Scrapy VS splash

BeautifulSoup4 Scrapy

While there is no specific library for SERP, there are some web scraping libraries that can do the Google Search Page Ranking. One of them which is quite famous is Scrapy - It is a fast high-level web crawling and web scraping framework, used to crawl websites and extract structured data from their pages. It offers rich developer community support and has been used by more than 50+ projects.

If you're looking for a turn-key solution, I'd have to dig a little. I generally write a scraper in python that dumps into a database or flat file (depending on number of records I'm hunting).

Scraping is a separate subject, but once you write one you can generally reuse relevant portions for many others. If you can get adept at a scraping framework like Scrapy you can do it fairly quickly, but there aren't many tools that work out of the box for every site you'll encounter.

Once you've written the spider, it's generally able to be rerun for updates unless the site code is dramatically altered. It really comes down to how brittle the spider is coded (i.e. hunting for specific heading sizes or fonts or something) instead of grabbing the underlying JSON/XHR that doesn't usually change frequently.

Scrapy capitalizes headers for request

Scrapy is a web scraping toolkit

I know this might not be a good answer, as it's not .NET, but we use https://scrapy.org/ (Python).

As for Splash, its main benefits are being smaller (as it uses QtWebkit instead of a full-blown real-world browser; this is also sometimes a drawback) and being better integrated in the Scrapy flow (as working with it means sending HTTP requests, not making synchronous API calls to a library like with Selenium). It's also deployed as a single docker image with an HTTP interface. For scaling see e.g. https://github.com/scrapinghub/splash/blob/master/splash/examples/splash-haproxy.conf

Splash is a javascript rendering service. I don't have much idea what this service actually is. All I know is the service is one of many tools that could help me scrapping sites that needs javascript to run and enabled. And Splash could work well along with Scrapy, the web scrapping framework that I currently learn about. And as always, If this service can be done installed using Docker then I would give a try the docker way.
