What sql-tools is
sql-tools is a free browser-based toolkit for engineers working with Snowflake, BigQuery, Databricks, PostgreSQL, MySQL, and SQL Server. Its formatter supports those six SQL dialects, with controls for indentation and keyword case. The site also offers SQL escaping and unescaping, minification, and an AI-powered dialect translator. Translation requests go through OpenRouter and are limited to 30 per IP per hour; cached repeat requests do not count toward the limit. Identical translator queries are cached for 24 hours using a SHA-256 hash of normalized input, and the site says it does not keep query logs. The maker says tools other than the AI translator run in the browser without accounts, uploads, or query tracking. Its privacy policy advises against entering confidential or proprietary information unless comfortable with its processing, and notes that reasonable safeguards cannot guarantee complete security. Translations for complex stored procedures and warehouse-specific UDFs may be partial, so output should be reviewed and tested before production use. An ERD generator and AI query optimizer are listed as coming soon.
