# Public URL hosting (Box)
Use this to **put a running service on the public internet** from inside a Box: a web app, an API, a demo, or a long-lived endpoint. Box handles TLS, routing, and auth — no DNS, no certificates, no separate platform.
## Recipe
```bash
box_id="$(box new --no-auto-stop --json | jq -r 'select(.event == "ready") | .id')"
box ssh "$box_id" -- bash -s < ./deploy.sh # build + start app on 0.0.0.0:8080
box ssh "$box_id" -- "host 8080 --public --title 'my app'"
box ssh "$box_id" -- "host url 8080" # https://<box>-8080.on.ascii.dev
```
`host` URLs are token-gated by default; `--public` makes them open. A dedicated IPv4 + full TCP/UDP means you can also point your own domain or host non-HTTP services.
## Why Box
- **Zero infra** — TLS + subdomain + auth managed for you.
- **Stays up** — `--no-auto-stop` keeps the host alive 24-7; persists across resume.
- **Cheap** — per-second billing, ~10× cheaper than typical sandbox/host providers.
## Prereqs
`curl -fsSL https://box.ascii.dev/install | sh`, then `box login "$BOX_API_KEY" --json`.
## Limits
EU-only; 100 active VMs soft cap. For multi-region CDN-grade hosting, use a dedicated host; Box is best for single-VM services, previews, and demos.
