SQL Linters and Formatters
Alternatives to SQLCheck
SQLCheck gives a free way to inspect SQL files for anti-patterns that may slow queries. Its checks span logical and physical database design, queries, and application development, while risk filters let you review everything or concentrate on medium/high- and high-risk patterns. It targets major SQL dialects and runs from a command line on Linux, macOS, and Windows, with color and verbose output.

Choosing instead of SQLCheck
That focus also defines the trade-off. SQLCheck has no automatic fixes, editor extension, configuration file, graphical interface, hosted service, API, or mobile app, and its documented workflow analyzes files. An alternative may be preferable for formatting, migration-risk checks, editor feedback, pull-request automation, broader dialect-specific linting, or changing code automatically. Compare whether you need detection or reformatting, which SQL dialects matter, where the tool should run, and whether integration, configuration, or fixes are essential to your workflow.
