It's great to see your interest in web scraping and data consolidation! Let's break down your questions one by one:
Generic Web Scraper for Raspberry Pi 4b – While there isn't a built-in, one-size-fits-all web scraper for Raspberry Pi, you can use existing Python-based frameworks like Scrapy, which is efficient and works well on Pi. Alternatively, WebHarvy and Octoparse are user-friendly, no-code scraping solutions that might fit your needs.
Versatility of Web Scrapers – Web scrapers can be generic or highly specialized. If sites have similar structures, a single scraper with minor adjustments can work across multiple platforms. However, if each site has different layouts and protections (e.g., CAPTCHA or dynamic content), customization is often necessary.
Legal Considerations – Scraping publicly available data is a gray area. While robots.txt files provide guidelines on what can be scraped, some sites explicitly forbid it in their terms of service. Be cautious and ensure compliance, especially if you're dealing with copyrighted or sensitive information.
Web Crawler vs. Web Scraper – A web crawler systematically browses the web and indexes pages (like search engines), whereas a web scraper extracts specific data from targeted pages. Crawlers discover and catalog content, while scrapers collect structured information for analysis.
Best Tools for Your Needs – Your current stack (Python, BeautifulSoup, and MySQL) is a solid choice for basic scraping. However, Scrapy provides more power and automation. If you're looking for a simpler, no-code solution, consider using ParseHub or Diffbot.
