Can Mattermost and Slack talk in both directions?

Yes. Build one flow that starts in Mattermost and acts in Slack, and a second that runs the other way, in the same project.

On our EU cloud in Frankfurt, or self-hosted on your own infrastructure with Docker or Kubernetes. The MIT-licensed core means there is always an exit.

Connect Mattermost to Slack

Move data between Mattermost and Slack the moment it happens. Build the flow visually, or let AI write it for you, then run it on our cloud or your own infrastructure.
