Files and calls add to it. See plans ## Team chat that stays inside the company Decisions, files and incident chats are company knowledge. Keep them on a server you control, with the retention you choose. ### Channels and threads Public and private channels, direct messages and threads keep conversations organised by team, project or incident. ### Encryption and federation Matrix with Element encrypts private rooms end to end and can federate with partner organisations on their own servers. ### Calls built in Mattermost Calls and Element Call add voice, video and screen sharing; run Jitsi Meet next to them for larger meetings. ### Integrations Webhooks, bots and slash commands connect chat to your monitoring, Git server and automation tools such as n8n. ### Your data on your server Customer records, conversations and reports stay on a server you control, in the location you choose. ### Root access, your rules Every Linux VPS, VDS and dedicated server comes with full root access: you choose the versions, the add-ons and the security settings. ### Backups included Free weekly and monthly backups come with every VPS and VDS plan. For data that changes every day, keep copies of your own as well. ### Locations on three continents Run your server in the United States, Europe or Asia, close to the people who use it. The order form estimates the latency from where you are to each location. ## Set up team chat in four steps Order the app preinstalled on your server, or install it yourself with our guide.

Mattermost for engineering and operations teams who want a Slack-like workspace with many integrations. Rocket.Chat when chat should also handle customer conversations through its omnichannel features. Matrix with Element when you need end-to-end encryption, federation with other organisations or bridges to other chat networks. ### Can I import our history from Slack? Mattermost and Rocket.Chat can import a Slack export with their import tools, including channels, users and messages. Matrix connects to Slack and other networks through bridges instead. Test the import on a staging server first. ### How is Mattermost installed for production? From Mattermost’s packages for Ubuntu, Debian and RHEL or from its tarball, with PostgreSQL 14 or newer and a reverse proxy in front. Mattermost does not support Docker Compose for production, and MySQL is deprecated since version 11. ### What does Rocket.Chat need? Docker Compose with Rocket.Chat and MongoDB 8, set up as a replica set, with ROOT\_URL set to your full https address. Rocket.Chat recommends 2 vCPU and 4 GB of RAM each for the app and the database, and Ubuntu 24.04. Never expose MongoDB’s port 27017 to the internet. ### What should I know before starting a Matrix server? The server name becomes part of every user ID and cannot be changed later, so choose it first; with .well-known delegation, IDs can use your main domain while Synapse runs on a subdomain. Use PostgreSQL rather than SQLite, and serve Element Web as the browser client. ### Do mobile push notifications work on a self-hosted server? Yes. Notifications to iOS and Android go through each project’s push gateway, because only the app makers can talk to Apple’s and Google’s push services. Each project documents how to set up its push notifications. ## Ready to bring your team chat home? Tell us what you want to run and for how many people, and we will help you pick the right server.
