NeoForge is an open-source modding API and mod loader designed for Minecraft: Java Edition that enables developers to create and run game modifications within a structured development framework. The project was created as a community-driven continuation of the Minecraft Forge ecosystem and aims to provide a modernized, actively maintained platform for mod development. NeoForge includes tools, APIs, and build systems that allow developers to modify game behavior, add new gameplay mechanics, and integrate custom content into Minecraft worlds. The framework is designed to simplify the development process by offering standardized interfaces, development kits, and compatibility layers that help mod creators build complex modifications without rewriting core game code. By supporting mod development tools such as Gradle plugins and mod development kits, NeoForge allows programmers to efficiently build, compile, and distribute mods for multiple versions of Minecraft. -

libGDX
Desktop/Android/HTML5/iOS Java game development framework
libGDX is a cross-platform Java game development framework based on OpenGL (ES) that works on Windows, Linux, macOS, Android, your browser and iOS. libGDX provides a well-tried and robust environment for rapid prototyping and fast iterations. libGDX does not force a specific design or coding style on you; it rather gives you the freedom to create a game the way you prefer. Publish your games on Windows, macOS, Linux (including the RPi!), Android, iOS, and HTML5, all with the same code base. libGDX comes with batteries included. Write 2D or 3D games and let libGDX worry about low-level details. Heavy emphasis is put on avoiding garbage collection for ART/JavaScript by careful API design and the use of custom collections. libGDX is a well proven and reliable framework with a sound base and documentation. Furthermore, there are plenty of games built on top of libGDX, many of which are open source. -

MAME4droid
MAME Android Emulator.
MAME4droid (0.139u1) is developed by David Valdeita (Seleuco), port of MAME 0.139u1 emulator by Nicola Salmoria and TEAM. MAME4droid (0.139u1) emulates arcade games supported by original MAME 0.139u1. This MAME4droid version is targeted to Dual-Core devices, because it is based on a high specs 2010 PC MAME build. Anyway don't expect arcade games of the 90 to work at full speed. With some games that are really bad optimized (like outrun or mk series) you will need at least a 1.5 ghz dual-core device (Cortex A15). This is related to MAME build used, since it is targeted to high specs PC's as i said before. This version emulates over 8000 different romsets. Please, try to understand that that with that amount of games, some will run better than others and some might not even run with MAME4droid. Please, don't email me asking for a specific game to run.

BedrockConnect
Join any Minecraft Bedrock Edition server IP on Xbox One
On Minecraft Bedrock Edition, players on Xbox One, Nintendo Switch, and PS4/PS5 are limited to playing on 'Featured Servers' approved by Mojang/Microsoft. These players are not able to join servers via an IP/address. This is an issue for me and others, as the server community on Java edition was one of the major parts that made Minecraft what it was, and what also made the servers that are now considered 'Mojang Server Partners' what they are today. I wanted to fix this, so I made a solution that anyone can set up easily. -

Iris
A modern shaders mod for Minecraft compatible with existing OptiFine
Iris was created to fill a void that I saw in the Minecraft customization and graphical enhancement community: the lack of an open-source shaders mod that would let me load my favorite shader packs on modern versions of the game, while retaining performance and compatibility with modpacks. OptiFine, the current dominant mod for loading shader packs, has restrictive licensing that firmly stands in the way of any sort of tinkering, and is fairly notorious for having compatibility issues with the mods that I like. It's also mutually incompatible with Sodium, the best rendering optimization mod in existence by a large margin. ShadersMod was never updated past 1.12, and it lacks support for many of the many modern popular shaderpacks. So I created Iris, to try and solve these issues, and also address many other longstanding issues with shader packs. I first and foremost develop Iris to meet my own needs of a performance-oriented shaders mod with good compatibility. -

GeyserMC
A bridge/proxy allowing you to connect to Minecraft
Geyser is an open-source proxy and protocol translation tool that enables cross-platform multiplayer between Minecraft: Java Edition servers and Minecraft: Bedrock Edition clients. The project works by translating network packets between the two different game protocols so that players using Bedrock Edition devices such as consoles, mobile phones, or Windows editions can connect to servers originally designed for Java Edition. By bridging the differences between the two platforms, Geyser allows server communities to unify players who would otherwise be separated by incompatible game editions. The software typically runs as a plugin, proxy, or standalone bridge and integrates with popular Java server platforms such as Spigot, Paper, or Velocity. -

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. -

Xonotic
Superproject containing build scripts and tools to download assets
Xonotic is a free, open-source arena-style first-person shooter video game that emphasizes fast-paced movement, skill-based combat, and a diverse arsenal, with gameplay reminiscent of classic shooters like Quake and Unreal Tournament. Born as a community fork of the Nexuiz project to preserve open development principles, Xonotic runs on an enhanced version of the DarkPlaces engine and supports Windows, macOS, and Linux platforms with no installation required beyond extracting the game files. Players can enjoy a wide variety of multiplayer game modes—from traditional deathmatch and team captures to experimental variations like Nexball and Freeze Tag—each designed to exploit high mobility and deep map knowledge. The game includes dozens of official and community-created maps, robust server browsing, customizable HUD and controls, and even an integrated statistics system called XonStat for tracking performance. -

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. -

SpongeForge
A Forge mod that implements SpongeAPI
A Forge implementation of the Sponge API. SpongeForge uses Gradle as its build system. The repo includes the Gradle wrapper that will automatically download the correct Gradle version. Local installations of Gradle may work but are untested. To execute the Gradle wrapper, run the ./gradlew script on Unix systems or only gradlew on Windows systems. In order to build SpongeForge you simply need to run the gradlew command. On Windows systems you should run gradlew instead of ./gradlew to invoke the Gradle wrapper. SpongeForge is the implementation of the Sponge API on the Minecraft Forge platform. Recommended for running plugins together with Forge mods. The purpose of the Sponge project is to create a plugin development framework for Minecraft: Java Edition. Sponge is being created by a global community, and its open-source nature means anyone can participate. -
