PerformanceStudio vs initrunner
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.; initrunner: InitRunner lets you define an agent in one YAML file, chat with it, run it autonomously, and deploy it as a daemon triggered by cron, file changes, webhooks, or Telegram messages. It supports multiple execution modes, built-in memory, cost controls, multi-agent orchestration, and security features. Built on PydanticAI.

TL;DR
Choose PerformanceStudio if…Analyze slow queries by loading .sqlplan files or capturing plans from live SQL Server instances
Choose initrunner if…Automated code review: set up a daemon that reviews pull requests or file changes.
