Software:Comparison of Internet Relay Chat clients

From HandWiki
Short description: none
This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by expanding it with reliably sourced entries.
For a comparison of instant messaging clients (including multi-protocol clients that support IRC), see Comparison of cross-platform instant messaging clients. For a comparison of mobile Internet Relay Chat clients, see Comparison of mobile Internet Relay Chat clients.

The following tables compare general and technical information between a number of notable IRC client programs which have been discussed in independent, reliable prior published sources.

Direct Client-to-Client (DCC) support

The Direct Client-to-Client Protocol (DCC) has been the primary method of establishing connections directly between IRC clients for a long time now. Once established, DCC connections bypass the IRC network and servers, allowing for all sorts of data to be transferred between clients including files and direct chat sessions.
