A plugin and mod loader for the Space Engineers (SE1) Dedicated Server. Hard fork of Pulsar, adapted to run the headless dedicated server — no WinForms, no Telerik UI, no Windows-service host.
Magnetar ships two launchers that drop in for SpaceEngineersDedicated.exe:
| Launcher | Runtime | Platforms |
|---|---|---|
MagnetarLegacy |
.NET Framework 4.8 | Windows only |
MagnetarInterim |
.NET 10 (via dotnet-compat) | Windows + Linux |
On Windows both launchers are built; on Linux only MagnetarInterim
(.NET 10).
Compatibility plugins are loaded implicitly:
- dotnet-compat for .NET 10 compatibility
- linux-compat for Linux compatibility
You can register new plugins by making PRs to the MagnetarHub.
Quasar is a separate control plane with a Web UI that can manage and control multiple Magnetar instances from one place. Each Magnetar reports structured status and logs; Quasar orchestrates them.
