• Simple C++ API
• Serves static content from disk
• API for building WebSocket servers
• Simple command line binary for quick serving of static files only
• Supports newer Hybi-10 and Hybi-16 WebSockets as well as the older Hixie style.
• Supports Linux and Windows

• It's not nearly as configurable as Apache, Lighttpd, Nginx, Jetty, etc.
• It provides only limited support for custom content generation (e.g. Servlets).
• It has been designed for WebSocket based control.
• It probably won't work on other systems (patches to support other systems would be welcome, but not a priority for us)
