Quick Decision Guide

Which SQL generator should you use?

I have a business question, not a query

Start with text to SQL to turn plain English into a first working draft.

My SQL throws an error

Use SQL Validator to identify syntax issues, explain them, and create a corrected version.

The query works but is hard to read

Use SQL Formatter to clean structure, indentation, and line breaks before review or handoff.

The query is too slow or too expensive

Use SQL Optimizer to improve runtime, reduce scan cost, and review index-aware suggestions.

I need to understand someone else's SQL

Use SQL Explainer for inline comments, summaries, and clause-by-clause explanations.

I need the same query in another dialect

Use SQL Converter when moving SQL between PostgreSQL, MySQL, SQL Server, Snowflake, BigQuery, and more.
