CGI:IRC: CGI:IRC is a Perl/CGI program that allows you to use IRC from a Web browser without having to have access to an IRC port. It does not use Java, but it does need a browser capable of rendering frames. It can be used on a Web page to allow users to chat, or it can be used to access chat from behind a firewall. CGI:IRC has an interface similar to many GUI IRC clients, with a tab for each channel, userlist and options tab (when used in modern, version 5+ browsers). Older browsers degrade to a single windowed interface with a slower updating userlist.

CWirc: CWirc is a plugin for the X-Chat IRC client to transmit raw Morse code over the internet using IRC servers as reflectors. The transmitted Morse code can be received in near real-time by other X-Chat clients with the CWirc plugin. CWirc tries to emulate a standard amateur radio rig: it sends and receives Morse over virtual channels, and it can listen to multiple senders transmitting on the same channel. Morse code is keyed locally using a straight or iambic key connected to a serial port, or using the mouse buttons, and sound plays through the sound card, or through an external sounder.

Conversations allows you to easily send images, show if your contact has received and read your message, permit dynamic history and handles multiple devices (especially sync with desktop clients), allow you to create group chats and support one-to-one Audio/Video calls ! And thanks to the XMPP Protocol (that is a push protocol) you battery life is safe. Conversations also does not require a Google Account or specifically Google Cloud Messaging (GCM). Using the XMPP federated protocol, you can freely choose a trustworthy server (your own if you want) for yourself while still chatting with contacts that are using other servers. The communication between Conversations and the XMPP server as well as the communication between the individual servers is TLS encrypted. This way, not only your messages are safe but more importantly it is impossible for an outside attacker to intercept your meta data (with whom you are chatting) without attacking your server first. On top of that, Conversations gives you the choice to enable one of two end-to-end encryption mechanisms. The first one is OMEMO, a state of the art multi-end-to-multi-end encryption method which is very easy to setup and gives you forward secrecy and plausible deniability. For backwards compatibility reasons Conversations also supports OpenPGP.
