Easy to use yet decently feature laden, XChat Azure provides a well rounded way of connecting via the IRC networks on OS X devices. It’s a pretty good IRC client application, and certainly one you should check out if you use a Mac. And best of all, it’s free. How cool is that?
Having a fairly nice feature list, XChat Azure allows you to easily connect to multiple IRC servers and channels, making both general and private conversations effortless. There’s full support for file transfers as well. Add to it regular goodies like robust SSL support and an array of useful keyboard shortcuts, and XChat Azure makes a really good case of being a nice IRC client application for Mac OS X running computers. Oh, and it’s also an open source application, with the full source code hosted on GitHub. Pretty cool, right?
