ClientReflex (Fabric)
ClientReflex is a client-side mod for Minecraft that improves the multiplayer experience on servers with lag, high ping, or unstable connections. It optimizes how the client handles networking to reduce disconnections and make gameplay feel more responsive—without modifying the protocol or cheating.
Features
- Anti-disconnect system for micro network drops
- Intelligent auto-reconnect
- Network HUD with real-time ping, jitter, and statistics
- Packet prioritization (movement, attacks, block placement)
- Safe visual prediction (crystals, beds, anchors, TNT minecarts)
- Input smoothing and player interpolation
- Automatic render adjustments based on ping
- Netty optimizations (TCP_NODELAY, SO_KEEPALIVE)
Information
- Client-side only (no server required)
- Safe and compatible with anti-cheats
- Fully configurable (ModMenu optional)
- Minecraft 1.21.x · Fabric
- Packet Prioritization: Gives priority to critical packets such as movement and attacks.
Requirements
- Fabric Loader >= 0.15.0
- Fabric API (any version)
- Minecraft 1.21.x
- Java >= 21
Optional Dependencies
- ModMenu 7.2.2+ (for in-game configuration)

ClientReflex does not reduce your real ping; it improves perceived latency and gameplay stability.
