It supports optional AI features for natural language querying and is available as a web application, desktop app, or terminal CLI.; PerformanceStudio: 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.
