Why Choose Fixie?
Poor SQL is a respected open-source tool built on the Poor Man's T-SQL Formatter library. It's focused primarily on T-SQL (Microsoft SQL Server) and offers excellent offline support — once you load the page, it works without an internet connection. If you work exclusively with T-SQL and value open-source software, Poor SQL is a solid choice.
Fixie's SQL Formatter & Explainer offers broader SQL dialect support (PostgreSQL, MySQL, SQLite) and additional analysis features beyond formatting. The query explainer provides plain-English descriptions of what your SQL does, the visualizer shows query structure as a tree diagram, and the minifier compresses queries for production use. Fixie also includes real-time syntax validation with error highlighting.
Both tools share the same privacy-first philosophy — all processing happens in your browser, so your SQL code never leaves your device. Poor SQL has the advantage of being open-source and working offline. Fixie provides a more comprehensive feature set with multi-dialect support and query analysis tools. Both are completely free with no ads or tracking. Choose Poor SQL if you need offline T-SQL formatting, or Fixie if you want additional analysis features and support for PostgreSQL, MySQL, or SQLite.
