About this Mod

Sessility is a Minecraft Fabric utility mod that keeps track of sessile creatures, more often known as "AFK players".

sessile

adjective

  1. (of an organism) permanently rooted in place; lacking mobility
  2. (of a plant) attached without a stalk

Feature summary

  • Change the color of sessile players in the player tab list
  • Exclude sessile players from the player sleeping requirement
  • Configure the amount of idle time before a player is considered sessile
  • Broadcast a chat message when a player becomes either sessile or motile
  • Hide sessile players in the player tab list, server player list, or server player count
  • Choose if player rotation should be used to determine motility

By default, any player idling for more than 120 seconds is considered sessile. Sessile players are given a distinct color in the player tab overlay to distinguish them from other players. The sessile idle time and tab display color are both configurable.

You can also configure custom messages when a player changes their sessility. These messages are disabled by default and will only display if a configured message is present.

Sessility also allows you to configure whether or not sessile players are displayed in the server player list (shown above), the server player count, and the player tab list. Each one of these properties can be toggled individually.

Frequently Asked Questions

Sessility server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.1.2). You can switch loaders with one click in the panel.

Is Sessility compatible with fabric?

Sessility officially supports fabric for Minecraft 26.1.2, 26.1.1, 26.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Sessility – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Sessility consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
