JWChat is a full featured, web-based XMPP 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. For a list of supported browsers see
the features page

All of your settings, bookmarks and your contact list are stored on
the server side. This means that you have access to your personalized
client from almost any computer as long as it’s got access to the

JWChat and its underlying software are all Open Source. This
gives you the flexibility you need in your everyday business.

JWChat brings you the perfect solution for your corporate
communication. Being a web application it gives you all advantages of
centralized software distribution. Don’t hassle with software installs
and updates on the client side!
