- ✓No vendor lock-in on your customer data pipeline
- ✓Self-hosted deployment keeps PII in your own infrastructure
What you give up

- △No Unify for cross-device identity resolution
- △No Reverse ETL for syncing warehouse data back to tools
Switching Cost
Segment's lock-in is the destination graph. Your event tracking code is a thin SDK call that ports easily, but the 400+ destination connectors with managed auth, retry logic, and schema mapping take serious work to replicate. Teams sending data to 3-4 destinations can migrate in a week. Teams with 20+ destinations, Protocols enforcement, and Personas audiences should budget a month. The hidden cost is that every destination integration you rebuild also needs its own error handling and retry logic.

Building Blocks
Segment is a platform. It bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
