Best Minecraft Anticheat

Advanced Anti Cheat by consolas, dont know the newest version . But it is also very expensive

You can use Matrix. It's free and not bad. Should be ok for small server.

Premium AntiCheats like AdvancedAntiCheat, FIona are good, but have noname anticheats like NiroNoCheat are good too. NoCheatPlus good if if hands are not "crooked"

My server uses a private anti-cheat Advanced Anti Cheat (AAC)

A few years ago we thought "Watch Dog" (An anticheat created by the hypixel server) was good.
Now one of the best anticheats I would reccomend is "Anti Gaming Chair" or "AGC".

There is no good anticheats, all have some bugs, disadvantages and any cheat can broke its security

The best anticheat is a anticheat for 1.8 called sloth. There is a leak for it and it is amazing.

As I understand it, you want to use anti-cheat on your server.
Best to use NoCheatPlus.

NoCheatPlus, AdvancedAntiCheat, Spartan, TakaAnticheat, Reflex

Anyone share @ me how to get free world designs is that a thing? My kids play often
