Tox (qTox) vs WhatsApp
Side-by-side comparison of features, pricing, ratings, and alternatives.
Tox is an open, peer-to-peer messaging protocol built to let people communicate without anyone else listening in, and without relying on centralized servers that could be compromised or monitored. Official and community clients built on the protocol - including qTox for desktop, Toxic for Linux terminals, and aTox for Android - provide encrypted instant messaging, voice and video calls, screen sharing, and file transfers with no artificial size limits. Tox is completely free and comes with no advertising, ever, and is developed openly by its user community rather than a company. Its distributed network architecture means there is no central point of failure or control, and both the protocol and its libraries are free and open source.
WhatsApp is a globally dominant messaging app offering end-to-end-encrypted text, voice, and video, plus business tools. Its ubiquity makes it the default communication channel in many countries.
