Our take
Built for organizations, not individuals, and that framing matters before you pick it. The default tags here say unencrypted, so treat it as a self-hosted Slack alternative for team collaboration rather than a private messenger. Choose it when you need to own your company’s chat infrastructure; skip it if end-to-end privacy between two people is the goal.
