Who should use what?

Choose Snowplow if

• You have a dedicated data engineering team
• You need enterprise-grade data infrastructure at scale
• Your primary goal is feeding data warehouses (Snowflake, BigQuery, Databricks)
• You want 35+ pre-built trackers across platforms
• Budget allows for $800+/month or self-hosting resources

Choose walkerOS if

• You want something lightweight and quick to set up
• You're a developer or small team without dedicated data engineers
• You need destinations beyond data warehouses
• You prefer an MIT license over restricted licenses
• You want to start free and scale as needed

Key differences

Complexity and setup

Snowplow: Infrastructure built for large-scale data operations. Setup takes significant time and often dedicated data engineering resources. The open-source version needs self-hosting expertise, and the managed BDP starts at $800/month.

walkerOS: Lightweight and developer-friendly, with setup measured in hours rather than weeks. It is meant for teams that want tracking infrastructure without the complexity of an enterprise data platform.

Licensing

Snowplow: The open-source version uses the Snowplow Limited Use License Agreement (SLULA), which restricts commercial use. Full commercial use requires their enterprise offering.

walkerOS: MIT licensed. You can use it commercially, modify it, and fork it without restrictions.

Cost

Snowplow: BDP Cloud starts at $800/month. Self-hosted open-source is "free" but requires significant infrastructure and engineering investment. Enterprise tiers (Basecamp, Ascent, Summit) scale up with custom pricing.

walkerOS: The software is free and open-source, and you pay for your own infrastructure. Optional paid services include implementation support (setup fees) and SLAs for teams that want help getting started or need guaranteed support.

Focus and philosophy

Snowplow: Customer data infrastructure (CDI) for feeding data warehouses and powering analytics at scale, aimed at data teams building sophisticated data products.

walkerOS: Event collection and routing that sends data anywhere: analytics tools, data warehouses, marketing platforms, or your own APIs. It is aimed at developers who want control without that complexity.

When they overlap

Both solutions can:

• Collect behavioral event data
• Self-host on your infrastructure
• Send data to warehouses and other destinations
• Handle consent management

Where they differ is scale and complexity: Snowplow is a full data platform, and walkerOS is focused event infrastructure.

Can they work together?

Yes. You can use walkerOS for event collection and send the data to Snowplow as a destination. walkerOS then handles composable tagging and consent on the frontend, and Snowplow's data infrastructure runs on the backend.

Using the Snowplow destination

The @walkeros/web-destination-snowplow package provides full integration:

import { startFlow } from '@walkeros/collector';
import { destinationSnowplow } from '@walkeros/web-destination-snowplow';

const { elb } = await startFlow({
  destinations: {
    snowplow: {
      destination: destinationSnowplow,
      config: {
        settings: {
          collectorUrl: 'https://collector.yourdomain.com',
          appId: 'my-app',
          userId: 'user.id', // Cross-session user stitching
        },
      },
    },
  },
});

It supports:

• Full ecommerce tracking (product views, cart actions, transactions)
• Cross-session user identity via setUserId
• Anonymous tracking mode for privacy compliance
• Page context with setPageType
• Global contexts and custom schemas
• Activity tracking (page pings)
• Plugin support (NPM and URL-based)

See the Snowplow destination documentation for full configuration options.
