The core web conference system

Mconf-Live is the core web conference system on Mconf. It is based on BigBlueButton, one of the best (if not the best) open source web conferencing softwares today. In Mconf we are not only using BigBlueButton, but also contributing to its development. Modules developed by Mconf include: the video dock, the layouts module, the global audio, the guest feature, and several others.



The web application that provides access to Mconf

Mconf-Web is an open source web portal, a web application implemented in Ruby on Rails, that acts as the interface between users and Mconf. On Mconf-Web every user has their own web conference room and users can interact in spaces, shared groups where people with the same interests can interact synchronously and asynchronously. You can register for free on to test the web portal and Mconf.



Use Mconf in mobile devices

Mconf’s mobile client started as an Android native application called Mconf-Mobile. It was discontinued in favor of an entirely new application developed with the framework Adobe Air that offers several advantages over the previous version, such as the support for both Android and iOS. This application is still in development but there is already a beta version available in the mobile stores!

Starting with Mconf

A quick overview on how to start using Mconf

  • Create an account

    It is extremely simple to start testing and using Mconf. Just create an account on our web portal and you will receive one permanent personal web conference room.

  • Share your meeting

    Create your own conferences and invite other people by sharing your room’s URL. Other people can simply access this URL in their browsers and join the meeting.

  • Communities

    Mconf allows you to create communities, shared spaces that have their own web conference rooms and where people can collaborate synchronously and asynchronously.

  • Join a meeting

    You can open your room at any moment from your home page by clicking in the button “Start a new meeting”. Your room will have a unique URL based on your username. For example:

  • Private meetings

    The users you invite to your web conference don’t necessarily need to be registered to access it. And if you don’t want anyone accessing it, you can protect your room with a password.

  • Mobile access

    If you want to join a web conference from a mobile device, you can install Mconf’s mobile client on your Android and iOS devices.
