Key differences
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
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
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
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
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?
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.
