Overview

RudderStack is a customer data platform (CDP) built with a developer-first and warehouse-centric approach. Established in 2019, it provides tools for collecting, transforming, and routing customer event data from various sources to a wide array of destinations, including data warehouses, analytics platforms, and marketing tools. The platform is designed for organizations that want to maintain control over their customer data within their existing cloud data warehouse infrastructure, rather than relying on a proprietary vendor database.

The system's core functionality revolves around its Event Stream, which captures customer interactions across web, mobile, and server-side applications using a range of SDKs for JavaScript, Python, Go, Java, Android, iOS, React Native, Flutter, and Unity. This collected data can then be transformed and sent to over 200 destinations. RudderStack also offers Reverse ETL capabilities, allowing users to extract modeled data from their data warehouse and send it to operational tools for activation, such as CRM systems or advertising platforms. This approach contrasts with traditional CDPs that often store customer data in their own systems before routing it, giving users more flexibility and control over their data governance and architecture.

RudderStack is particularly suited for data-driven marketing teams and developers aiming to build custom analytics stacks. Its open-source core provides transparency and allows for self-hosting options, which can be beneficial for organizations with specific security or compliance requirements. By focusing on integrating with existing data warehouses like Snowflake, Databricks, and Google BigQuery, RudderStack positions itself as an infrastructure layer for customer data, enabling real-time data activation and connecting disparate data sources to various business tools. The platform supports compliance standards such as SOC 2 Type II, GDPR, CCPA, and is HIPAA ready, addressing enterprise-level data privacy and security needs.

Getting started

To begin collecting data with RudderStack, you typically integrate one of its SDKs into your application. Here's a basic example using the RudderStack JavaScript SDK to track page views and identify users on a website:

<!DOCTYPE html>
<html>
<head>
  <title>RudderStack Getting Started</title>
  <script type="text/javascript">
    !function(){var t=window.rudderanalytics=window.rudderanalytics||[];for(var e=["load","page","track","identify","alias","group","ready","reset","getAnonymousId","setAnonymousId","getUserId","setUserId","getTraits","setTraits","on","once","off"],n=0;n<e.length;n++){var i=e[n];t[i]=function(t){return function(){var e=Array.prototype.slice.call(arguments);return t.apply(this,e)}}}(t.url="YOUR_DATAPLANE_URL",t.load("YOUR_WRITE_KEY"),t.page())}()
  </script>
</head>
<body>
  <h1>Welcome to My Website</h1>
  <button onclick="rudderanalytics.track('Button Clicked', { buttonName: 'Call to Action' })">Click Me</button>

  <script type="text/javascript">
    // Identify a user after they log in or sign up
    rudderanalytics.identify('user-123', {
      email: '[email protected]',
      name: 'John Doe',
      plan: 'premium'
    });

    // Track a specific event
    rudderanalytics.track('Product Viewed', {
      productId: 'abc-123',
      productName: 'Sample Product',
      category: 'Electronics'
    });
  </script>
</body>
</html>

In this example:

  1. Replace "YOUR_DATAPLANE_URL" with your RudderStack Data Plane URL (e.g., https://yourcompany.dataplane.rudderstack.com).
  2. Replace "YOUR_WRITE_KEY" with the actual write key from your RudderStack source.
  3. The t.page() call automatically tracks a page view when the script loads.
  4. The rudderanalytics.track() function is used to record custom events, such as a 'Button Clicked' or 'Product Viewed' event, along with associated properties.
  5. The rudderanalytics.identify() function associates subsequent events with a specific user ID and their traits.

After setting up the source, you would then configure destinations within the RudderStack dashboard to route this collected data to your desired analytics tools, data warehouses, or marketing platforms. For more detailed instructions and other SDKs, refer to the RudderStack documentation.
