Is Scrapy Splash faster than Selenium
Scrapy is the one with the best speed since it's asynchronous, built especially for web scraping, and written in Python. However, Beautiful soup and Selenium are inefficient when scraping large amounts of data.
Why scrapy is fast
Scrapy is asynchronous, it executes multiple requests simultaneously. Even if a request fails or any errors happen the incoming requests aren't affected. This improves the overall speed efficiency of the process.
What is splash scrapy
Scrapy Splash is a lightweight browser with an HTTP API; it's used to scrape websites that render data with JavaScript or AJAX calls.

What are the disadvantages of Scrapy
The first disadvantage is its complexity. Scrapy is known for its steep learning curve. If you're new to web scraping, you'd probably want to go for a beginner-friendly alternative, such as Beautiful Soup. The other disadvantage is that Scrapy cannot scrape dynamically loaded content on its own.
What are the limitations of Scrapy
Since it is asynchronous, Scrapy can make multiple requests parallelly. This increases efficiency, which makes Scrapy memory and CPU efficient compared to conventional tools like Selenium, python-requests, JAVA JSoup, or rest-assured. One of the limitations of Scrapy is that it cannot process JavaScript.
Does Scrapy use Selenium
Like other headless browsers you can configure Scrapy Selenium to do certain actions before returning the HTML response to your spider. Splash can: Wait for page elements to load. Scroll the page.
Is Scrapy good for web scraping
Scrapy is a wonderful open source Python web scraping framework. It handles the most common use cases when doing web scraping at scale: Multithreading. Crawling (going from link to link)
Is Scrapy better than BeautifulSoup
Generally, we recommend sticking with BeautifulSoup for smaller or domain-specific scrapers and using Scrapy for medium to big web scraping projects that need more speed and control over the whole scraping process.
Should I use Scrapy or Beautifulsoup
Scrapy is a more robust, feature-complete, more extensible, and more maintained web scraping tool. Scrapy allows you to crawl, extract, and store a full website. BeautilfulSoup on the other end only allows you to parse HTML and extract the information you're looking for.
Why use Selenium with Scrapy
Selenium cannot handle large data, but Scrapy can handle large data with ease. Also, Selenium is much slower when compared to Scrapy. So, the smart choice would be to use Selenium with Scrapy to scrape dynamic webpages containing large data, consuming less time.

Should I use Selenium or Scrapy
If the data is included in html source code, both frameworks can work fine and you can choose one as you like. But in some cases the data show up after many ajax/pjax requests, the workflow make it hard to use Scrapy to extract the data. If you are faced with this situation, I recommend you to use Selenium instead.
Is there a better alternative to Selenium
Cucumber is another well-known Selenium alternative and functions as an automation tool for behavior-driven development (BDD). It was originally written in the Ruby programming language but now supports Java and JavaScript.
Is Selenium getting outdated
Selenium still has its place because there could be times when Cypress may not be suitable for your automation needs. We believe that Cypress is a great tool and is worth exploring if you have not experimented with it yet. You will see how easy it is to get started writing tests and the benefit of their Test Runner.
Is Selenium still popular
Selenium is among the leading tools for end-to-end testing. It is an open source automation framework that's used to test many common browsers and cloud platforms.

Does Selenium have future
Selenium Jobs in 2023:
2023 already brings a fortune as it is expected to have 27,453 new openings for software testing jobs across India, as per Shine.com. According to Naukri, around 5,297 Selenium job openings are waiting to test our skills and employ us.
Is Selenium in demand in 2023
Here is a list of 10 automation testing tools that are in demand in 2023. A popular open-source web automation tool is Selenium, which can automate several operating systems, including Windows, Mac OS X, and Linux, as well as multiple browsers, including Firefox, Chrome, Internet Explorer, and Headless Browsers.
