Fully functioning, free, open-source, end-to-end encrypted, browser-based (install nothing) Facetime-alternative. Stable video and sound, screen share, password protection for rooms and a few other handy features. Highly recommended. No more reason to accept proprietary code that isn't transparent or that reports to three letter agencies.
