Mumble

Self-Hosted

Open-source low-latency voice chat for gamers and teams

Overview

Mumble is an open-source, low-latency voice communication tool ideal for gamers, teams, and communities. It uses a client-server model (server component: Murmur) with end-to-end encryption for secure conversations. Key features include positional audio (for immersive gaming), fine-grained user permissions, text chat, and cross-platform support. Deployable via Docker, binary packages, or source code, it’s easy to self-host for small groups or scale for large communities—perfect for privacy-focused users avoiding proprietary VoIP apps.

Frequently Asked Questions

? Is Mumble hard to install and self-host?

Mumble’s server (Murmur) is easy for basic setups—options include Docker images, binary installs, or package managers (e.g., apt on Ubuntu). Advanced setups (port forwarding, SSL) need minimal technical skills, and comprehensive documentation helps guide users through the process.

? Is Mumble a good alternative to Discord for gaming?

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.

? Is Mumble completely free to use and self-host?

Absolutely—Mumble is open-source (GPLv3 license) with no subscription fees, premium tiers, or hidden costs. Both the client and Murmur server are free to download, use, and self-host.
