    Minestom

    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.

    Project Malmo

    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.
