Reading that PR release and their landing page, there are so many unanswered questions.

How is this different from PubNub or Pusher, which also provide push as a service? What is the pricing for the service? Are there first-party libraries for popular languages?

Hey there. The main difference is that Fanout is invisible to clients. You explicitly choose the data transports and formats. This makes it well-suited for fronting public APIs, since you're in control of the interface. Our codebase is also open source.

This article goes into good detail about the reference implementation for our HTTP transport: http://blog.fanout.io/2013/04/09/an-http-reverse-proxy-for-r...

Although it could be made more apparent, we have Python and Node libraries in our GitHub: https://github.com/fanout/

Also RealCrowd developed a .NET library: https://github.com/realcrowd/grip.net

kudos for being opensource.that's in my opinion the right model.try localy then scale in the cloud!

Cool, but what does this have to do with OneBusAway? (the service depicted in the monitor in the photo accompanying the article).

(Fanout guy here)

We're not sure! We're not working with OneBusAway, but I think the author of the article was trying to convey a sense of realtime with that image.

Sorry for the confusion!

No sweat. I'm actually one of the developers on the iOS version of the app and was just sort of surprised to see it at the top of the article!

We're here if anyone has questions. :)

Do you have any information about pricing?

Currently free for testing or low volume production use. We'll be rolling out our pricing page in the near future!

We really want this to be the easiest and most cost effective way to scale realtime so if you have a specific use case in mind we'd love to hear more!
