OpenMU is an open-source, from-scratch C#/.NET server implementation (emulator) for the MMORPG MU Online, focusing on Season 6 Episode 3 with an extended protocol for an open-source client. It includes an admin panel, customizable attribute system, Docker deployment, and reusable network/packet NuGet libraries.

Use cases

  • host a private MU Online game server
  • run a customizable MMORPG server emulator
  • self-host a game server with Docker
  • understand the MU Online network protocol
  • build tooling on top of MU Online packet libraries
  • experiment with game server architecture patterns

When to choose

  • you want a legal, clean-room MU Online server instead of decompiled private server software
  • you need an extendable, customizable game server with an admin panel and configurable gameplay
  • you want to run the server easily via Docker on Windows or Linux

When to avoid

  • you need 100% identical behavior to the original Webzen server
  • you want a turnkey, production-ready release - the project is still under development without a stable release
  • you are not a developer and expect polished out-of-the-box hosting
