Mumble – Voice Chat Without License Costs

Voice connections with minimal latency – fully open source.
With Mumble, we operate low-latency voice communication with no licensing concerns: server and clients are available under a free license, with no restrictions on commercial use.

Mumble or TeamSpeak?​

Both tools cover a similar need: low-latency voice communication with channels and permission management. The key difference lies in licensing: Mumble is fully open source (BSD license) and usable commercially without restriction, while TeamSpeak requires a license for commercial use. If you're not yet committed to either platform, we generally recommend Mumble. We're happy to advise on the right choice for you.
