Impostor private server for Among Us, hosting your own lobbies over the standard game protocol with matchmaking, anticheat checks and the server address resolved automatically on first boot.
Impostor is the standard open source private server for Among Us. Instead of playing over the official servers, you and your friends point your own game clients at a server you control: your own lobbies, your own rules, lower latency in the region you choose, and game traffic that never leaves infrastructure you own. Players keep using their normal, legitimately purchased copies of the game and simply import a small region file that points at your server, so nothing else needs installing on their side. The server reimplements the game's own connection flow faithfully, an HTTP matchmaking exchange that issues each player a token followed by the UDP game transport, honours anticheat style checks, and can be extended through a first class plugin API.
cloudimg ships a server that actually works the moment it boots. The single step that silently breaks most self hosted Among Us servers, telling the matchmaker the machine's real public address so lobby joins resolve correctly, happens automatically on first boot, and a connection note with the exact address and port to hand your players is written for the administrator. The service runs contained under a dedicated no shell account with a strict systemd sandbox, anticheat checks are enabled in the shipped configuration, and the .NET runtime underneath is installed from the Ubuntu archive so security updates apply automatically. A shipped self test proves the full client flow end to end, including a live handshake in the game's own wire protocol, and the paired deployment guide covers ports, region files, plugins and upgrades, backed by 24/7 cloudimg support.
