Jitsi Meet
Free cross-platform videoconferencing softwareJitsi is a free-software videoconferencing platform with client applications for Web, desktop, and mobile operating systems.
-
Free Software: Free (as in freedom, not price) software puts the user in control by allowing you to use the software for any purpose, modify it, and redistribute it. This also implies that you can examine the source code and see what it does and how it works. This represents a baseline requirement for recommendation in this guide.
All of the official Jitsi Meet clients as well as the server software are freely licensed.
-
Decentralized: Decentralized systems lack a central authority or gatekeeper. Decentralized systems are more resilient and resistent to censorship and commercial takeover.
Jitsi Meet can be self-hosted. When you use Jitsi Meet, you connect to a given instance (server), whether it be the flagship instance (meet.jit.si), a community-run instance, or an instance running on your own Web server. Instances do not interoperate with one another—all participants must connect directly to the same instance to participate in a meeting.
-
End-to-End Encryption (E2EE): Allows two or more end-points to communicate confidentially, such that no one in the middle (including the service operator) has access to the contents of the communication. This represents a baseline requirement for recommendation in this guide.
One-on-one meetings are E2EE by virtue of being peer-to-peer. For meetings of three or more participants, video and audio data is routed through the Jitsi Meet instance and is not protected by E2EE by default. It is possible to opt into E2EE by setting a meeting password when creating the meeting.
-
Does Not Limit Metadata: Metadata is "data about data." In the context of communication, metadata could represent information about who sent or received a message and at what date and time.
Jitsi Meet is not designed to conceal meeting or participant metadata from the instance operator. Of course, this is less of a concern if you self-host, since such data will be available only to your own instance.
-
Allows Anonymous or Pseudonymous Use: Does not require revealing personally identifiable information (PII) in order to communicate.
Depending on how your instance is configured and the settings specific to your meeting, anyone with a link to the meeting (and optionally a meeting password) can join without an account and without providing any contact information. Some public instances, such as the flagship instance (meet.jit.si), may require an account to start a meeting, however.
