Myst Online: Uru Live: 5 Open Source Clones Compared
Of the three server implementations here, DIRTSAND is the most established (active development, AGPLv3) but is tested only on Linux with no Windows support planned, though it can run under Docker elsewhere for local testing. MOULArs, written in Rust, is designed to be DirtSand-compatible while adding memory safety, simpler setup, and better native cross-platform support including Windows, though its own database-setup documentation is still marked as to-be-determined. NAGUS, an experimental Python server, is described by its own author as 'not very good' and explicitly points users toward MOSS or DIRTSAND for a working setup instead. Plasma, separately, is the game client rather than a server, and needs to be paired with one of these server projects plus a separate game-asset repository to actually run.
