CS2 web radar is a second-screen overlay that shows live player positions, utility, and bomb state. Here's how it differs from the in-game minimap.

A CS2 radar - sometimes called a web radar or external radar - is a browser-rendered map view of a Counter-Strike 2 match. It updates in real time as the match progresses, showing where every player is, what they're holding, where the bomb is, and where smokes and molotovs have landed.
It runs outside the game, usually on a second monitor, a phone, or a tablet. The game itself doesn't render the radar - your browser does, talking to a service that receives the match state from a small client running alongside the game.
How it differs from the in-game minimap
CS2's built-in minimap (top-left HUD) shows:
- Your teammates' current positions
- Enemies only if a teammate has spotted them within the last second or two
- The bomb's location once it's planted
- Limited utility (the C4, your own grenades you've thrown)
A web radar removes those limits. It can show every player, every grenade, every smoke boundary, and every utility drop simultaneously. It can also include details the in-game radar doesn't have - distance, weapon, health, and the bomb carrier.
Why a separate screen
CS2 is competitive at high frame rates and benefits from a clean main display. A second screen keeps the radar large, glanceable, and out of the game's HUD. Most users put it on a phone next to the keyboard, on a small tablet, or on a secondary monitor.
What the radar surface shows
- Map geometry - accurate top-down map outline with callout regions.
- Players - coloured dots or icons with names, weapons, and direction indicators.
- Bomb - separate icon while it's being carried, planted, or being defused.
- Smokes / molotov / decoy / flash - actual area of effect, not just the throw point.
- Latency - how stale the displayed state is, in milliseconds.
How it relates to ESP
A radar is one form of ESP - Extra Sensory Perception, the umbrella term for any system that surfaces game data the player wouldn't normally see. Boxes drawn around enemies through walls are ESP; so is a radar. Favade combines both: the top-down radar surface plus optional ESP-style annotations on the same screen.
