Here, you’ll see a list of a pre-compiled list that will be updated overtime whenever i find any new links that is related to, services that enable you to chat over a network without have to install any software on the computer that you are using, applicable to most of the office users. Do let me know if you found any more.
This is browser/web based ICQ chat client that provided by ICQ themself.
Being one of the popular one around the internet, eMessenger supports up to 3 type of protocol, MSN, Yahoo and AOL. But of course, with smileys, and icons as their feature, you’ll have to deal with bunch of ads floating around the browser.
Java Browser based client for MSN, which is not really on the funky side for the interface, but much or less enough for you if you just want to chat, much on the low-profile side, if you decide to hide and not let other people notice you chatting 😉
A very super hyper powerful chat client, powered by AJAX. These dudes behind this project are really up to the ‘next’ thing. Going to soon support on various language, which is now, already sufficient to act almost-like the actual chat client, which supports, AOL, Yahoo, MSN and Gtalk/Jabber. Real cool, a MUST TRY!
Web Msn Messenger
Browser based MSN Messenger provided by MSN themself, the most-look-alike client that emulates most from what the original provides, but of course, if your place blocks this domain, i’d suggest you give a try at the other web based clients.
Another feature packed browser based Google Talk client, built on flash, you’ll be amazed on the performance and feedback given to you. Not only acting as a chat client, you’ll have access at one go, to your inbox, YouTube videos, Flickr’s Pictures. Very useful stuff.
Update 5/25 : If you are looking into more alternatives, the link below will take you further towards the rest of the online chat application.
