Pusher is a simple hosted API for quickly, easily and securely adding realtime bi-directional functionality via WebSockets to web and mobile apps, or any other Internet connected device.
Our event based abstraction makes it simple to bind UI interactions to events that are triggered from any client or server.
As well as a WebSockets API, we have a REST API for publishing your messages. This is ideally suited to web server technologies and we have a set of REST API libraries in many common languages to help you to do this.
We have a simple Publish/Subscribe model based on channels that allows you to filter and control how people receive your messages.
We supply functionality such as authentication mechanisms for private channels, and presence functionality for keeping track of who's online.
The following is a list of libraries from ProgrammableWeb's Library Directory that matched your search term. Although there many different interpretations of the word "library" among software developers, ProgrammableWeb adheres to a specific definition so as to clearly distinguish libraries from SDKs and frameworks in a way that will facilitate clean search results. In ProgrammableWeb's parlance, the term "library" is strictly used to describe a platform-specific software tool that, when installed, results in the provisioning a specific API. Conversely, SDKs are exclusively for consuming APIs and Frameworks are agnostic to specific APIs. If you think a library, SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
