Installation video for BigBlueButton 1.1-beta

To help anyone installing BigBlueButton for the first time, we’ve created an installation video that walks you through the install steps at BigBlueButton 1.1-beta installation guide.

The video covers

  • installing BigBlueButton 1.1-beta (or later) on an new server
  • assigning a hostname, and
  • configuring it with SSL certificate from Let’s Encrypt.

Closed Captioning and Breakout Rooms (BigBlueButton 1.1-beta)

Hi Everyone,

We are very pleased to announce the availability of BigBlueButton 1.1-beta that adds the following enhancements:

  • Breakout Rooms
  • Live Closed Captioning
  • Faster Desktop Sharing

BigBlueButton is an open source web conferencing system for online learning. The goal of the project is to provide remote students a high-quality online learning experience.

The addition of breakout rooms will enable instructors to increase collaboration among students. The addition of live closed captioning will add to the existing support of JAWS screen readers to support students with disabilities.

We’ve put together three videos to demonstrate the new features:

Breakout Rooms

Live Closed Captioning

Faster Desktop Sharing


This release is built upon the excellent Ubuntu 16.04 distribution, which enabled us to simplify the install instructions (no more need to install ruby or libreoffice) and to convert the init scripts to systemd (thereby making them more stable).

The new desktop sharing is faster, captures the cursor, runs again on Chrome, and no longer needs port 9123 open on the BigBlueButon server.

To setup and develop upon BigBlueButton 1.1-beta, see install guide, overview of what’s new, and setting up a development environment

Towards a Release Candidate

Overall, you’ll find this release is simpler to install and provides some core features that you would expect in a web conferencing system built for online learning. We’re working on finishing up the documentation and localization for this beta release and moving towards a release candidate.

We invite everyone in our community to try out this beta release and post your feedback to our bigbluebutton-dev mailing list.


BigBlueButton Developer Summit IX

BigBlueButton 1.0 Released


The BigBlueButton project is pleased to announce the release of BigBlueButton 1.0, our 15th release in over seven years of development.

BigBlueButton is an open source web conferencing system for online learning. The goal of the project is to provide remote students a high-quality online learning experience.

This release gives instructors more abilities to engage remote students by adding:

  • Polling Module
  • Emoticons
  • Improved Video Dock

In addition to the above features, this release saw significant advancements in stability, usability, accessibility, leaning management systems (LMS) integration, localization, and design wins.

We released BigBlueButton 1.0-beta over six months ago (October 15, 2015). Since then, a number of commercial companies have been running it in production under continuous load for months (we know of one company that has hosted over 100,000 live sessions to-date).

This extensive beta testing period enabled us to stress the client and server under heavy load, find any areas that might impact the stability of a live class, fix them, and confirm they were fixed.

This all makes BigBlueButton 1.0 our most stable release to date. The focus on stability has paid off over the years.

“Our instructors love BigBlueButton. With our previous web-conferencing solution our users encountered many technical and usability problems that caused a lot of support effort on our part. With BigBlueButton, the support issues are almost non-existent. We are constantly impressed with the level of quality in this open source project.”

— Marc Matthes, Director of Computer Networking Programs and Program Developer, Distance Learning Department, Iowa Central Community College


We designed BigBlueButton to make it easy for an instructor to engage remote students online. For example, the new polling module automatically reads the text of the current slide and, if it detects a poll-type question, gives the instructor a single button to initiate a poll.

This detection enables an instructor to easily and rapidly ask multiple polls during a lecture without having to type in any of the questions during the class.

BigBlueButton uses web real-time communication (WebRTC) capabilities (in FireFox and Chrome) for very high-quality audio. This new version detects the loss of Internet connection (which can occur on a wireless network) and automatically attempts to reconnect the client and audio.


Accessibility is very important to us and to our target market. As with each release, we have an external firm audit BigBlueButton’s support for accessibility (specifically using screen readers such as JAWS) and give an independent assessment. You can view the accessibility statement for BigBlueButton 1.0, along with the link to our completed voluntary product accessibility template (VPAT), at

LMS Integration

BigBlueButton has deep implementations with many learning management systems. There are native plugins available for Moodle, Sakai, Canvas, Schoology, and Jenzabar. BigBlueButton is also certified as LTI 1.0 compliant, giving it a direct integration with every major LMS.


Thanks to our world-wide community, the BigBlueButton client has been localized into Arabic, Czech, Danish, Estonian, French, German, Greek, Hungarian, Italian, Japanese, Occitan, Polish, Portuguese, Russian, Spanish, Turkish, Ukrainian, Vietnamese, and other languages.

Anyone can contribute to the localization effort.

Design Wins

While the project’s focus is on online learning, BigBlueButton’s ability to provide for real-time sharing of audio, video, slides, chat, polls, and desktop make it applicable to many market segments.

Recently, the US Department of Defense built and deployed an internal collaboration system based on BigBlueButton and publicly stated they expect to save over $12m a year using it.

This was a huge design win for the project and BigBlueButton community.


If you are an educational institution delivering live courses online, or a commercial company looking to integrate live collaboration in your product, this release is a significant step towards our efforts to give you a solid web conferencing platform on which to integrate and build upon.
