Performance Benchmark
Scraping 1000 pages:
- Python (Scrapy): 45 seconds
- Node.js (Puppeteer): 38 seconds
- Python (Requests + BS4): 8 minutes
- Node.js (Axios + Cheerio): 6 minutes
Choose Python If:
- ✅ You're new to scraping
- ✅ Need extensive data processing
- ✅ Want the best library ecosystem
- ✅ Building ML/AI pipelines
- ✅ Team knows Python
Choose Node.js If:
- ✅ Performance is critical
- ✅ Your stack is JavaScript
- ✅ Need real-time scraping
- ✅ Heavy browser automation
- ✅ Team knows JavaScript
Verdict
Python wins for most use cases due to superior libraries, easier learning curve, and better data processing. Choose Node.js only if you need maximum performance or your team is JavaScript-focused.
