Allay

The next-generation Minecraft: Bedrock Edition server software

Introduction

Allay is a third-party server software for Minecraft: Bedrock Edition written in Java with the goal of maintaining high scalability while maintaining high performance through a well-designed architecture.

Important

Please note that this project is still at a very early stage and has not yet been released officially, and a large number of interfaces may be added or removed without notice. Please do not use Allay in a production environment.

You can check our roadmap for development progress.

Features

Allay has many features that make it stand out from other server software, and here are some of them:

• Cross-platform: Allay is based on JVM, so it can run on most platforms that can run JVM.
• High Performance:
  • We fully understand the problems of Nukkit server under high load, Allay is a hundred times more performant than Nukkit in some aspects (eg: entity physics).
  • Thanks to the redesigned threading model, Allay takes full advantage of multicore CPUs, which means you don't need to intentionally use server that has high CPU frequency.
  • Allay is based on JDK 21, which theoretically gives it better performance.
• Easy to Get Started:
  • You can write plugins for Allay in Java, Kotlin, Scala (JVM based language) and script languages such as JavaScript, Python, etc.
  • We introduced GraalVM, which means you can write plugins in many languages and get the same performance as Java and the ability to interoperate seamlessly.
• Highly Customizable: Allay offers a large number of interfaces that can be used directly, and you can't do such thing in BDS.
• Security:
  • Allay has more checks on client packets than BDS, and theoretically does not have many of the pernicious vulnerabilities that BDS has.
  • Allay has network encryption enabled by default. In addition, Allay has a built-in resource packet encryption function that automatically encrypts resource packets sent to the client, preventing your data from leaking to a certain extent.
• Lots of New Features: Unlike the Nukkit server, Allay uses a lot of new protocol features that have been introduced by BDS, such as server-side authoritative inventory, new chunk format, sub-chunk packet sending, etc.
• High Code Quality: We pay a lot of attention to code quality and keep the project stable with the help of extensive unit testing and refactoring.

Getting Started

For Normal Users
