Looking for open-source Zoom alternatives? We have compiled a list of the 10 best free Zoom alternatives in 2022

The Pandemic looming over the world for the past couple of years has brought about a lot of changes in our lives. 

This is especially true for how we now perceive the professional world. With everyone confined at home, our jobs are now more virtual than ever. 

Conference room meetings have now shifted to the virtual conference rooms provided by tools like Zoom. 

Open-source zoom alternatives

With over 300 million daily meeting participants worldwide, Zoom has become synonymous with video calling for businesses around the globe. 

However, Zoom is not the end-all-be-all of virtual meeting software. It comes with its fair share of limitations. The good news is that there are many new apps coming up in the market addressing said limitations.

As a result, many businesses are now shifting to other Zoom alternative platforms. 

In this article, we have listed some of the best open-source Zoom alternatives and why these can be the next best choice for most users today.

Why Switch to an Open-source Zoom Alternative?

While Zoom has been the go-to video conferencing tool for many, there are many reasons to pick an open-source Zoom alternative: 

  1. When you choose an open-source Zoom alternative, you have more flexibility and liberty with speech and expression. 
  2. You can study and modify the underlying code of the application and will be able to distribute the apps smoothly.
  3. Any closed-source proprietary application will cost the company a significant amount depending on the number of users and other variables as the best features are accessible when you pay for the premium version. Zoom’s free platform only allows meetings for 40 minutes. 
  4. On the other hand, there is zero upfront cost when you are opting for open-source software instead. 
  5. Moreover, Zoom has been constantly under scrutiny for its security flaws. In April of 2020, over 500,000 Zoom accounts were hacked and were being sold on the dark web and hacker forums. 

For the reasons mentioned above, many people are now looking for an open-source zoom alternative.
