    Impostor

    Impostor

    An open source reimplementation of the Among Us Server

    Impostor is an open source reimplementation of the Among Us Server, written in C#. It is among the first Among Us private servers with support for Steam, Itch, Android and iOS. It is a full replacement of the game's official server, so you can expect all of the game's features to be included, and the same fun playing experience. The difference of course is that you get to play on a private and secure server. Impostor has plugin support as well as a server-sided anticheat feature. You also have the option of playing on a server hosted by someone else.
