Jitsi

Jitsi is a free, open-source video conferencing and real-time communications platform. It provides secure peer-to-peer video calls, group video conferencing, screen sharing, and chat capabilities without requiring accounts or logins. Jitsi is used by individuals, teams, educators, and organizations who value privacy and the ability to self-host. The platform is supported by a non-profit foundation and is available as a web-based service (Jitsi Meet), desktop applications for macOS, Windows and Linux, and mobile apps for iOS and Android. It is particularly valued for its simplicity, security-focused design, and lack of per-participant licensing fees.
