OwlEye vs Umami
Both take a cookie-free approach. Umami offers managed cloud and self-hosted operation; OwlEye is a managed hosted product. A clear architectural difference is OwlEye's ClickHouse event pipeline versus Umami's PostgreSQL application stack.

Migration notes
- Export the Umami events and website identifiers you need before changing trackers; the two products use different schemas.
