Cheat module compatibility
All 32 tracked cheat modules work on 1.21.1. See the full cheat database for module pages. Notable notes:
- Combat modules (KillAura, AimBot, Reach, TriggerBot, Criticals, Velocity) work with the 1.21 mace.
- Movement modules (Fly, Speed, BHop, Step, LongJump, NoSlowdown) work without version-specific adjustments.
- Visual modules (X-Ray, ESP, NameTags, FullBright, Tracers, Chams) render correctly with 1.21.1 terrain.
- World modules (Nuker, Scaffold, AutoMine, ChestStealer, FallProtection) work as expected.
Loader availability
- Fabric Loader — stable, widely tested.
- Forge — stable for 1.21.1.
- NeoForge — also available, but less common among clients.
Known limitations
- Trial chamber terrain is identical to 1.21 — X-Ray works but may miss ores behind trial chamber walls.
- Some Fabric utility mods built for 1.21.1 may not be compatible with later 1.21.x releases.
- Server anti-cheat behavior is version-independent — detection is based on behavior, not on the Minecraft version.
