# OpenPanel

> Privacy-friendly web analytics: visitors, sessions, page views, live visitors, referrers, and more.

# OpenPanel

OpenPanel provides web analytics data including visitor counts, session metrics, page views, bounce rate, average session duration, live visitor count, top pages, and referrers.

## What it powers

* **Analytics widget** -- Live visitors, sessions, page views, bounce rate
* **KPI Strip** -- Live visitor count cell
* **Detail panel** -- Falls back to analytics data when other services are unavailable

## Getting your API keys

<Steps>
  <Step title="Sign in to OpenPanel">
    Go to [dashboard.openpanel.dev](https://dashboard.openpanel.dev/) and sign in.
  </Step>

  <Step title="Navigate to your project settings">
    Select your project, then go to **Settings** > **API Keys** (or **Clients**).
  </Step>

  <Step title="Copy Client ID and Secret">
    You need a **Client ID** and **Client Secret** pair. If you track multiple sites, you use one shared root client for the Radarboard API, and per-site clients for the MCP servers.
  </Step>
</Steps>

## Environment variables

```bash .env.local theme={null}
# Shared root client (used by the radarboard API)
OPENPANEL_CLIENT_ID=your-client-id
OPENPANEL_CLIENT_SECRET=your-client-secret
```

<Tip>
  If you also want to use the OpenPanel MCP servers for AI agents, you'll need per-site credentials. See [OpenPanel MCP](/mcp-servers/openpanel).
