MCreator
Make Minecraft Java Edition mods, Minecraft Bedrock Edition Add-Ons
MCreator is an open-source integrated development environment designed to simplify the process of creating Minecraft mods, add-ons, resource packs, and data packs. The software provides a visual programming environment where users can design mod features using graphical tools instead of writing code manually. Through wizards, block-based programming interfaces, and an integrated editor, MCreator generates the underlying Java or JSON code required for the mod automatically. This approach allows beginners and students to experiment with mod development without needing extensive programming experience. At the same time, advanced users can extend the tool through plugins or directly modify the generated code for more complex projects. MCreator is widely used in educational settings, modding communities, and programming workshops as a gateway into game development. -

BungeeCord
BungeeCord, the 6th in a generation of server portal suites
BungeeCord is a Minecraft server proxy designed to connect multiple Minecraft servers into one larger network. It lets players move between separate servers while experiencing them as part of the same connected environment. The project is maintained by SpigotMC and has long been used by server owners who operate lobby, minigame, survival, creative, and specialized game-mode networks. BungeeCord works as a layer between players and backend servers, forwarding connections and managing server-to-server transitions. It also provides an API that developers can use to create plugins and extend proxy behavior. Its main value is helping Minecraft communities scale beyond a single server while keeping navigation smoother for players. -

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. -

SteelMC
A Minecraft server in Rust focused on a strong foundation
SteelMC is an independent Minecraft Java Edition server implementation written in Rust. It aims to reproduce vanilla behavior while using modern multicore processors more efficiently. Gameplay updates remain synchronous, while chunk generation, lighting, packet processing, and chunk transmission can run outside the main server tick. Players can join persistent multiplayer worlds, move, interact with blocks, manage inventories, use commands, chat, and return to previously saved areas. Its networking layer supports Java Edition authentication, encryption, compression, and protocol communication. World generation is currently its most complete system and is tested against reproducible vanilla chunks for block-level parity. SteelMC remains in pre-alpha, with incomplete survival mechanics, limited entity behavior, no plugin system, and no compatibility with Bukkit, Paper, Fabric, Forge, or NeoForge extensions. -

Minecraft server optimization guide
Minecraft server optimization guide
Minecraft Optimization Guide is an open-source documentation project that provides practical guidance for improving the performance of Minecraft servers. Rather than offering a single universal configuration, the guide explains how different server settings, software choices, and infrastructure decisions affect server performance and stability. It covers a wide range of topics including server software selection, configuration tuning, JVM parameters, hardware considerations, and common mistakes that can cause lag or instability. The goal of the project is to help administrators understand how the Minecraft server engine works so they can make informed decisions about optimization rather than blindly applying configuration changes. The documentation emphasizes experimentation and explains that every server has different requirements depending on player count, hardware, and gameplay style. -

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. -

Players can protect their own builds with minimal administrator involvement, which makes it useful for public survival servers with many users. The project targets current Spigot, Paper, and Purpur servers, while older versions remain available separately for legacy Minecraft environments. It also has an addon ecosystem for extending protection behavior beyond the core plugin. GriefPrevention is best suited for server owners who want practical build protection, fewer moderation emergencies, and a player-friendly claiming system.
