0sql

0sql: Semantic layer as a service that turns structured specs into one correct SQL statement with row-level security.

0sql acts as a semantic layer as a service for applications and AI agents. Your code or agent sends a structured query spec containing measures, dimensions, filters, and cohorts, and 0sql returns one correct SQL statement for your warehouse with row-level security compiled in. It never connects to your warehouse, ensuring your data never leaves your network. The semantic model is defined as YAML in git and deployed per branch. It supports thirteen dialects including Postgres, Snowflake, BigQuery, Databricks, and Redshift, making it suitable for AI agents, embedded analytics, and platform teams.
