Jami is a viable alternative to Zoom that is designed with the freedom and privacy of users in mind.

One nice security feature for Jami is that it is completely peer-to-peer and doesn't require a server for relaying data between users. Also, users who are on the same local network will be able to communicate even when they are disconnected from the internet. It also can be used without any restrictions on file size, speed, bandwidth, features, number of accounts, storage, or anything else.

Unlike some other similar apps on the market these days, Jami requires no personal information to be provided when creating your account.
