# International and China sites, and how to choose

> Aria Compute runs as two independent deployments (.com and .cn) with separate accounts, wallets, payments, and release hosts. Learn what differs.

Aria Compute is deployed as two independent regions with the same code and different data. Every account, wallet, API key, and payment record belongs to exactly one region.

## Side by side

|                   | International             | China                    |
| ----------------- | ------------------------- | ------------------------ |
| Marketing site    | `ariacompute.com`         | `ariacompute.cn`         |
| Gateway           | `gateway.ariacompute.com` | `gateway.ariacompute.cn` |
| Docs              | `docs.ariacompute.com`    | `docs.ariacompute.cn`    |
| Currency          | USD (\$)                  | CNY (¥)                  |
| Payment providers | Stripe                    | WeChat Pay, Alipay       |
| Release host      | GitHub (`ariacompute/*`)  | Gitee mirror             |
| OAuth             | Google, GitHub, WeChat    | GitHub, WeChat           |
| Default language  | English                   | Simplified Chinese       |

## Language and site defaulting

The frontend detects your site with IP geolocation (backed by a MaxMind GeoLite2 database) and defaults the language accordingly. You can override the language through the site's language switcher; the default language just omits the `?lang=` query parameter. Thirteen languages are supported: English, Simplified Chinese, Traditional Chinese, Spanish, French, German, Italian, Russian, Japanese, Korean, Portuguese, Arabic, and Hindi.

The site itself is switched by domain, not by language: `ariacompute.com` and `ariacompute.cn` are separate deployments with separate databases.

## What is not shared

* **Accounts**: sign up on each site you use.
* **Wallets**: top up each site separately, in its currency.
* **API keys**: a `bfvk-` key on `.com` cannot authenticate against the `.cn` gateway.
* **Invoices and receipts**: China issues e-invoices (电子发票); international issues Stripe receipts.
* **Release assets**: the Downloads page on `.com` pulls from GitHub; on `.cn` it pulls from Gitee.

## Choosing a site

Pick the site closest to where your users and payment method live. If you need both, create parallel accounts and manage keys per region.
