Frequently Asked Questions
? Is Mumble hard to install and self-host?

Yes—Mumble excels at low-latency voice chat (critical for gaming) and offers stronger privacy (self-hosted + E2EE) than Discord. While it lacks Discord’s streaming/bot features, it’s perfect for users prioritizing performance and data control over extra bells and whistles.
