Our verdict

Strengths

  • Completely free, and you can inspect the code
  • An active repo (230+ stars, 400+ commits)
  • A good way to learn how detections work

Watch out for

  • Basic detection only: no aimbot or AI detection
  • The README points to the paid FiveGuard Premium for advanced features
  • Requires discord-screenshot and oxmysql
  • Client-side checks can be bypassed by experienced cheaters
  • AGPL-3.0: if you share a modified version, you have to share the source code too
