How it compares

SQLFormat.org is the most common result but ad-supported. IDE-based formatters (DataGrip, pgAdmin) are more integrated but require install. Freesqlformatter is ad-free browser-based and supports multiple dialects.

Privacy

SQL stays in your browser — important when formatting queries that contain sensitive schema names or business logic.
