Show HN: Strata – an expressive semantic layer that can say no to your LLM

Strata is a semantic layer tool that allows users to build data models using AI coding agents (like Claude) rather than manual coding, with a free local setup requiring only Docker and basic dependencies. The platform runs entirely on your machine with no configuration needed, supports multiple data warehouses (Snowflake, Databricks, PostgreSQL, etc.), and includes a CLI for project management and deployment. Users can start exploring with a pre-loaded sample retail model within 15 minutes of installation.
