Bastly is an open source solution, so you can deploy on your own instances our software and use it for free (AGPL2)

The hacker plan is enough to test it out without the hassle of deploying the instances, then is a paid service based on how many concurrent users/messages you send. Don't hesitate to ask us for startup plans, discounts, etc.

Register to get an APIKEY and you can test it out pushing objects to our ORION instance at the moment http://orion.bastly.com:1026/ and following the doc https://github.com/Bastly/bastly-sdk-android how to get updates based on a channel. I'll make a step-to-step guide for Orion in the next week.

We are working on allowing to config your own Orion instance from the user panel, it will be ready around next week

Ping me on alex@bastly.com for any help that you may need.

The specific code that handles the Orion subscription pushes to sockets is on Bastly/connector-rest:

We use ZeroMQ to send messages across platforms and a translator from ZeroMQ to SocketIO for webs, chaski workers are in charge of that:

And all the request are handled through Atahualpa that decides where to forward the messages using a data bus and an operations bus:

Take a look at the bastly service. It does exactly what you want and it already works with Orion.
