LagGuard is a next-generation anti-lag and redstone-protection suite engineered for modern Minecraft servers. It actively limits redstone updates, piston chains, hopper transfers, TNT explosions and entity spawns on a per-chunk basis, while an adaptive engine automatically tightens limits the moment your TPS starts to dip.
A modern boss-bar HUD keeps players informed of live performance metrics, and the dedicated staff radar instantly surfaces every detected lag source — complete with the exact player who placed the offending blocks and a one-click /lagsources GUI that teleports your team straight to the problem.
Built natively for Bukkit, Spigot, Paper, Purpur and Folia, fully compatible with MC 1.14 – 1.21.11, ships with 20 built-in languages, deeply customizable through a clean YAML config.
