Anticheat comparison
GrimAC vs Polar: which anticheat is better
We checked 47 kinds of cheats against the source code and docs of GrimAC and Polar. Only a full check counts — "partly" and "indirectly" don't, and the rules are the same for everyone. DGuard is the third column.
GrimAC checks more: 22 of 47 kinds of cheats against 18 for Polar. But each covers something the other doesn't — see below.
GrimAC has it, Polar doesn't
- HitBox — enlarged hitboxesPolar, partly: not named — only the hit-distance check
- KeepSprint — sprint isn't reset after a hitPolar, partly: not named — only the generic movement simulation
- ElytraFly — controlled elytra flightPolar, partly: not named — the simulation recreates 'most' movements
- BoatFly / EntitySpeed — flies and speeds up on vehicles
- OmniSprint — sprints in any directionPolar, partly: not named — only the generic movement simulation
- FastBreak — breaks faster than possiblePolar, partly: not named — only a generic block-interaction check
- InvMove — moves with the inventory openPolar, partly: not named — only a generic inventory check
- Packet order in a tick — the cheat reorders actionsPolar, partly: not described — only a generic protocol check
- NoRotate — ignores server rotationPolar, partly: not named — only a generic protocol check
Polar has it, GrimAC doesn't
- KillAura — hits targets by itselfGrimAC, partly: no dedicated check — only indirectly, via Reach and packet order
- AutoClicker — clicks for the player
- Backtrack / FakeLag — hits past positions, holds packets backGrimAC, partly: no dedicated check — partly, via the experimental BadPacketsR
- Blink — holds packets, then teleportsGrimAC, partly: no dedicated check — partly, via the experimental BadPacketsR
- GhostHand — uses and hits through walls
Missed by both
20 of 47 kinds of cheats are checked by neither GrimAC nor Polar. DGuard has a check for every one.
Weak spots, from their own sources
Free and strong at movement. But it has no KillAura, Aim or AutoClicker checks — they're placeholders in its config, and heuristics are promised for a paid version that isn't on sale.
Movement and reach are never punished, there's no free tier, and it isn't sold in Russia or Belarus.
