Capability matrix across the five evaluation criteria from the pillar guide. The full justification for each row is in the head-to-head comparison pages linked above.
| Criterion | Cube | Looker | dbt SL | AtScale | ThoughtSpot | Colrows |
|---|---|---|---|---|---|---|
| Graph autonomy | Hand-authored (YAML / JS) | Hand-authored (LookML) | Hand-authored (MetricFlow) | Hand-authored cubes | Worksheet / model authored | Autonomous build + drift detection |
| Dialect coverage | Limited dialect-perfect output | BI-centric, dashboard-scoped | Warehouse-scoped | Cube-output focused | Embrace-of-warehouse | 16+ engines, dialect-perfect |
| Compile-time governance | Application-level | BI-application-scoped | Warehouse-policy advisory | Cube-tier security | Worksheet-scoped | RBAC, ABAC, row/column predicates injected at compile time |
| AI-agent readiness | HTTP/SQL APIs, no proven joins | BI-agent (Looker AI), explore-scoped | Metric API, no proven joins | OLAP API | Sage AI inside ThoughtSpot | HTTP/JDBC/MCP with proven join paths and audit trail per query |
| Audit trail / reproducibility | Application-level logs | Looker activity logs | Query history | Cube-tier logs | Worksheet-history | Point-in-time reproducible (graph version + identity + proven joins + compiled SQL) |
Capability descriptions reflect each vendor's published documentation as of 2026. The head-to-head pages cite the specific docs each row is based on.
Where do Snowflake Cortex Analyst and Databricks Genie fit?
Cortex Analyst and Databricks AI/BI Genie are warehouse-native conversational analytics surfaces, not cross-estate semantic layers. They are excellent if your entire analytical surface lives inside one warehouse. They are not the right product if your AI agents need to compile across multiple sources with cross-estate governance. Read the full deep-dive on warehouse-native semantic layers.
How should you pick?
Match product to problem. If your consumers are mostly humans inside one BI tool, the BI semantic layer is fine. If you live entirely inside Snowflake or Databricks and your queries are structured-only, the warehouse-native surface is the simplest answer. If your AI strategy depends on agents that issue thousands of queries per hour across multiple sources, with regulated audit and governance, the only structurally-correct answer is a semantic execution layer. The full 2026 buyer's guide walks through each scenario, and the accuracy evidence behind the whole category - benchmarks included - is in Deterministic vs Probabilistic Text-to-SQL.
