XASECO is server-side controller software whose features are supplied through plugins. It is an administrator tool, not a replacement for the Trackmania game client. Compatibility depends on the server build, plugin versions and operating environment.
Safe administration
Admins should document versions, keep backups and test changes privately before changing a public server. Players should never provide passwords or game keys to a plugin author or server operator.
Use the live viewer for confirmed server information and ask compatibility questions in the forum.
