Eslium
by Solmey
Eslium is a client-side prediction mod for Minecraft Java Edition that shows some server actions on the player's screen before the server confirms them.
What it does
Eslium predicts several outcomes on the client, so a player does not have to wait for server validation before seeing the result. The author describes the case of an end crystal: the crystal can be placed on obsidian or bedrock and appear immediately, and a minecart can be spawned on a rail as a predicted entity. The mod also covers actions such as firework rockets, the wind charge, entity poses and the lunge enchantment, which the author notes as part of the same predicted set.
The mod is aimed at players who experience latency on a server and want actions to feel responsive. The author states that the mod compensates for ping by fixing these predictions. Either side can run it, and neither needs it, so it works on a client alone, a server alone or both. Files target 1.21 – 26.3 across Fabric, Forge, NeoForge and Quilt, with snapshot builds published. The code is not open source and is released under the Creative Commons Attribution Non Commercial 4.0 license.
Key features
Predicted end crystals
Placing an end crystal on obsidian or bedrock shows the crystal before the server confirms the placement.
Predicted minecarts
Minecarts placed on rails appear as predicted entities, so the spawn does not wait for a server round trip.
Predicted combat effects
The lunge enchantment, firework rockets, the wind charge and entity poses are covered by the predictions.
Latency compensation
The author describes the predictions as a way to offset ping, aimed at players on higher-latency servers.

What the author says
Eslium is a project to predict more things client-side. For example, if you want to use a Crystal, you must wait for the server validation for it to appear. This mod fixes that and therefore compensates for the ping. When using any type of minecart on a rail, the spawn of the minecart is predicted
