# Snowplow documentation
> Docs for Snowplow CDI, which collects, validates, and models behavioral data in your cloud, and Signals, which serves real-time attributes to apps and agents.

Snowplow Customer Data Infrastructure (CDI) collects behavioral data from your websites, apps, and servers, validates every event against your schemas, and delivers it to your own warehouse, lake, or stream. Signals uses the same events to calculate user attributes in real time, and serves them to your applications and AI agents.

Using a coding agent? [Connect it to the docs](/docs/ai/#connect-your-coding-agent).

## Choose a product

Use CDI to collect behavioral data and analyze it in your warehouse. Use Signals to act on that behavior in real time, in your app or AI agent.

Snowplow CDI

### [Behavioral data in your warehouse](/docs/cdi/)

Track events from any platform, validate them against your schemas, load them into your warehouse, and model them into tables for analysis.

```js
import { newTracker, trackPageView } from '@snowplow/browser-tracker';
newTracker('sp', '{{collector_url}}', { appId: 'my-app' });
trackPageView();
```

Signals

### [Real-time user attributes for apps and agents](/docs/signals/introduction/)

Calculate user attributes as events arrive, and read them from your app or agent with one API call.

```ts
import { Signals } from '@snowplow/signals-node';
const signals = new Signals({ baseUrl, apiKey, apiKeyId, organizationId });
const attributes = await signals.getServiceAttributes({ name: 'my_service', attribute_key: 'domain_userid', identifier });
```
