Sonar
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Sonar is a lightweight, effective and easy-to-use antibot plugin for Velocity, BungeeCord, and Bukkit. Sonar provides a multi-layered defense against bots, keeping your server safe from common and even sophisticated bot attacks.
