Nginx is a general purpose webserver/proxy.

Fanout is meant for pushing data only. It uses a proxy-based mechanism to interface with the sender, but it's not a general purpose proxy like Nginx. You might even use Fanout and Nginx together, for example if you Nginx as a load balancer in front of our open source version (Pushpin).

Nginx does have a stream module, called Nchan. The main difference is Fanout is fully transparent and can speak any API you define, whereas Nchan somewhat speaks its own protocol and may not be able to power arbitrary predefined APIs. That said, Nchan is far more flexible than most push systems out there, and you can probably get it to do Fanout-like things.

Yep, I thought of the same - WebServer + an abstraction layer containing (NginX+Fanout) would be something I'll be trying. Look pretty cool, will check it out. So theres Fanout Cloud, but do you have an On-Prem version as well ? We have 1000s of customers, accessing millions of data records/sec via the APIs. This will definitely help us.
