Wt (pronounced as witty) is a C++ library for developing interactive web applications.

Wt (pronounced as witty) is a C++ library for developing interactive web applications. The framework is structured around widgets using signals and slots to drive interaction in the application. The framework comes with automatic fall-back for browsers which don't support the level of Javascript used in creating the application interface, such as web crawlers. WebSocket connections are supported out of the box. The framework provides extended built-in security, including XSS, CSRF and application logic attack prevention.

Bug reports, feature requests and official support requests should be posted here.
