Run the Nodmix Gateway on any Linux server or cloud VPS. This page helps you
pick a provider, explains how cloud deployments work, and covers generic Linux
tuning that applies everywhere.

**AWS (EC2 / Lightsail / free tier)** also works well.

## How cloud setups work

- The **Gateway runs on the VPS** and owns state + workspace.
- You connect from your laptop or phone via the **Control UI** or **Tailscale/SSH**.
- Treat the VPS as the source of truth and **back up** the state + workspace regularly.
- Secure default: keep the Gateway on loopback and access it via SSH tunnel or Tailscale Serve.
  If you bind to `lan` or `tailnet`, require `gateway.auth.token` or `gateway.auth.password`.

## Harden admin access first

Before you install Nodmix on a public VPS, decide how you want to administer
the box itself.

- If you want Tailnet-only admin access, install Tailscale first, join the VPS
  to your tailnet, verify a second SSH session over the Tailscale IP or
  MagicDNS name, then restrict public SSH.
- If you are not using Tailscale, apply the equivalent hardening for your SSH
  path before exposing more services.
- This is separate from Gateway access. You can still keep Nodmix bound to
  loopback and use an SSH tunnel or Tailscale Serve for the dashboard.

Tailscale-specific Gateway options live in [Tailscale](/gateway/tailscale).

## Shared company agent on a VPS

Running a single agent for a team is a valid setup when every user is in the same trust boundary and the agent is business-only.

- Keep it on a dedicated runtime (VPS/VM/container + dedicated OS user/accounts).
- Do not sign that runtime into personal Apple/Google accounts or personal browser/password-manager profiles.
- If users are adversarial to each other, split by gateway/host/OS user.

Security model details: [Security](/gateway/security).

## Using nodes with a VPS

You can keep the Gateway in the cloud and pair **nodes** on your local devices
(Mac/iOS/Android/headless). Nodes provide local screen/camera/canvas and `system.run`
capabilities while the Gateway stays in the cloud.

Docs: [Nodes](/nodes), [Nodes CLI](/cli/nodes).

## Startup tuning for small VMs and ARM hosts

If CLI commands feel slow on low-power VMs (or ARM hosts), enable Node's module compile cache:

```bash
grep -q 'NODE_COMPILE_CACHE=/var/tmp/nodmix-compile-cache' ~/.bashrc || cat >> ~/.bashrc <<'EOF'
export NODE_COMPILE_CACHE=/var/tmp/nodmix-compile-cache
mkdir -p /var/tmp/nodmix-compile-cache
export NODMIX_NO_RESPAWN=1
EOF
source ~/.bashrc
```

- `NODE_COMPILE_CACHE` improves repeated command startup times.
- `NODMIX_NO_RESPAWN=1` keeps routine Gateway restarts in-process, which avoids extra process handoffs and keeps PID tracking simple on small hosts.
- First command run warms the cache; subsequent runs are faster.
- For Raspberry Pi specifics, see [Raspberry Pi](/install/raspberry-pi).

### systemd tuning checklist (optional)

For VM hosts using `systemd`, consider:

- Add service env for a stable startup path:
  - `NODMIX_NO_RESPAWN=1`
  - `NODE_COMPILE_CACHE=/var/tmp/nodmix-compile-cache`
- Keep restart behavior explicit:
  - `Restart=always`
  - `RestartSec=2`
  - `TimeoutStartSec=90`
- Prefer SSD-backed disks for state/cache paths to reduce random-I/O cold-start penalties.

For the standard `nodmix onboard --install-daemon` path, edit the user unit:

```bash
systemctl --user edit nodmix-gateway.service
```

```ini
[Service]
Environment=NODMIX_NO_RESPAWN=1
Environment=NODE_COMPILE_CACHE=/var/tmp/nodmix-compile-cache
Restart=always
RestartSec=2
TimeoutStartSec=90
```

If you deliberately installed a system unit instead, edit
`nodmix-gateway.service` via `sudo systemctl edit nodmix-gateway.service`.

How `Restart=` policies help automated recovery:
[systemd can automate service recovery](https://www.redhat.com/en/blog/systemd-automate-recovery).

For Linux OOM behavior, child process victim selection, and `exit 137`
diagnostics, see [Linux memory pressure and OOM kills](/platforms/linux#memory-pressure-and-oom-kills).
