Deploy Mattermost with ServerKit
Team chat built for organizations that can't use SaaS
Open-source alternative to Slack
Mattermost delivers channels, threads, calls, playbooks, and integrations in a package designed for on-premises deployment from day one. It is the default answer for teams whose compliance requirements rule out hosted chat — with no message history limits, ever.

One-click deploy
Mattermost is a ServerKit template: click install, point the link at your own panel, and confirm. ServerKit provisions the containers, volumes, and reverse proxy for you — serverkit.ai never connects to your server.
