JWChat is a full featured, web-based Jabber™ client. Written using AJAX technology it relies on JavaScript and HTML at the client-side only. It supports basic
jabber instant messaging, roster management and groupchats based on the
MUC protocol.

JWChat is an advanced instant messenger (IM) just like AIM, MSN
Messenger, Yahoo! Messenger or ICQ. This means you can manage your
contacts, communicate with other users in 1:1 chat sessions or join a groupchat room for
collaborative communication. Unlike other IMs you can use this with your
web browser without having to install any additional software at
all.
