Sqlsure - Deterministic semantic checks for AI-generated SQL

Show HN: Sqlsure – deterministic semantic checks for AI-generated SQL

Sqlsure is a semantic inspector that catches critical SQL errors like double-counting, additivity violations, and wrong join keys before queries run. Unlike standard linters or LLMs, it uses deterministic rules derived from your existing dbt tests or database schema to validate AI-generated SQL in milliseconds. By integrating into CI pipelines, MCP servers, or as a library, Sqlsure ensures data accuracy and prevents silent revenue miscalculations, offering machine-actionable fixes for instant self-repair of AI agents.

"A query can be perfectly valid, run without error, and return a number that's silently wrong — sqlsure does — deterministically, in 0.1 ms, before the query runs."
