Fosscord is a free open-source discord compatible chat, voice and video platform
It is not impossible to duplicate Discord (e.g. www.kaiheila.cn ), but what makes a SNS unique is really the user base.<p>WeChat sucks, but it's still used by billions. People are not using WeChat because WeChat is great or Tencent is great. People are using WeChat because their family, friends, employers, favorite medias and hospital reservation services are there.
