About
Project Origin
The original Impostor project by AeonLucid pioneered the community-driven open-source reimplementation of the Among Us server. However, after being taken over by miniduikboot and NikoCat233, Impostor increasingly shifted towards a closed-source mentality — and its feature set remained too basic for real-world server hosting.
NikoCat233 later developed Nmpostor, a server built on top of Impostor, but priced it at 180 CNY per person. For an open-source community, this was prohibitively expensive. The community was left without a feature-rich, truly open Among Us private server.
That's when HayashiUme and Fangkuai set out to build Next-Impostor — a more capable, open alternative. The project grew quickly, but accumulated so many bugs and architectural issues that development had to be halted.
Fangkuai then started Fast-Impostor as a clean-slate rewrite of an enhanced Impostor server. With different architectural beliefs, HayashiUme set out to build Empostor (github.com/Empostor/Empostor) — and Fangkuai happily agreed to contribute alongside his own work on Fast-Impostor.
Together, our goal is to give the community what it always deserved: a stable, feature-rich, plugin-extensible, and truly open-source Among Us private server.
