## What the models said for it

- "Unity Catalog, Snowflake Horizon and AWS Glue govern their own platform well and see nothing outside it." (Muse Glimmer 30B, Data catalogs)
- "Built-in governance, data quality, and metadata management features within the Snowflake ecosystem." (Gemini 3.5 Flash, Data catalogs)
- "Great for governance *within* that specific ecosystem, but limited if you need cross-tool lineage" (Gemini 3.5 Flash, Data catalogs)
- "If 85% of your data lives in Snowflake, Snowflake Horizon is the obvious starting point." (Claude Haiku 4.5, Data catalogs)

## And against it

- "can enforce controls effectively within their ecosystems, but relying on one as the enterprise-wide system of record can create fragmented metadata" (Perplexity Sonar, Data catalogs)
- "Convenient if you're all-in on one platform, but limited if you have multi-cloud or diverse sources." (Grok 4.20, Data catalogs)
- "create governance fragmentation if your organization operates across multiple clouds" (Kimi K2, Data catalogs)
- "often too narrow for comprehensive data governance outside their native platforms" (Mistral Small, Data catalogs)
