Fire Suppressing Cauldrons
by fastcall22
Fire Suppressing Cauldrons stops fire from spreading around cauldrons that players place, using a spherical effect centered on a cauldron, for Fabric servers.
What it does
Fire spread is checked by the server, and any cauldron the mod tracks keeps a suppressing effect around it. The effect is a sphere whose radius is set by the firesuppressor:max gamerule, and the mod hooks ServerLevel.canSpreadFireAround to run an extra check for cauldrons registered as points of interest. Cauldrons that are broken lose the effect, because the mod also hooks PoiManager.remove. Cauldrons moved by flying machines are accounted for within 8 ticks.
Because the mod runs only on the server, players join without installing anything. Its effect is mitigated by the fact that fire spread is relatively rare, so the performance cost stays small, though it is not zero. The mod is published for Fabric 1.21.11 – 26.3 and is released under the MIT License, so the source code is public and the issue tracker is open.
Key features
Cauldron fire suppression
Fire does not spread into the area around a cauldron, with the suppression range set through a gamerule.
Fill level control
The fill level of a cauldron controls the effect radius, so fuller cauldrons protect a wider area.
Broken cauldron cleanup
Breaking a cauldron removes its fire suppressing effect, so no protection lingers after it is gone.
Moved cauldron tracking
Cauldrons relocated by flying machines are picked up within 8 ticks and keep their effect.

Use cases
Protected cauldron hubs
Server owners can place cauldron clusters in a base or village so that fire from nearby sources does not burn into them.
Who it’s for: Server owners who run technical or survival worlds where fire spread is a concern, and who want cauldrons to be guarded without a client install.
How it compares
NoFireOnFire is a client-side only Fabric mod, open source under the MIT License, for 1.21.7 – 1.21.11, so it changes what players see rather than server fire behavior. BannerRetrieval is a server-side only Fabric mod under the Apache License 2.0, for 1.20.4 – 26.1.2, and it covers a different job. Fill My Cauldron is a server-side only Fabric mod under the CC0 1.0 Universal license, for 1.21 – 26.2, and it deals with filling cauldrons rather than fire.
