Does it support all SQL dialects?
The formatter handles standard SQL and most MySQL/PostgreSQL/SQLite syntax. Dialect-specific extensions (stored procedures, DELIMITER) are left as-is.
Is my SQL sent to a server?
No. Formatting runs entirely in JavaScript in your browser. Sensitive queries never leave your machine.
