I’m sorry to be the bearer of bad news, but Hollywood has lied to you. We’re not getting hologram meetings anytime soon.

Until then, perhaps you should look to video conferencing (or web conferencing) software to help you meet up with all those distant relations and workplace proximity associates. After all, 63% of businesses are currently using group video conferencing software and 30% are currently implementing or deploying it, according to a Gartner survey.

Video conferencing software lets you host remote meetings, which cuts down on overhead, makes it easier to hire speakers since you no longer need to worry about travel, and helps you reach a much wider audience because you’re not bound by a single location.

You can use video conferencing software for events, internal meetings, webinars, and lectures, so it’s incredibly valuable. And it’s even more valuable if it’s free.

We’ve compiled a list of five of the top free video conferencing software for you. Several products on this list are open source, which means they’re infinitely customizable. However, you should approach those only if you a) have at least a rudimentary knowledge of programming and b) are comfortable not having much in the way of live customer support.

  • It has exceptional video and audio quality, according to reviewers.

Comment by Nicholas A Morpus on

Each of these tools are open source. Open-source software can be free or paid, depending on the developer’s preference. “Open-source” simply means the source code is open to the users changes and improvements.

Hey, above tools are not open source. They are paid tools similar to webex, R-HUB HD video conferencing servers etc.
