Strong encryption and certificate-based authentication
Full self-hosting control over data and server uptime

Cons
Dated interface compared to modern chat apps like Discord
Requires self-hosting or a paid third-party host, unlike free-to-join platforms
Smaller ecosystem of integrations, bots, and community features than Discord
Initial server setup and configuration can be technical for non-technical users
No built-in text-first community features like servers with public discovery

Strong fit for regulated industries, government and defense customers
Playbooks provide built-in workflow automation not native to Slack
Deep integrations with developer and DevOps tooling
Lightweight architecture (single Go binary) makes self-hosting comparatively simple
Cons

Enterprise pricing is custom-quoted and not publicly transparent
Self-hosting requires ongoing server maintenance and updates
UI and mobile experience is generally considered less polished than Slack
Annual prepaid billing only for official Professional and Enterprise licenses, no monthly option
Use Cases
Mumble
Competitive gaming voice comms — A gaming clan needs extremely low-latency, reliable voice chat during matches without a third party controlling their server.
Self-hosted community voice server — A privacy-conscious community wants to run its own voice server instead of depending on a commercial platform's infrastructure.
Lightweight team coordination — A small team wants simple, low-resource voice channels for coordination without the overhead of a full chat platform.
Mattermost
Incident response and DevOps workflows — Engineering teams use Playbooks to coordinate incident response with automated checklists and dedicated channels.
Regulated and government communication — Public-sector and financial-services organizations need self-hosted or air-gapped messaging to meet compliance requirements.
Secure internal team chat — Organizations that want Slack-like messaging while keeping full control of where data is stored.
