looking for ethical web scraping templates with built-in rate limiting

I’m starting a large-scale data collection project for market research, and I want to make sure I’m doing it the right way. My team needs to scrape product information from about 50 e-commerce sites, but we want to be respectful of their servers and follow ethical scraping practices.

I’m specifically looking for templates or pre-built configurations that include:

  • Proper rate limiting to avoid overwhelming target servers
  • Respect for robots.txt directives
  • CAPTCHA handling for sites that use them
  • User-agent rotation to distribute requests

Has anyone found good marketplace templates that already have these compliance features built in? I’d rather not reinvent the wheel if there are existing solutions that follow best practices for ethical web scraping at scale.

What templates or configurations have worked well for your large-scale scraping projects?
