OpenCombatUtility (OpenCU)
OpenCombatUtility, abbreviated OpenCU, adds automated combat and utility blocks to Technology play through a modular dispenser and a set of pulse-based devices.
What it does
The mod centers on a modular dispenser that can be assembled from a modular frame and extended with add-on modules. Its pulse devices, such as the Repulsor and the Vector Pulse, push, pull, move or slow entities in an area, which makes the mod suited to automated PvE and PvP setups. A dispenser built this way behaves like a vanilla dispenser or dropper, with the added options the modules provide.
The mod requires CC: Tweaked, QuLib and oωo (owo-lib) on every loader, so all three must be installed beside it. CC: Tweaked is also optional, and when present, its devices can be used alongside the redstone-driven parts of the mod. OpenCU runs on client and server, and the server and every player need it. Files are published for Fabric and Forge across three game versions, 1.12.2, 1.18.2 and 1.19.4, under the MIT License, and the project is open source with a public API on GitHub.

How it compares
KubeVS is an option for Fabric and Forge on 1.18.2 – 1.20.1, released under the Apache License 2.0 and open source, where it is client or server optional. Some Peripherals is a Fabric and Forge mod for 1.18 – 1.18.2 that is client and server and released under the MIT License, so it covers the same versions as OpenCU's 1.18.2 build and shares its license. PvE is server required and client optional, with Fabric files for 1.21 – 1.21.8 under All rights reserved, so it reaches versions OpenCU does not target.
