Simple AntiAFK
by Magnus_Dux
Simple AntiAFK is a lightweight NeoForge client mod that keeps a player from being kicked for idling.
What it does
Servers commonly remove players who stay idle for too long. Simple AntiAFK simulates player activity so that the server does not mark the session as inactive. Only the client needs the mod, so servers run without it. The mod targets NeoForge for 1.21.1 only, and its single file, 1.0.0, was published on 2026-02-08 under the MIT License, which is not open source.
Key features
Simulated activity
Periodic input is generated on the client so the server sees the player as active and skips the idle kick.
Works while idle screens are open
Activity is still simulated while the inventory, chat or ESC menu is open, or while the game window is minimized.
Lightweight design
The mod is small in scope and does one job, preventing AFK kicks, without adding other gameplay systems.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
