Content Summary
A developer created an automated workflow using n8n, Wappalyzer API, and Claude AI to scan websites and identify their tech stacks. The system automatically organizes data into categories and exports to Google Sheets, saving 20+ hours weekly previously spent on manual research. While some commenters noted existing alternatives like BuiltWith.com and Wappalyzer extensions, others appreciated the automation approach and integration with modern tools.
Opinion Analysis
Mainstream opinion recognizes the value in automating repetitive research tasks, with many users appreciating the time-saving aspect. However, significant debate exists regarding:
- Novelty: Multiple commenters point out this functionality has existed for 15+ years (BuiltWith.com, Wappalyzer extension)
- AI Necessity: Skepticism about using Claude for JSON parsing when structured data exists
- Accuracy Concerns: Potential AI hallucinations affecting data reliability
- Marketing Motives: Accusations of disguised advertising for Wappalyzer/n8n Supporters argue modern accessibility and workflow integration justify the approach, while critics view it as redundant.
