# Regions & data residency

> Waniwani runs in two regions — EU and US. You pick where an organization's data lives when you create it, and everything for that org stays on that stack.

Waniwani runs in **two regions**, EU and US. Each is an independent stack with its own database: an organization's data lives entirely in the region you choose and never crosses to the other.

| Region | Dashboard                    | MCP server                       |
| ------ | ---------------------------- | -------------------------------- |
| **US** | `https://app.waniwani.ai`    | `https://mcp.waniwani.ai/mcp`    |
| **EU** | `https://eu.app.waniwani.ai` | `https://eu.mcp.waniwani.ai/mcp` |

## Choosing a region

You choose a region **when you create an organization**. Before the org-creation wizard runs, Waniwani prompts you to pick your **data residency**:

* **EU** — for teams that need European storage and processing (EU residency requirements).
* **US** — for US-based teams and global teams without EU residency needs.

Your choice applies to **that organization**. Everything downstream — the workspace, members, environments, API keys, conversations, analytics, and stored content — is created on the region's stack and stays there.

<Note>
  Data residency is set per organization and can't be changed after creation. If you need both regions, create a separate organization on each stack.

## Signing in

Sign in on the dashboard for the region your organization lives in:

* **US:** [app.waniwani.ai](https://app.waniwani.ai)
* **EU:** [eu.app.waniwani.ai](https://eu.app.waniwani.ai)

The US dashboard won't show organizations that live in the EU, and vice versa. If you pick a region during onboarding that differs from the stack you signed in on, Waniwani moves you to the right stack and you continue there — your account (email, name, linked sign-in providers) is portable, but sessions and org data always stay local to each region.

## Connecting AI clients

The [Waniwani MCP server](/mcp-server/overview) — the one that lets an AI client operate the platform for you — is also regional. Use the MCP URL for the region your data lives in, and sign in on the matching stack:

* **US:** `https://mcp.waniwani.ai/mcp`
* **EU:** `https://eu.mcp.waniwani.ai/mcp`

See [Connect your AI client](/mcp-server/connect) for the per-region setup in Claude, Cursor, and ChatGPT.
