tetra
by mickelus
Players who want tools and weapons that change over time can use Tetra, which lets equipment be modified with interchangeable parts.
What it does
Tetra lets players combine parts into tools, weapons and other equipment, and improve those items through use. Tool parts and schematics are found by searching ancient ruins, or obtained through trade and barter. The mod's two advancement tabs cover most of its content, and the holosphere shows stats for modules, improvements and materials.
Tetra requires mutil, which must be installed alongside it. Every player and the server need a copy of the mod. Files are published for Forge and NeoForge across four game versions, 1.19 – 1.20.1, and the code is covered by All rights reserved, so the mod is not open source. Curios compatibility is included for the toolbelt, and the author links an issue tracker for reports.

How it compares
Modular Weapons is open source under the MIT License and runs for Forge and NeoForge on 1.20.1 only. EC Create Compat is a Forge-only add-on for 1.20.1 under All rights reserved, and EC Advanced Netherite Compat covers Forge and NeoForge for 1.20.1 – 1.21.1 under the same license, so it reaches a wider range of versions than Tetra.
