+# VPS hosting
+
+This hub links to the supported VPS/hosting guides and explains how cloud
+deployments work at a high level.

+## Pick a provider

+- **Railway** (one‑click + browser setup): [Railway](/railway)
+- **Fly.io**: [Fly.io](/platforms/fly)
+- **Hetzner (Docker)**: [Hetzner](/platforms/hetzner)
+- **exe.dev** (VM + HTTPS proxy): [exe.dev](/platforms/exe-dev)
+
+## How cloud setups work
+
+- The **Gateway runs on the VPS** and owns state + workspace.
+- You connect from your laptop/phone via the **Control UI** or **Tailscale/SSH**.
+- Treat the VPS as the source of truth and **back up** the state + workspace.

+
+## 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.
