Rocket.Chat is an open-source team communication platform. You run it on your own server, and your team gets channels, direct messages, group chats, threads, voice and video calls, and file sharing, all under your control. It suits companies and teams that want a Slack-style tool without paying per user or sending their messages to a vendor’s cloud. It also suits support and sales teams, because customer-facing chat is built in, not bolted on.
What is Rocket.Chat?
Rocket.Chat is a chat server plus web, desktop, and mobile apps. The server is open source (MIT license) and has been under active development since 2015. You can install it with Docker or a snap package, or use one of the managed hosting options. Your messages live in a database you control, and you decide who can register, which integrations run, and how long history is kept.
Under the hood it is a Node.js application backed by MongoDB. That stack is well documented, and there is a large community around it, so answers to common setup problems are easy to find.
What is Rocket.Chat used for?
- Internal team chat. Channels keep conversations organized by project or department, and threads and discussions keep topics readable instead of letting one channel scroll into noise.
- Voice and video calls. You can start a call inside any channel or direct message. Small calls run on the built-in WebRTC engine, and you can connect Jitsi Meet for bigger meetings.
- Customer support chat. The omnichannel inbox turns Rocket.Chat into a helpdesk. Website live chat, email, WhatsApp, Facebook Messenger, and Telegram messages arrive in one queue for your agents.
- Partner and guest access. You invite external people into specific channels or private rooms, so a project with a client or supplier does not live in someone’s personal email.
- Automation and alerts. Incoming and outgoing webhooks, a REST API, and an app marketplace let you pipe CI results, monitoring alerts, and CRM events into the rooms where people act on them.
- Federated communication. Rocket.Chat can federate over the Matrix protocol, so two organizations on different servers can talk to each other in shared rooms.
Key features
- Channels, discussions, and threads. Public channels for open teams, private groups for sensitive work, and threads that keep side conversations out of the main flow.
- Voice and video calls. One click starts a call in any conversation, with screen sharing on the desktop apps.
- Omnichannel inbox. Live chat widgets and messaging apps feed a single agent queue with routing,SLA tags, and canned responses.
- App marketplace and integrations. Hundreds of installable apps plus webhooks and a full REST API cover most integration needs.
- Fine-grained permissions. Custom roles control who can post, invite, manage channels, or access admin settings.
- End-to-end encryption option. Private rooms can enable E2EE. It is off by default, and it disables search and some integrations, which is the honest trade-off.
Rocket.Chat on OpenSysLab
Every OpenSysLab server is a private virtual machine in the region you chose at purchase. The app installs automatically in about ten minutes, and the Vibe-code agent inside Open WebUI can read, configure, and manage it for you, you just connect your own AI API key. Servers start at $6/month. See the Rocket.Chat product page for plans and regions.
The bottom line
Rocket.Chat is one of the most complete self-hosted chat platforms you can run today, and the open-source edition is genuinely usable without a paid plan. The trade-off is that you operate a MongoDB-backed service, which is real work unless someone else handles it for you.
