Malliks Review: diMdiM, poor man's WebEx

DIMDIM is a free web conferencing service where you can share your desktop, show slides, collaborate, chat, talk and conduct a session via webcam. DimDim is open source web meeting company. Dimdim is backed by the original investors in Skype, Hotmail, and MySQL. Dimdim is based in Boston,Massachusetts with offices in New Hampshire, Canada and India. Most of the engineering work is done in Hyderabad India. DimDim offers the service for free for upto 20 users & 1 webcam in meeting. For more features you can use the Pro version which is still much cheaper than Web ex.
Malliks Testing:
DimDim has been tested thoroughly by me and application is cool but you need good internet bandwidth for things to work as expected. Below are the some of the bugs found as part of Malliks Testing.
  • HTML/JS injection(XSS) is possible at many places on DimDim because of improper handling of html & js code.
  • Some of the cookies are storing the passwords in plain text format which is not appreciated from security perspective.
  • Member knowing pptId and meetingId can open the presentation even without being member of meeting which is not appreciated.
Malliks Rating: 4/5

Location: Hyderabad, India and Massachusetts, US
Funding: $8.4M (Last funding of $6M on July 9th 2008 From Index Ventures, Nexus India Capital, and Draper Richards.)


  1. Mallik-

    Thanks for the Dimdim review. I've let our engineering team know about the issues you've raised. We have done significant work to reduce the amount of bandwidth required for some of the meeting components -- expect to see those changes live in under 2 weeks.

    I've been testing DimDim on-and-off for the past year for a SMB. Everytime we think it's going to work flawlessly, there's always an issue. Today it was white noise. It such a great concept to Webex, but it's got to work robustly for it to really gather strength.

  3. I want to suggest you try - Its an alternative tool to dimdim, for collaborating online and document sharing without needing to install anything. Try it.
