Browser-based tools for day-to-day database work

These utilities support query review and troubleshooting across SQL Server, Azure SQL, Kusto, PostgreSQL, and MySQL workflows. Query formatting, linting, and plan visualization run locally in your browser, so pasted query text is not sent to the application server.

For version and patch research, use the SQL Server and SSMS release tracker. For practical examples and troubleshooting notes, browse the Microsoft Data Platform blog.
