NetIRC2 is an easy-to-use .NET IRC client library. It supports all major features relevant to making a chat client or bot. It has full support for synchronization contexts. You can use it from a Windows Forms or WPF GUI thread and chat events will be automatically dispatched, allowing you to completely ignore multithreading. It uses byte arrays internally, so mixed encodings can be handled. The IrcClient class can even be used as a component in the Forms Designer. Because it speeds up connect times with some IRC servers, an Ident server is included as well.
123 Live Help is a Web-based support software for businesses. It shows visitors to your Web site that a live agent is just a click away and enables operators to chat in real time with them. There are text and video chat options. It is secure, fast, flexible, customizable, and cost-effective. There is a full-featured administrative panel for operators and administrators, allowing them to automatically detect customers' details, track their footprints, transfer chats, follow the visitor's Web browsing, check spelling, get canned messages, and more. Administrators also can monitor all chat sessions and get statistics on the traffic sources of visitors and performance of operators.
Smuxi is an irssi-inspired, flexible, user-friendly, and cross-platform IRC client for sophisticated users. Smuxi is based on the client-server model: The core application (engine) can be placed onto a server which is connected to the Internet around-the-clock; one or more frontends then connect to the core. This allows the connection to IRC to be kept up even when all frontends have been closed. The combination of screen and irssi served as the example for this architecture. Smuxi also supports the regular single application mode. This behaves like a typical IRC client; it doesn't need separate core management and utilizes a local engine that is used by the local frontend client.
