What is rocket.chat?

Rocket.Chat is an open-source communication platform that gives organisations full control over their infrastructure and data. It combines text chat, voice and video in a single interface and can be run on your own servers, including fully air-gapped environments with no internet connection. The freemium model allows you to get started without licensing costs. Running it requires your own servers and technical staff.

Core features

  • Chat, voice and video in one platform, without integrating external services
  • Self-hosting and air-gapped deployment for environments without internet connectivity
  • Zero-trust security model with certifications up to DoD Authority to Operate (ATO) IL6
  • Cross-organisation collaboration, connecting agencies and external partners in shared channels
  • Full customisability through open source code for individual requirements and integrations

Who is rocket.chat for?

Rocket.Chat is aimed at government agencies, defence organisations and operators of critical infrastructure that cannot or are not permitted to outsource chat communication to a cloud provider. Specifically, anyone who needs to demonstrate DoD compliance or maintain communications during disaster response without an internet connection will find Rocket.Chat to be one of the few certified options available.

For small teams without compliance requirements, the platform is over-engineered. Anyone without experience in container infrastructure will face real obstacles even during the initial setup. Ongoing operations, updates and security patching rest entirely with your own team.

Context & alternatives

Rocket.Chat belongs to the category of self-hostable team communication platforms. Comparable open-source projects include Mattermost and Matrix (or Element), which offer similar deployment models. Mattermost also targets high-security environments; Element places greater emphasis on the decentralised Matrix protocol.

The concrete differentiator for Rocket.Chat is its DoD certification up to IL6. Organisations that specifically need this credential for US defence standards will find it a unique selling point that other platforms do not currently offer in this form.
