PRAXIC AntiCheat
by jrxmod
PRAXIC AntiCheat is a Fabric server mod that checks player movement and combat, records violations and gives server staff a live incident feed.
What it does
Installation runs on the server only, so players need nothing extra, but the mod needs Fabric API on the server and is listed as requiring a client installation in its notes. Builds exist for 1.21.1 alone, with 0.17.0 as the latest beta file. The Apache License 2.0 covers the code, which is open source.
Each check has its own sensitivity, cooldown and response action, and can be switched off. Violations accumulate as evidence on a player profile, and points decay over time when no new flags arrive. A setback teleports a flagged player back to the last safe position instead of disconnecting them. REVEX can use the mod, and it is an optional dependency.
Key features
Movement physics prediction
The mod simulates vanilla gravity tick by tick and compares the predicted position with the actual one, catching fly and hover cases.
Combat and knockback checks
Knockback from explosions, wind charges and riptide is matched against the real impulse, so legitimate combat stays unflagged.
Violation decay and scoring
Violation points fall over time, and several checks are scored together, so a single isolated incident is not punished as heavily.
Live performance and incident feed
A live TPS and MSPT readout sits alongside an incident feed with flags, player profiles and quick actions for staff.
