Titanium is 1.8.8 Paper fork which aims to improve performance, fix exploits and bugs, improve API, and provide better configuration for server administrators.

Titanium officially supports JDK 8, 11 & 17 - but we recommend to use Java 17.

You can download the latest version of Titanium from Releases.

But also you can build it yourself. See How To Build.

If you want to build Titanium you will need these things to be installed and available from your shell:

• JDK 17
• Git

To patching, compiling and building Titanium you will use titanium script.

To just build Titanium clone this repository and run ./titanium build paperclip in the root directory. Then you will find your server jar in Titanium-Server/build/libs, it should be named titanium.jar.
