Rocket.Chat is an open-source communication platform that community builders use when they need complete control over their data and infrastructure. Unlike hosted solutions like Discord or Slack, it allows communities to deploy messaging, voice, and video on their own servers or air-gapped environments. This makes it particularly valuable for professional communities, developer communities, and membership organizations that handle sensitive information or operate under strict compliance requirements.
