Rocket.Chat is a collaboration platform that supports real-time chat, voice and video calls, customer-engagement across channels (live chat, WhatsApp, etc.), and lets you deploy either cloud-hosted or self-hosted (on-premises) depending on your needs.
If you’re a founder, ops or dev-team who cares about data ownership, customization, and security (rather than being locked into a closed proprietary chat system), Rocket.Chat gives you a flexible alternative. It helps you reduce reliance on SaaS tools that store your data externally, and gives you more control over how your communication stack works. It’s especially relevant for companies in regulated industries, with internal collaboration needs or customer-engagement workflows.
You deploy a workspace (either their cloud service or your own server). Users join channels and direct messages, share files, make voice/video calls, integrate with other systems (APIs, SDKs, webhooks). There are “community” (free open-source) versions and paid plans with extra features (hosting, support, advanced security, compliance).
