GrimAC
Fully async, multithreaded, predictive, open source, 3.01 reach
GrimAC is an open-source anticheat system designed to detect and prevent cheating on Minecraft multiplayer servers through predictive simulation and advanced movement analysis. The project uses a simulation-based detection engine that recreates player movement and physics in order to identify discrepancies between legitimate gameplay and modified client behavior. By analyzing how players move, interact with the world, and send network packets to the server, Grim can detect a variety of cheats such as reach hacks, speed hacks, and anti-knockback modifications. The software is designed to operate asynchronously and with multithreaded processing, allowing servers to maintain high performance even when monitoring large numbers of players simultaneously. Grim supports a wide range of Minecraft versions and can integrate with server platforms used in competitive or large multiplayer environments. -

Purpur
Purpur is a drop-in replacement for Paper servers
Purpur is an open-source Minecraft server software built as a fork of the Paper server platform, designed to provide extensive configurability and gameplay customization for server administrators. It functions as a drop-in replacement for Paper, meaning existing servers can switch to Purpur without major changes while gaining access to additional features and configuration options. The project focuses on allowing administrators to modify gameplay mechanics, behaviors, and rules that are normally fixed in standard server implementations. Through a wide set of configuration settings, server operators can adjust how mobs behave, alter game mechanics, or enable experimental gameplay features that are not present in vanilla Minecraft. Purpur inherits performance improvements and plugin compatibility from the Paper ecosystem while adding its own enhancements and customization capabilities. -

Project Malmo
A platform for Artificial Intelligence experimentation on Minecraft
How can we develop artificial intelligence that learns to make sense of complex environments? That learns from others, including humans, how to interact with the world? That learns transferable skills throughout its existence, and applies them to solve new, challenging problems? Project Malmo sets out to address these core research challenges, addressing them by integrating (deep) reinforcement learning, cognitive science, and many ideas from artificial intelligence. The Malmo platform is a sophisticated AI experimentation platform built on top of Minecraft, and designed to support fundamental research in artificial intelligence. The Project Malmo platform consists of a mod for the Java version, and code that helps artificial intelligence agents sense and act within the Minecraft environment. The two components can run on Windows, Linux, or Mac OS, and researchers can program their agents in any programming language they’re comfortable with. -

Minestom
1.21.11 Lightweight Minecraft server
Minestom is an open-source Minecraft server development framework that allows developers to build custom Minecraft server software from scratch without relying on Mojang’s original server code. Instead of functioning as a traditional server implementation, Minestom acts as a lightweight library that provides the core networking and gameplay infrastructure needed to create Minecraft server applications. Developers can use it to design custom game modes, experimental server architectures, or entirely new gameplay systems while maintaining compatibility with the Minecraft Java Edition client. The framework focuses on performance, modularity, and extensibility, allowing developers to include only the features required for their specific server projects. Because Minestom is designed with a minimal base architecture, it enables high performance and easier scalability for custom server environments. -

Create
Building Tools and Aesthetic Technology
Create is a large Minecraft modification that introduces mechanical engineering systems, automation tools, and kinetic machinery into the game. The mod focuses on building complex contraptions powered by rotational energy rather than relying on traditional redstone circuitry alone. Players can design elaborate machines using components such as shafts, gears, belts, and mechanical devices that interact with each other to automate crafting, farming, and resource processing. Unlike many technology mods that rely heavily on graphical interfaces, Create emphasizes visible mechanical movement and physical machinery that operates directly in the game world. The mod also includes a visual documentation system called “Ponder” that demonstrates how each machine or component works through animated tutorials inside the game. -

FarPlaneTwo
Level-of-Detail renderer in Minecraft. Allows for render distances
FarPlaneTwo is an experimental open-source Minecraft mod that introduces a Level-of-Detail (LoD) terrain rendering system designed to dramatically extend how far players can visually see across the game world. Instead of rendering distant terrain using the same detailed chunk system as nearby areas, the mod generates simplified representations of terrain that require far fewer resources to display. This approach allows players to view landscapes at extremely large distances while maintaining acceptable performance levels. The project aims to support render distances far beyond the limits of the standard Minecraft engine, potentially reaching hundreds of thousands or even millions of blocks. By creating progressively lower-detail versions of terrain farther from the player, the mod can display the shape and structure of distant regions without fully loading those chunks. -

Botania
A tech mod for Minecraft themed around the magic of nature
Botania is a Minecraft tech mod themed around natural magic. It's inspired by other magic mods, such as Thaumcraft or Blood Magic. With an original aim- and timing-based power system, Botania has a very different feel from your typical magic or tech mod. Manipulating Mana and watching it flow in real time adds a new light to your base of operations. Botania works within the Minecraft world itself; no GUIs are used to interact with any of its features. It's carefully designed to ensure that nearly everything is fully automatable using vanilla and itself. After some thought, of course. The Lexica Botania is the compendium of nearly all knowledge about this mod. Easily craftable in-game using a book and a sapling, it gives you almost all the information you'll ever need to know about Botania. -

Luck Perms
A permissions plugin for Minecraft servers
LuckPerms is a widely used open-source permissions management plugin for Minecraft servers that allows administrators to control what actions players can perform within the game. The plugin provides a flexible system for creating user groups, assigning permissions, and defining roles that determine access to commands, features, and gameplay mechanics. Designed for performance and scalability, LuckPerms can handle large multiplayer servers and complex permission hierarchies while maintaining fast response times. Administrators can configure permissions using command-line tools, configuration files, or a web-based editor that simplifies management of large permission systems. The plugin also supports multiple storage backends such as local files, SQL databases, and other data systems, allowing server networks to synchronize permissions across multiple servers. -

Phosphor (for Fabric)
A Fabric mod designed to improve the performance of Minecraft
Phosphor is a free and open-source Minecraft mod (under GNU GPLv3) aiming to save your CPU cycles and improve performance by optimizing one of Minecraft's most inefficient areas-- the lighting engine. It works on both the client and server and can be installed on servers without requiring clients to also have the mod. The mod is designed to be as minimal as possible in the changes it makes, and as such, does not modify the light model or interfaces of vanilla Minecraft. Because of this, Phosphor should be compatible with many Minecraft mods (so long as they do not make drastic changes to how the lighting engine works.) If you've ran into a compatibility problem, please open an issue. -

Starlight Fabric
Rewrites the light engine to fix lighting performance
Starlight is a performance optimization project for Minecraft that completely rewrites the game’s internal lighting engine to improve efficiency and reduce lighting-related lag. The original Minecraft lighting system can be computationally expensive when generating terrain or updating large structures, which can cause performance problems on servers and heavily modded environments. Starlight replaces this system with a redesigned algorithm that processes lighting calculations more efficiently and reduces the number of updates required for each chunk. The project aims to improve chunk generation performance, reduce lag spikes, and eliminate certain lighting bugs that occur in the vanilla engine. Because it fundamentally replaces the default lighting system, Starlight can significantly improve performance on servers handling large numbers of block updates or terrain generation tasks. -
