Pyre
by earlystream
Pyre is a Fabric optimization mod that reduces stutter during heavy TNT explosions in integrated-server play, and it is not a general performance tool.
What it does
Pyre optimizes a selected set of explosion-related workload paths so that repeated work during bursts of explosion events is reduced. The mod concentrates on chained TNT blasts, where it works to make a run of explosions feel smoother while leaving the way vanilla blasts behave largely as it is.
The mod is described by its author as an experimental Minecraft optimization for singleplayer and integrated-server use on Minecraft 1.21.11. It is an alternative to general optimization mods such as Sodium, Lithium and FerriteCore only in the narrow sense of explosion handling; it does not replace them for other workloads. Pyre needs Fabric API, and it runs on client and server, so both the server and every player need it.
Builds cover 1.21 – 1.21.11 across 12 release versions, and the mod is released under the Mozilla Public License 2.0 as open source. Its source code and issue tracker are public.
Key features
Explosion workload reduction
Reduces some overhead during heavy explosion activity by skipping unnecessary repeated calculations in bursts.
Chained TNT focus
Targets scenarios with many TNT blocks igniting in sequence, where stutter is most noticeable.
Vanilla-close behavior
Keeps explosion power, fuse time, damage, knockback and block destruction close to vanilla behavior.
Lightweight implementation
Changes are kept small and limited to selected explosion paths, with balance left as it is in the base game.

How it compares
Xodium is client-side only, not open source and published for 1.21.11 under All rights reserved. FastTNT is server-side only, under the MIT License, and also published for 1.21.11 only. Useful TNT is client and server, open source under the CC0 1.0 Universal license, and covers 1.21.10 – 1.21.11. Pyre is client and server, open source under the Mozilla Public License 2.0, and covers 1.21 – 1.21.11, so it has the widest version range of these options.
