QWebSockets is a pure Qt implementation of the HTML5 WebSocket specification. It supports both text and binary messages, frame- and message-based processing and can be used to implement clients and servers. The repository can be found on GitHub. QWebSockets has an LGPL license, and hence can be used freely in both open source and commercial applications. Although the code is stable and already used in a number of projects, the version is still 0.9. We hope to release version 1.0 very soon, as soon as all outstanding issues have been resolved.
