What's installed on your Mumble server?
- Mumble server 1.5 from the project's official Docker image
- SuperUser admin account with a password generated during setup
- A root channel named Seturack and a welcome message, both yours to change
- Persistent storage, so channels and settings survive restarts
- Ports 64738/TCP and 64738/UDP for voice and text, plus port 22 for SSH
What size do you need for Mumble?
Mumble's documentation doesn't give a RAM figure, and the project's site says hosting has a low resource cost. As a rule of thumb, 1 GB is plenty for a small or mid-sized community. Look at 2 GB or 4 GB if the same machine will also run a game server or another app. The real load is on the network: the default setting caps each user's speech at 558 kbit/s, and unlimited traffic is included in the price.
| Use | Size | Price | Choose |
|---|---|---|---|
| Small team | 1 GB RAM · 1 vCore · 25 GB NVMe | $2.58/mo | |
| Clan | 2 GB RAM · 1 vCore · 40 GB NVMe | $4.01/mo | |
| Large community | 4 GB RAM · 2 vCore · 60 GB NVMe | $6.89/mo |
Who is it for?

Good to know
- The server starts with no join password, so anyone with the address can connect. To set one, write the password on the MUMBLE_KATILIM line in /opt/seturack/mumble/.env and run docker compose up -d in the same folder.
- The panel password belongs to SuperUser. Use your own name day to day and give admin rights through the admin group.
- The server's certificate is self-signed, so your client may ask you to accept it on the first connection.
- The default config allows up to 100 users at once. To raise it, add MUMBLE_CONFIG_USERS to compose.yaml.
- Official clients cover Windows, macOS and Linux. For phones the site lists third-party apps, and its iOS app hasn't been updated since 2017.
- The server doesn't update itself. For a newer 1.5 release, run docker compose pull and docker compose up -d in /opt/seturack/mumble.
Mumble questions and answers
How do I connect to my Mumble server?
In the Mumble client, open Connect from the Server menu and click Add New. Enter the connection address from your panel, use 64738 as the port and pick a username. Unless you've set a password, you don't need anything else.
How much RAM does a Mumble server need?
There's no official figure, and the project's site says hosting has a low resource cost. As a rule of thumb, 1 GB is plenty for a small or mid-sized community. Look at 2 GB if the same machine runs other work too.
How many users can a Mumble server handle?
The config file defaults to 100 users at once, with no per-channel limit, and you can change this with the users setting. The real ceiling depends on how many people talk at the same time and on the network, so there's no fixed number.
Do I need a license to run Mumble?
No. Mumble is free, open-source software, and neither the server nor the client asks for a license key. You pay only for the server itself, with no extra charge based on the number of users.
How do I create channels and give admin rights in Mumble?
Connect as SuperUser with the panel password, right-click the root channel and add a new one. Permissions live on the ACL and Groups tabs of a channel's Edit screen. The admin group on the root channel carries over to other channels.
Is Mumble voice chat encrypted?
The project's site says communication is always encrypted and that authentication uses public and private keys by default. The client creates its own certificate when you first start it, so there's nothing extra for you to set up.
