Phantom Config
by IAmSneak
Phantom Config lets server owners change how phantoms spawn, from the sleep timer to the spawn rate and the biomes they appear in.
What it does
Phantoms are the flying mobs that appear to players who have gone too long without sleep. Phantom Config exposes the rules for that spawn as settings, so a server can make them less frequent, delay their first appearance, or limit how far from the player they can spawn. Each change is made in a configuration screen rather than in code.
The mod runs on Fabric and Forge and is server-side only, so players join without installing anything. On Fabric it needs Cloth Config API and Fabric API; on Forge it needs Cloth Config API. Files cover 1.16.4 – 1.20.4, and the latest Fabric file is 1.1.0+1.20.4 for 1.20.4 from 2023-12-14. The code is published under the MIT License and is open source.
Key features
Phantom spawn timing
Owners can set how soon phantoms start spawning after a player goes without sleep.
Spawn rate and count
The number of phantoms that can spawn and how often they try to spawn are both configurable.
Light and biome rules
Settings control the light level a player must be at for phantoms to spawn, and whether they spawn in mushroom biomes.
Distance limits
A distance setting controls how far from a player phantoms can spawn, reducing the nuisance on large worlds.

Use cases
Less intrusive phantoms
A server that finds phantoms disruptive can push their first spawn later and make them rarer.
Tuning for adventure maps
Map makers can adjust spawn light and biome rules to fit the layout and pacing of their world.
Who it’s for: Server owners who run survival worlds and want to adjust how often phantoms trouble players. Single-player players can also use it, since the mod only changes server-side rules.
How it compares
Sleep Tweaks is a Fabric mod for 1.21 – 1.21.11, released under the MIT License, and it works on either side, and neither needs it. Insomnia Tracker is a Fabric mod for 1.20 – 1.20.6, licensed under MIT-0, and both the client and the server must run it. Phantom Config differs in being server-side only on Fabric and Forge, with its own spawn settings and open source code.
