# walkerOS vs. Segment

[Segment](https://segment.com/) (owned by Twilio) is a Customer Data Platform (CDP) that collects, unifies, and routes customer data. It's one of the most well-known names in the space. Here's how it compares to walkerOS.

* You want composable, component-level tagging

## Key differences[​](#key-differences "Direct link to Key differences")

### Scope[​](#scope "Direct link to Scope")

**Segment:** A full Customer Data Platform. Beyond event collection, it offers identity resolution, audience building, journey orchestration, and reverse ETL. It's designed for marketing and data teams who need unified customer profiles.

**walkerOS:** Focused event collection and routing infrastructure. Collect events from sources, process them, send them to destinations. It does one thing well without the CDP overhead.

### Cost[​](#cost "Direct link to Cost")

**Segment:** Free tier limited to 1,000 MTUs. Team plan starts around $120/month. Pricing scales with monthly tracked users (MTUs). Enterprise customers often negotiate 70-80% discounts on list prices, but costs can grow quickly at scale.

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

### Integrations[​](#integrations "Direct link to Integrations")

**Segment:** 700+ pre-built integrations. Connect to almost any marketing, analytics, or data tool without writing code. Great if your stack is covered.

**walkerOS:** Fewer pre-built destinations, but full flexibility to build custom integrations. Send data anywhere via destinations you control. Better for teams with specific requirements or internal systems.

### Data ownership[​](#data-ownership "Direct link to Data ownership")

**Segment:** Data flows through Segment's infrastructure. While they offer privacy features and compliance certifications, you're trusting a third party with your customer data.

**walkerOS:** Self-hosted by default. Your data never leaves your infrastructure unless you explicitly send it somewhere. Full control over where data lives and how it's processed.

### Developer experience[​](#developer-experience "Direct link to Developer experience")

**Segment:** SDK-based tracking with a GUI for configuration and debugging. Good documentation, but less control over the underlying behavior.

**walkerOS:** Code-first, config-as-code approach. HTML attribute-based tagging for web. Version control your tracking setup, review in PRs, test before production.

## Can they work together?[​](#can-they-work-together "Direct link to Can they work together?")

Yes! You can use walkerOS for event collection and send data to Segment as a destination. This gives you walkerOS's composable tagging and consent handling on the frontend, while still feeding data into Segment's CDP for identity resolution and downstream integrations.
