Vulcan checks more: 25 of 47 kinds of cheats against 22 for GrimAC. But each covers something the other doesn't — see below.

GrimAC has it, Vulcan doesn't

  • NoFall — takes no fall damageVulcan, partly: no dedicated check — only a spoofed on-ground flag
  • Phase — walks through blocksVulcan, partly: no dedicated check, by their own page
  • NoSlow — no slowdown when eating or blockingVulcan, partly: only old sword-blocking, webs and honey — NoSlow while eating isn't detected
  • InvMove — moves with the inventory openVulcan, partly: undetected by their own page — only clicks while moving
  • NoRotate — ignores server rotation

Vulcan has it, GrimAC doesn't

  • KillAura — hits targets by itselfGrimAC, partly: no dedicated check — only indirectly, via Reach and packet order
  • Multi-aura — several targets in one tickGrimAC, partly: exists, but experimental — off by default
  • AimAssist / Aimbot — aims for the playerGrimAC, partly: only two rotation artifacts: a 360° snap and a repeated look
  • AutoClicker — clicks for the player
  • Criticals — crits without a real jumpGrimAC, partly: no dedicated check — only the generic on-ground check
  • Tower — pillars up faster than a humanGrimAC, partly: no dedicated check — only the generic jump simulation
  • FastPlace — places blocks too oftenGrimAC, partly: only several blocks in a tick, via an experimental check
  • Nuker — breaks everything around at onceGrimAC, partly: FastBreak limits the pace; the dedicated MultiBreak is experimental

Missed by both

Weak spots, from their own sources

GrimAC

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.

Vulcan

$19.99 per server. By its own page it targets “blatant cheaters who use common and publicly available hacked clients”; Phase, Blink, InventoryWalk and vanilla NoSlow are on its not-detected list.
