HCsCR
by VidTu
HCsCR is a client-side crystal optimizer for Crystal PvP that removes end crystals from the client before the server registers a hit.
What it does
Crystal PvP fights depend heavily on client ping, because each crystal placement and hit has to travel to the server and back. HCsCR works on the player's own client to reduce that delay, so crystals and anchors react closer to the moment the player acts. The mod is a client mod: servers run without it, and players who install it join a server as usual.
The mod targets end crystal and respawn anchor combat. Its author notes describe it as more configurable than other client crystal optimizers, while noting that a server-side plugin would be more effective, since the server can enforce the change for every player. Installation needs Fabric API on every supported loader, with Mod Menu as an optional companion for its settings screen.
HCsCR is published for Fabric, Forge, NeoForge and Quilt. Builds cover 1.16.5 – 26.3, with snapshot builds published as well, and the latest file is 2.1.13+26.3 for 26.3. The code is open source under the Apache License 2.0.
Key features
Client-side crystal removal
The mod removes end crystals on the client first, so the result shows up without waiting for the server's reply.
Configurable behavior
Several settings control how the optimizer acts, and Mod Menu can open the settings screen when it is installed.
Crystal spam handling
The optimizer is aimed at rapid crystal placement, which is where the ping delay has the largest effect in combat.

Use cases
Who it’s for: Players who fight in Crystal PvP on servers that allow client-side changes will get the most use from this mod. Server owners who want the change enforced for everyone may prefer a server-side plugin instead.
How it compares
Fast Crystal is a Fabric-only client mod under the MIT License, covering 1.19 – 26.3, and it is not open source. Shikaru's Crystal Optimizer is also a client-side Fabric mod, released under the MIT License and open source, but its range is narrower, 1.21.11 – 26.2. Simple Crystal PVP Disabler works from the server side, so it is the option when a server operator wants to limit crystal combat for all players.

What the author says
Remove your end crystals before the server even knows you hit 'em! (a "crystal optimizer") Crystal PvP ("cpvp") has become a pretty popular combat mode in Minecraft. Crystals themselves were never designed to be used in combat. Because of this, a client ping (latency) plays a significant role in a crystal PvP fight…
