The SQL Server First Responder Kit (FRK) is one of the most widely used open‑source diagnostic toolkits in the SQL Server community. It includes stored procedures like sp_Blitz, sp_BlitzCache, sp_BlitzIndex, sp_BlitzFirst, and sp_BlitzLock, each designed to analyze a specific part of SQL Server performance.
AI SQL Tuner, on the other hand, is a modern, AI‑powered performance tuning platform that automates server health checks, index analysis, code review, deadlock analysis, and prioritization — all in a single workflow.
This comparison helps you understand where each tool excels and which one fits your environment.

Feature Comparison: AI SQL Tuner vs. First Responder Kit
| Category | AI SQL Tuner | First Responder Kit |
|---|---|---|
| Core Capabilities |
Server health analysis Index analysis (missing, unused, overlapping) Query code review Deadlock analysis AI‑powered prioritization and explanations |
sp_Blitz — overall health check sp_BlitzCache — plan cache analysis sp_BlitzIndex — index analysis sp_BlitzFirst — real‑time performance diagnostics sp_BlitzLock — deadlock analysis |
| Scope of Tuning | Full‑stack tuning: server, queries, indexes, deadlocks, security | Diagnostic toolkit; results require manual interpretation |
| Actionability | Provides fixes, impact estimates, and rollback paths | Provides findings; user must determine fixes |
| Automation | Automated analysis and AI‑generated recommendations | Manual execution of stored procedures |
| Cost |
Free tier available Standard: $100/year Pro: $200/year Corporate: $500/year |
Free (open source) |
| Deadlock Resolution | Yes — AI‑assisted deadlock graph analysis | Yes — via sp_BlitzLock |
| Code Review | Yes — detects anti‑patterns, parameter sniffing, etc. | No dedicated code review tool |
| Server Health | Yes — configuration, waits, security | Yes — via sp_Blitz health check |
| Index Tuning Depth | Advanced: missing, unused, overlapping indexes with DDL | Strong analysis via sp_BlitzIndex; no automated DDL generation |
| AI Integration | Yes — GPT‑powered reasoning | No |
Summary: Which Should You Use?
Choose AI SQL Tuner if you want:
- Automated, AI‑powered analysis
- A single tool that covers server health, indexes, queries, and deadlocks
- Actionable fixes with explanations
- Faster triage and reduced manual effort
Choose First Responder Kit if you want:
- A free, open‑source toolkit
- Deep, script‑level visibility into SQL Server internals
- Community‑driven diagnostics
- A manual, script‑based workflow
Both tools can complement each other — FRK is excellent for deep dives, while AI SQL Tuner accelerates day‑to‑day performance tuning.
