Latest commit e26bafa Oct 20, 2018


Melia is an open-source MMORPG server software for the international client of Tree of Savior. It's solely being developed for educational purposes, learning about programming, MMORPGs, maintaining huge projects, working with other people, and improving knowledge. It's not about playing a game or competing with any services provided by IMCGAMES or its partners, and we don't endorse such actions.

Melia is completely free and licensed under the GNU GPL. As such, every user is free to use Melia and choose how to use it, in the context of its license.


Melia is only compatible to the latest iTOS client, compatibility to any other clients or versions is not guaranteed, and in fact unlikely.

State of Development

Melia is not being actively developed at the current time, and hasn't been since the game's release. As a result the implemented features are few, and the only updates that are regularly made are to keep up the compatibility to the latest client. However, you're very welcome to work on Melia, make pull requests, and ask questions on the chat at any time.

The features that are currently working are the following:

  • Login Server
    • Character management
  • Channel Server
    • Chat
    • Inventory management
    • Equipment
    • Stats
    • Skill list
    • Very basic test melee combat
    • NPC dialog
    • NPC shops


To run Melia, you need

  • .NET 4.5 (Mono 4 or above)
  • MySQL 5 compatible database

To compile Melia, you need


  • Compile Melia
  • Run sql/main.sql to setup the database
  • Copy system/conf/database.conf to user/conf/, adjust the necessary values and remove the rest.

Afterwards, you should be able to start Melia via the provided scripts or directly from the bin directories. If not, or if you need a more detailed guide, head over to our forum, the chat, or the wiki.
