Rocket.Chat

Rocket.Chat is an open-source, self-hostable team communication platform that gives organizations a secure, customizable alternative to closed messaging tools — one they can run on their own infrastructure and fully control. It's especially popular with security-conscious organizations, governments, regulated industries and technical teams that need the collaboration features of modern chat but cannot or prefer not to send their communication through a third-party cloud service. By being open source and self-hostable, Rocket.Chat puts control over data, security and customization in the organization's hands.

The platform provides the messaging capabilities teams expect: channels, direct messages, threads, file sharing, search, and voice and video conferencing, plus integrations and bots to connect it with other systems. Because it's open source, organizations can self-host it on-premises or in their own cloud, customize and extend it deeply, integrate it with internal tools, and meet strict security, privacy and compliance requirements without depending on an external vendor's policies. It also supports features like end-to-end encryption and granular controls that matter for sensitive environments, and can even power customer-facing communication channels.

Rocket.Chat's combination of open source, self-hosting, security and flexibility makes it a serious choice for entities with demanding requirements around data sovereignty and control — and for any team that values owning its communication infrastructure and avoiding lock-in. It's used across government, defense, healthcare, finance and technology, as well as by communities and companies that prefer open, customizable tools. As concerns about data privacy, security and dependence on big platforms grow, open-source, self-hostable communication tools are increasingly important. For organizations that need secure, customizable team communication they can fully control and host themselves, Rocket.Chat offers a powerful, flexible and trustworthy solution.
