How to Crawl the Web with Scrapy
Rtila [1]
Created by an indy/solo developer-on-fire cranking out user-requested features quite quickly... check the releases page [2]
I have used (or at lelast trialled) the vast majority acraping tech and written hundreds of scrapers since my first VB5 controlling IE and dumping to SQLserver in the 90's and then moving to various php and python libs/frameworks and a handful of windows apps like ubot and imacros (both of which were useful to me at some point but I never use those nowadays)
A recent release of Rtila allows creating standalone bots you can run using it's built-in local Node.js server (which also has it's own locally hosted server API you can program anything else against using any language you like)

How do I scrape external web pages and then insert them as records into KB table?
You could do the scraping yourself by hosting your own ServiceNow MID Server, making a bespoke scraping script on top of an existing library (example: got-scraping), then calling the scraper script via IntegrationHub & a Script Step)

How to Crawl the Web with Scrapy
While I agree that Scrapy is a great tool for beginner tutorials and easy entry into scraping, it's becoming difficult to use it in real world scenarios because almost all the large players now employ some anti-bot or anti-scraping protection.
A great example above all is Cloudflare. You simply can't convince Cloudflare you're a human with Scrapy alone. Scrapy has only experimental support of HTTP2 and does not support proxies over HTTP2 (https://github.com/scrapy/scrapy/issues/5213). Yet, all browsers use HTTP2 now, which means all normal users use HTTP2... You get the point.
What we use now is Got Scraping (https://github.com/apify/got-scraping). It's a special purpose extension of Got (HTTP client with 18 mil weekly downloads) that masks its HTTP communication as if it was coming from a real browser. Of course, this will not get you as far as Puppeteer or Playwright (headless browsers), but it improved our scraping tremendously. If you need a full crawling library, see the Apify SDK (https://sdk.apify.com) which uses Got Scraping under the hood.
