What you get
Mumble Server runs on a subscription — a pool of CPU, memory and disk that you own. Deploying it takes one click, and the same pool will run your other apps at no extra charge.
A hostname with HTTPS, immediately
Your app is reachable the moment it finishes deploying, on a certificate we issue and renew. Point your own domain at it whenever you like.
Nothing exposed but the app
Only Mumble Server itself gets a public port. Anything it depends on stays on a private network unreachable from the internet.
A shell and SFTP
A real shell in the container and SFTP for its files. This is not a black box — if you want to get in and look, you can.
Updates you control
We check nightly for a new image and tell you when one lands. Applying it is your decision, per app, and a failed update rolls back to the exact image it replaced.
A free snapshot
One full archive of Mumble Server included, restorable in a click. Keep more with the snapshots add-on.
Your data, exportable
SFTP access to everything the app stores. Nothing here is locked in.
What actually runs
No mystery images. Mumble Server deploys 2 containers, and these are exactly the ones:
mumblevoip/mumble-server:v1.5.901supportnginx:1.31.3web
Running Mumble Server yourself vs. running it here
Mumble Server is free software and you can absolutely run it yourself — we would rather tell you that than pretend otherwise. What you are paying for here is the part around it.
On your own server
- You write the compose file and keep it working
- You configure a reverse proxy and renew certificates
- You watch for new releases and apply them
- You own the backups, and finding out they were broken
On Caliber Node
- One click, and it is running on HTTPS
- Certificates issued and renewed for you
- Update checks nightly, applied when you say so
- A free snapshot, restorable in a click
Questions about Mumble Server hosting
- Can I try Mumble Server for free?
- Yes. Every new account gets $5.00 of Cloud Apps credit, applied automatically to your first invoice -- there is no code to enter and no card trial to cancel. On the plan Mumble Server needs, that covers your first 2 months.
- How do I install Mumble Server?
- Pick Mumble Server from the catalog and deploy it. There is no compose file to write, no server to prepare and no reverse proxy to configure. It comes up on a hostname with HTTPS already working.
- What does hosting Mumble Server cost?
- Mumble Server needs at least 512 MB memory, so the Nano subscription at $2.50/mo is the smallest that fits it. That size is a close fit for Mumble Server on its own -- if you want to run other apps alongside it, take the next plan up and share the pool.
- Do I get access to the Mumble Server files and database?
- Yes. Every app has a browser shell into its container, SFTP for its files. Your data is yours and you can take it out whenever you want.
- Are updates to Mumble Server automatic?
- Only if you turn them on. We check nightly for a new image and tell you when one exists, but applying it is your call, per app.
- Can I use my own domain for Mumble Server?
- Yes. Every app gets a hostname on our domain immediately, and you can point your own domain at it instead. Certificates are issued and renewed automatically either way.
- Can I back Mumble Server up?
- Every app includes one free snapshot -- a full archive of its data you can restore from. Keeping more than one is a paid add-on on the subscription.
