Rocket.Chat vs. CometChat

Trusted by the world's most critical organizations, Rocket.Chat Secure CommsOS® is built for high-consequence environments to deliver decision advantage: the ability to work together, verify access continuously, and keep every action auditable across agencies, borders, classification levels, and connected systems. It federates natively across protocols like Matrix and XMPP, so partners never have to adopt your system to work with you. Deploy anywhere — self-hosted, air-gapped, or in a sovereign cloud — for chat, voice, video, and governed AI agents, entirely under your control.
