Kepler

A small TCP server written in C11 powered by libuv, an asynchronous networking library. It powers the Habbo Hotel version 18 client from 2007 era. The aim is to fully replicate this version by writing the back-end server in the C11 language.

This was the original Kepler emulator before it was recoded in Java. Both the C and Java versions share the same MySQL database schema.

Quick Install

Pre-built binaries are available from the latest release. The zip includes the binary and data files.
