erikdarlingdata/PerformanceStudio
Free, open-source SQL Server execution plan analyzer — cross-platform GUI + CLI with 30 analysis rules, missing index detection, SSMS extension. Built-in MCP server for AI-assisted plan review.
Performance Studio helps database administrators and developers quickly identify and fix issues with slow-running SQL Server queries. It takes SQL Server execution plans (either live from the server or as .sqlplan files) and highlights performance bottlenecks, suggests missing indexes, and explains why a query might be underperforming. This allows database professionals to optimize queries and improve application responsiveness.
109 stars.
Use this if you need to quickly diagnose and resolve performance problems in SQL Server queries without manually sifting through complex execution plans.
Not ideal if you are looking for a general-purpose SQL query editor or a tool for database design, as its primary focus is on performance analysis.
