BlueMap
A Minecraft mapping tool that creates 3D models of your Minecraft
BlueMap is a program that reads your Minecraft world files and generates not only a map, but also 3D models of the whole surface. With the web app you then can look at those in your browser and basically view the world as if you were ingame! Or just look at it from far away to get an overview. BlueMap comes as a Spigot/Paper or Sponge Plugin, as a Fabric or Forge-Mod and you can also use BlueMap without any Server from the Command-Line as a standalone tool. If installed as a Plugin/Mod, BlueMap renders asynchronously to your MinecraftServer-Thread. This means at no time it will block your server thread directly. So as long as your CPU is not fully utilized, your server should not be slowed down while BlueMap is rendering. -

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. -

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. -

Master of Magic - IME
Multiplayer Java rewrite of Simtex's classic game Master of Magic
This is a multiplayer client/server java rewrite of Microprose/Simtex's classic DOS turn based strategy game Master of Magic. Latest versions now require Java 25, however since a lot of folks have been having trouble setting this up, I am now providing 2 versions, one with a JRE included in the download, and one without. Beyond this, it should just be as simple as unzipping the file and running server.bat to get the server running locally, and client.bat to start up the client. See the readme for more details. The project is effectively finished at this point and I did not really plan any further major releases. However Simbey has been commissioning an artist to upscale all the graphics from the original game so these have been incorporated into 1.7.0. By default it uses the original graphics, you need to enable the upscaled graphics in the options screen. I am at the MoM discord server at https://discord.gg/wFNQf36 Or can message me or raise ticket on SourceForge -
