PerformanceStudio

Active·★ 245·MIT·Updated 2026-10-21

Performance Studio is a cross-platform SQL Server execution plan analyzer that parses .sqlplan XML, identifies performance problems, suggests missing indexes, and provides actionable warnings via CLI or desktop GUI. It includes a built-in MCP server for AI-assisted analysis, supports live plan capture from SQL Server, and offers features like plan comparison, Query Store integration, and SSMS extension.

PerformanceStudio sits in the Dev Tooling category, so it is usually better judged by workflow fit, deployment style, and team needs than by isolated features alone. Based on the available metadata, it leans most clearly toward Graphical plan tree with operator icons, cost percentages, row counts, and warning badges. A representative use case is Analyze slow queries by loading .sqlplan files or capturing plans from live SQL Server instances. The listed license is MIT. GitHub stars are currently 245. Relevant tags include avalonia, cli.

This write-up is based on the project's README and public repository data. We have not hand-tested the tool.
