TrueConf Server vs. Rocket.Chat

TrueConf Server is an on-premises corporate messenger with powerful video collaboration tools and webinar support. The solution is free for up to 1,000 lifetime users and also offers an enterprise edition tailored for large organizations, government institutions, and defense agencies. Deployed within LAN, it guarantees complete control over communications and access. Installation takes just 15 minutes on Windows or Linux. The platform ensures secure communication with a proprietary protocol and provides a user-friendly address book with presence statuses for colleagues.

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.
