SQLGen is a free, AI-powered SQL generation tool designed to remove the friction between an idea and a working database query. Whether you need a quick SELECT statement or a complex multi-table JOIN with window functions, SQLGen translates your plain-English description into clean, production-ready SQL in seconds — no manual syntax lookup required.
The tool supports more than a dozen database engines including PostgreSQL, MySQL, SQLite, SQL Server, BigQuery, Snowflake, ClickHouse, MongoDB, and more. You can optionally paste in your own CREATE TABLE definitions or describe your schema so the AI generates queries that match your exact structure.
SQLGen is built for everyone who works with data — backend engineers who want to move faster, data analysts who know what they want but not always the syntax, product managers exploring datasets, and students learning SQL for the first time. Authenticated users get unlimited daily queries and a personal saved query history, while guests can try the tool instantly with no sign-up required.
SQLGen is independently developed and maintained by a small team of engineers passionate about developer tooling and making data more accessible. We are committed to keeping the core product free and to building thoughtfully in the open. Have feedback or a feature request? We'd love to hear from you.
