We are starting to see increased adoption of WebSockets around the web. The WebSockets standard is making it much easier for developers to build real-time event driven applications. This is especially useful in the Bitcoin world, as the Bitcoin network and payments ecosystem is inherently event-driven.

Blockchain.info, Coinbase’s Exchange, and Ripple Labs all have WebSockets APIs, providing developers with a rich source of real-time data to use in their applications.

To make it easier for developers to quickly view these data feeds, I build a tool called WebSocketListener.com. The source code can be found here.
