Jitsi Meet is a videoconferencing application with features like the ability to password-protect your meetings or remove people off a conference. But what sets it apart from most well-known videoconferencing services is that it's free and can run entirely on your own computer hardware. You can also download the video bridge software and use it to host video conferences that friends and colleagues can join through their web browser. Jitsi Meet can't snoop on your conversation because it does not have access to your computer. And because it's open source, you can inspect the code to make sure there aren't any back doors.
