Greysight (Tool)
Greysight is a new open-source tool for Snowflake that monitors warehouse, AI, and storage costs without ever accessing underlying user data.
What: The tool uses read-only access to ACCOUNT_USAGE and ORGANIZATION_USAGE metadata schemas, ensuring credentials are encrypted in Supabase Vault and no data is persisted beyond volatile memory.
Why it matters: As organizations grapple with unpredictable Snowflake billing, especially regarding AI features like Cortex, the market is moving toward local-first, privacy-conscious cost auditing tools.
Takeaway: If you are struggling with Snowflake budget transparency, connect a read-only role to the Greysight self-hosted container to identify inefficient warehouse utilization.
