Firestarter
by kadulous
Firestarter changes how fire spreads, so flames can reach and consume wooden structures far more readily than in vanilla.
What it does
Firestarter makes fire spread more aggressively, so wooden structures burn down much more readily. Its spread rules are set in a configuration file, letting server owners tune how far and how fast fire moves. Spread rules can also vary by biome, which lets one world keep damp areas safer than dry ones.
The mod can disable the spawning of fire pools, which reduces the number of natural wildfires in a world. Firestarter is server-side only, so players join without installing it, and the server needs Fabric API to run it. Files are published for Fabric only, for 1.20 – 1.21.11, with 2.0.0 for 1.21.11 as the latest file. The mod is released under CC0 1.0 Universal and is open source, with its source code, issue tracker and wiki publicly linked.
An older firespread.json5 file left from an earlier install may hold outdated values after an update, since the spread behavior was reworked. The author recommends deleting that file after updating, and the balance may need checking again. The author also notes that the mod is built to work with other mods that modify or use fire mechanics.
Key features
Aggressive fire spread
Fire spreads more readily to wooden blocks, so structures catch and burn faster than in vanilla play.
Configurable spread rules
A configuration file lets server owners change the spread rules without editing the code.
Biome-dependent spread
Spread rules can differ between biomes, so fire behaves differently in damp and dry regions.
Fire pool control
Spawning of fire pools can be disabled, reducing the number of natural wildfires that appear.

Use cases
Who it’s for: Server owners running Fabric who want fire to pose a greater threat to wooden builds. Players need nothing installed to join a server that runs it.
How it compares
Firesight is client-side only and runs under CC0 1.0 Universal, with files for 1.21.1 – 26.2, so it changes only what a player sees and does not affect server fire. Boom Control is server-side only, open source under the GNU Lesser General Public License v3.0 or later, and published for 1.19 – 1.20.1, a range that ends before Firestarter's versions begin.

What the author says
I recommend deleting this "firespread.json5" file if you had the mod installed before the v1.0.0 update, it is safe to do it anyway if you are unsure. This will make sure the mechanics are balanced again since in the v1.0.0 update I changed things around to allow for compatibility with other mods who modify/use fire…
