Open Source Web Conferencing Options

One open source tool that I use regularly is DimDim. It was the application we used at work and through the SLA for hosting web based meetings. Recently it was announced that DimDim is being sold and when you look at their SourceForge page you see that they haven’t released a new open source version since 2009. So the question becomes, “now what?”

I did some searching today to see what options were out there. There is still WebHuddle which I knew about already but didn’t like as much as DimDim and then there’s a tool I didn’t know about until today – BigBlueButton.

From their site:

BigBlueButton is an open source web conferencing system built on over fourteen open source components to create an integrated solution that runs on mac, unix, or PC computers. In the true sense of open source, we invite you to try out and participate in our project.

Sounds like the perfect alternative!! It doesn’t look like there is a hosted option, so you’d have to install it on your own web servers, but once you do that you have an open source web conferencing application which will allow you to share your screen, slides, video (webcam), text chat and voice over ip. I’m going to look further into BigBlueButton, but I thought I’d mention it to you all in case anyone else was out there searching like I was.


  1. Have you considered midmid? I think it’s a child of dimdim, so the server is free and open source software, but it needs adobe flash on the client, which isn’t FOSS

  2. I hadn’t heard of it, but a look at the Google Code page shows that there aren’t any downloads yet. I’ll add it to my bookmarks to watch.

  3. I haven’t tried it, and I’m not sure if the license used (Eclipse public license) would be a problem for you, but while looking for an equivalent to dimdim, I stumbled upon openmeetings.

    In my case, turns out I had access to a fee-based service all along, so I’m going the easy way.

  4. Thanks Nicole for covering our open source project! We’ve been working on BigBlueButton for over four years our focus is on providing remote students a high-quality learning experience.
