The PubNub Network makes Real-time Communications Simple with an easy API. Two Functions: Send/Receive (Publish/Subscribe). We provide a web-scale API for businesses to build scalable Data Push communication apps on Mobile, Tablet and Web. Bidirectional JSON.

You are here because you need to send and receive data between devices in real-time without bothering with the complexities of managing a messaging service. You will typically start by selecting your target platforms first and then mixing/matching the APIs for your supported platform. For example you are building an iOS App for the iPhone using PubNub's Objective-C SDK plus PubNub's Ruby SDK running a Ruby on Rails application server. This would allow you to send messages from your Ruby application server directly to the iPhone in Real-time.
Play with the PubNub API on Mashape: https://www.mashape.com/pubnub/pubnub-network#documentation
Note: Some APIs require you to have your own PubNub Account. However you may use the
demoPub/Sub keys for testing purposes.
There are lots of options so start here if you want to find your target platform. The following list of languages and platforms are the PubNub Network A+ Grade SDKs. There are many languages and SDKs that exist which connect to PubNub Network today. The following list is our officially supported SDKs:
