Open-source Microsoft Teams alternative: Mattermost and Jitsi
Updated 7/19/2026
Microsoft Teams combines team chat with video conferencing, but it comes tied to a 365 license and with limits. You can get the same with two open-source apps, on your own server.
Team chat: Mattermost or Rocket.Chat
Mattermost and Rocket.Chat offer channels, direct messages, threads, search and integrations, just like Teams or Slack. The difference: they run on your server, with no message history limit and no per-user cost.
Video calls: Jitsi Meet
Jitsi Meet gives you encrypted video calls with screen sharing, no account required and none of the time limits of free commercial tiers. It installs with automatic HTTPS on your server subdomain.
Who it is for
Ideal for companies that want full control of internal communication, GDPR compliance and no subscriptions that grow with the team. You can run both apps on the same VPS or on separate servers.
How to install them
Pick Mattermost (or Rocket.Chat) and Jitsi Meet from the one-click app catalog. For smooth video, choose a plan with more CPU, since video traffic uses resources.
Put this guide into practice on your own VPS
EU cloud servers, billed hourly, ready in minutes, with one-click installs for dozens of apps.
