# General FAQ

> Common questions about what Suji is, how it's billed, and what runs where.

## What is Suji?

Suji gives you **dedicated Linux VMs in EU data centers, billed by the hour**. Use a VM as a plain server — SSH in, run whatever you want — or deploy apps onto it in one click from the marketplace. Either way, the dashboard gives you a web terminal, file editor, live logs, firewall, metrics, and snapshots, and we handle the VM, the OS image, storage, HTTPS ingress, and billing.

Each customer gets their **own dedicated VM** — no shared runtime, no noisy neighbors.

## Do I have to use the marketplace?

No. The marketplace is a convenience, not a requirement. A Suji VM is a full Linux machine with root access — install anything yourself over SSH or the web terminal. Marketplace apps just give you a managed install/upgrade/uninstall flow and an HTTPS URL out of the box.

## How am I billed?

Hourly, per-VM, from a prepaid credit balance. No subscriptions, no fixed monthly fee. Add credit before you create a VM. See [Billing & credits](/concepts/billing-credits) for the full lifecycle.

Note: **stopping a VM does not reduce the bill** — a stopped VM bills the same as a running one. Only destroying a VM stops its charges.

## What apps are in the marketplace?

Today: **OpenClaw, n8n, Ghost, NocoDB, Plausible, Wiki.js, Minecraft**. The catalog grows over time — see [Marketplace overview](/marketplace/overview) for the current list and per-app guides.

## How is my data isolated?

* **Dedicated VM per customer** — your apps share *your* VM but never share with other customers.
* **Encrypted disks** at the storage layer.
* **No shared filesystem** between tenants.
* **Authenticated management channel** — the dashboard reaches your VM only over an encrypted connection unique to it.
* **Audit log** records every change.

See the [Security FAQ](/faq/security) for the full picture.

## Where are VMs hosted?

EU data centers. You pick from:

* Falkenstein, Germany
* Nuremberg, Germany
* Helsinki, Finland

All disks and backups stay in the EU.

## Can I use my own domain?

Yes. Apps come with a `*.suji.fr` HTTPS URL out of the box, and you can attach a domain you own to any exposed app from the dashboard. Add the custom domain, prove ownership with a one-line `TXT` record, then point an `A` record at your VM's IP and pick a mode: **Cloudflare** (front the VM with your own Cloudflare account — DDoS/WAF protection, SSL set to Full) or **Direct** (point straight at the VM, with an automatic Let's Encrypt certificate). See [Custom domains](/manage-vm/custom-domains) for the full walkthrough, the trade-offs between the two modes, and apex + www setup.

## Can I install software that isn't in the marketplace?

Yes — it's your VM. SSH in (or use the web terminal) and install anything. Self-installed software won't appear in the dashboard's app management and won't get an automatic `*.suji.fr` URL, but it runs like on any Linux server, and you control the firewall.

## What happens when my credit runs out?

It depends on whether **auto-recharge** is enabled:

* **Auto-recharge ON + card declined:** the VM is paused (`suspended`) and stays recoverable for as long as your remaining credit covers it. Fix the card and click **Resume**.
* **Auto-recharge OFF and balance hits €0:** the VM is terminated. A snapshot is taken automatically and kept for **7 days** — top up inside that window and restore to recover your data. Volumes and manual snapshots get the same 7-day window, and topping up in time keeps them.

See [When your credit runs low](/billing/grace-period) for the full timeline.

## Can I export my data?

Yes:

* **Files**: download anything from the Files tab or via SSH.
* **Snapshots**: full VM snapshots you can restore from at any time.
* **App data**: each app has its own export path (database dumps, config files, …). Use the terminal to run them.
* **Account data**: export a copy from **Settings → Data** in the dashboard.

## How do I get help?

* **Anything Suji** (VMs, billing, dashboard, app installs) → open a support ticket from your dashboard.
* **App-specific usage questions** → see the app's page under [Marketplace](/marketplace/overview); each app is open-source software with its own documentation and community.
* **Sales / partnerships** → `support@suji.fr`.
