Our verdict on SQLCheck

SQLCheck is an open-source command-line tool for developers and database teams reviewing SQL quality, database design, and potential performance problems. It analyzes SQL files and identifies logical database design, physical database design, query, and application-development anti-patterns. The project supports Microsoft SQL Server, MySQL, Oracle, PostgreSQL, and SQLite3, with downloadable packages for Windows, macOS, and Linux. Its focus is auditing and diagnosis rather than formatting or query rewriting.

Its strongest differentiator is the breadth of anti-pattern coverage within a focused command-line workflow. Checks can be filtered by risk level, helping teams narrow reviews to issues with the desired severity. Colorized output can improve terminal readability, while verbose output provides more detail for investigation. That combination is suited to database reviews where the priority is understanding design and query problems across multiple SQL dialects, rather than applying a standardized style automatically.

SQLCheck is a practical fit for teams comfortable reviewing SQL from the command line and incorporating findings into their own development process. It should not be the first choice for teams seeking automatic fixes, editor-integrated feedback, configuration-file support, or built-in CI features. It also is not positioned as a hosted service or a broader database governance platform. Choose SQLCheck when anti-pattern detection across several database systems is the main requirement; choose an alternative when formatting, autofix, or integrated developer tooling is central to the workflow.

How long have you used it?

I've used SQLCheck myself and this is my honest opinion — nobody paid or asked me to write it.
