Jitsi

In today’s digital world, online meeting and video conferencing tools have become essential components of communication between individuals and institutions. While many of these tools offer proprietary and licensed architectures, open-source solutions like Jitsi are preferred for their freedom, customizability, and data privacy. Jitsi contributes to the free software ecosystem by providing secure and customizable video conferencing capabilities in both on-premises and cloud-based environments.

What is Jitsi?

Jitsi is an open-source video conferencing software project initiated in 2003 and currently maintained by 8x8 Inc. Originally developed as a SIP-based desktop client, Jitsi evolved over time into a powerful browser-based conferencing system powered by WebRTC technology. Today, its most widely used component, Jitsi Meet, enables instant video calls directly through a web browser without requiring any software installation.

Jitsi is suitable for both individual users and enterprise solutions due to its architecture that prioritizes user privacy and its customizable structure.

Core Components

The Jitsi ecosystem consists of multiple components:

• Jitsi Meet: A web-based interface for video meetings.
• Jicofo (Jitsi Conference Focus Component): Manages conference control, user participation, and resource allocation.
• Jitsi Videobridge: A video bridge that routes media data with low latency.
• Prosody: An XMPP (Jabber) server that provides authentication and messaging infrastructure.
• Coturn: A TURN/STUN server that facilitates connections for users behind NATs or firewalls.

Together, these components deliver a robust and secure end-to-end video conferencing infrastructure.

Use Cases

• Education: Used by schools and universities as a remote learning infrastructure.
• Internal Meetings: Companies run Jitsi on their own servers to ensure secure meetings while preserving data privacy.
• Communities and Civil Initiatives: Frequently adopted by open-source communities and NGOs.

Security and Privacy

Jitsi strives to guarantee secure communication through support for E2EE (end-to-end encryption). Additionally, when servers are owned by the user, data remains entirely within the local network and is not transmitted to external services. This architecture offers a significant advantage for institutions seeking compliance with data protection regulations such as GDPR in Europe.

Customization and Easy Deployment

Jitsi can be rapidly deployed using Docker containers and customized according to organizational needs, including logos, user interface elements, and routing options. It also integrates with authentication systems such as LDAP/AD, OAuth2, and SAML.

Distributed Architecture and Load Balancing

In high-traffic systems, Jitsi improves performance by distributing load across multiple JVB (Jitsi Videobridge) instances. As traffic increases, additional bridges are activated, enabling a scalable architecture. This feature makes it possible to manage large-scale meetings effectively.

Comparison with Other Solutions

Jitsi offers a flexible, secure, and customizable video conferencing solution grounded in the free software philosophy. It serves as an alternative for individuals and institutions seeking to deploy their own infrastructure and manage user data without external dependencies.
