What is n8n Workflow Analyzer?

n8n Workflow Analyzer is a free, privacy-focused tool designed to help n8n users identify security vulnerabilities, performance bottlenecks, and reliability issues in their automation workflows. Unlike other tools, all analysis is performed directly in your browser - your workflow data never leaves your device.

Key Features

  • Security Audit: Detect exposed API keys, insecure webhooks, and remote code execution risks
  • Performance Analysis: Find N+1 query patterns, token bloat, and inefficient AI node usage
  • Reliability Scanning: Catch fragile loops, silent failures, and missing error handlers
  • AI-Powered Deep Scan: Get advanced semantic analysis using Google Gemini AI
  • 100% Privacy: All local analysis happens in your browser with zero data transfer

Common Issues Detected

  • Hardcoded credentials and API keys in workflow nodes
  • Public webhooks without authentication
  • Execute Command nodes with unsanitized inputs
  • Loops without error handling that can crash entire workflows
  • Merge nodes that block forever when one branch fails
  • Polling intervals that are too aggressive
  • Missing error workflow configuration
  • Workflows exceeding recommended node counts

How to Use

  1. Export your n8n workflow as JSON from the n8n editor
  2. Drag and drop the JSON file onto this page or click to browse
  3. Review the instant local analysis results
  4. Optionally run AI-powered deep scan for advanced insights
  5. Fix the identified issues in your n8n workflow
