Rocket.Chat
Rocket.Chat is an open-source team communication platform that gives you a Slack-style workspace you fully control. With data protection and self-hosting at its core, it is one of the most widely deployed open-source alternatives to proprietary messaging tools, used by organisations that need their conversations to stay on their own infrastructure.
Key Features
- Self-hosted workspaces — Deploy on your own servers or in your cloud, keeping all messages and files under your control.
- Channels and direct messages — Organise conversations into public and private channels, groups, and one-to-one threads.
- Video and voice conferencing — Built-in audio and video calls with screen sharing for remote meetings.
- Enterprise integrations — LDAP, Active Directory, SAML, and OAuth single sign-on for existing user directories.
- Bots and automation — A rich API and bot framework for workflows, notifications, and custom integrations.
- File sharing and search — Drag-and-drop file transfer with full-text message and file search.
- Omnichannel support — Live chat, email, and social messaging in one inbox for customer-facing teams.
Why Use Rocket.Chat?
Rocket.Chat is the natural choice when your team needs the productivity of a modern chat app without surrendering data to a third-party provider. It runs on your own hardware, scales from small teams to large organisations, and the permissive licence means you are never locked in.
