3.9 out of 5
Scored by Alex after real useOur verdict
Select Star automatically analyzes and documents your data, tracing column-level lineage so you can see exactly where sensitive data flows and which dashboards depend on a given table. It's meant to replace the usual back-and-forth of asking colleagues where data comes from with a searchable, shared knowledge base. Its real value shows up when migrating or changing data models, flagging what might break before you touch anything, which matters more for complex warehouses than simple setups.
