In seconds – right from your browser – you easily host or attend web meetings complete with audio and video conferencing, screen and application sharing. After experiencing the freedom and ease of Dimdim Web Meetings, you’ll wonder why you ever used expensive and difficult alternatives. Dimdim is a free web conferencing service where you can share your desktop, show slides, collaborate, chat, talk and broadcast via webcam with absolutely no download required for attendees. The Dimdim Web Meeting service is available in open source and commercial enterprise editions capable of supporting thousands of attendees. And unlike all other web meeting solutions, Dimdim is available in both onsite (you install it on your servers) and hosted (we install it on ours) configurations. Like you, they tried all those other web conferencing solutions and found them exceedingly expensive, difficult to implement and impossible to customize. So they created Dimdim as the easy, open and free web meeting alternative. Dimdim just works – no software to download or maintain, and it takes only a few clicks to join or host your very own meetings.
