Why Aegis

Engineered like a commercial anticheat.

The detections run on the network thread off real packet data, the same architecture used by industry-grade anticheats.

⚡

Packet pipeline

Movement, rotation, attack, swing and action packets feed a per-player state machine — processed off the main thread for zero TPS cost.

⏱

Latency compensation

A transaction (ping/pong) is sent every tick, giving an accurate per-player latency reading. Reach and timing checks compensate so laggy players aren't punished.

↩

Set-back engine

Illegal movement doesn't just get logged — players are rolled back to their last server-trusted position.

🖥

Built-in web panel

A dark dashboard for live players, violations, bans, announcements and a live config editor — served straight from the plugin.

🎯

Low false positives

Gravity-aware movement checks, rolling-average speed and zero-FP packet invariants keep legit players clear.

📦

Self-contained

PacketEvents is shaded and relocated inside the jar. Drop it in plugins/ and restart — nothing else to install.

📜

Punishment ladder

Each check builds a decaying violation level with its own alert and punish thresholds. Hit max VL and your command ladder fires — warn, kick, ban — with %player% %check% %vl% placeholders.

🎨

Make it yours

Brand the panel with your network's name and accent colour, secure it behind a token, and bind it to any host and port. Themed to match your server.

🛡

Staff-friendly

Clickable, hover-rich in-game alerts, a verbose mode for tuning, and an aegis.bypass permission so trusted staff are never touched.

Detections

Eighteen checks across four pipelines.

Each accrues a decaying violation level with configurable alert and punish thresholds — tuned for near-zero false positives.
