PubNub has a generous free plan that you can use forever for non-productions applications. When you are ready to move your application to production and scale it to a larger audience, we provide two paid plans that are based on usage (transactions) with no limit on concurrent connections, no limit on channels and no limit on devices. 


For more details, please visit our Pricing Page, and contact PubNub Support if you would like to talk to an Customer Success representative about the details.
