Great to see a open source project from WeChat. WeChat is extremely viral in China. I am sure there is some amazing engineering work underneath.

  The language barrier has been their main issue, they'd definitely would love to collaborate more with teams outside of China I know. They have an astonishing amount of dev resources as well, they wrote an entire cloud platform (they're at maybe 10% of AWS) from scratch, in C.

      Their public cloud is http://qcloud.com/ http://qcloud.com/, I don't think everything they've written on the backend is public however.

        It has nothing to do with WeChat. qcloud is developed by TEG (Tech. Engineering Group), and the cloud service for WeChat is developed by WXG (Weixin Group).

      In C++ actually. Few years back Tencent had three internal teams making Wechat, the GuangZhou based Foxmail team won. Wechat IM protocol is basically a modified version of Microsoft Exchange.
