MotherDuck
Depot pick when the agent needs SQL warehouse context (analytics, DuckLake/Iceberg, shared Guides). Snowflake Cortex / Databricks Mosaic when the lakehouse is already the system of record. Strengths: DuckDB-shaped warehouse with first-class agent Guides/MCP/Flights; Honest Lite free tier + per-second compute; Dual exec
Strengths
- DuckDB-shaped warehouse with first-class agent Guides/MCP/Flights
- Honest Lite free tier + per-second compute
- Dual execution (local DuckDB + cloud) cuts scan cost
Weaknesses
- Single-region orgs
- Not a vector DB — VSS/extensions only
- Business $250 base can dwarf tiny agent apps (use Lite)
Snowflake Cortex
Use when Snowflake already holds the data. Don't drag agent backends into Snowflake just for Cortex. Strengths: SQL-native AI on governed data; Enterprise residency/RBAC; No separate vector infra for many RAG patterns.
Strengths
- SQL-native AI on governed data
- Enterprise residency/RBAC
- No separate vector infra for many RAG patterns
Weaknesses
- Not agent-tooling native
- Credit math opaque
- Lock-in to Snowflake warehouse economics
