Why you should use it: As an open source tool, Scrapy is
completely free. It is battle tested, and has been one of the most popular
Python libraries for years, and it’s probably the best python web scraping tool
for new applications. It is well documented and there are many tutorials on how
to get started. In addition, deploying the crawlers is very simple and

Who is this for: Enterprises who who have specific data crawling and screen scraping needs, particularly those who scrape websites that often change their HTML structure.
Why you should use it: Diffbot is different from most page
scraping tools out there in that it uses computer vision (instead of html
parsing) to identify relevant information on a page. This means that even if

as the page looks the same visually. This is an incredible feature for long
running mission critical web scraping jobs. While they may be a bit pricy (the
cheapest plan is $299/month), they do a great job offering a premium service
that may make it worth it for large customers.
Who is this for: NodeJS developers who want a straightforward
way to parse HTML. Those familiar with jQuery will immediately appreciate the

NodeJS developers who want very granular control over their scraping activity.
Why you should use it: As an open source tool, Puppeteer is
completely free. It is well supported and actively being developed and backed
by the Google Chrome team itself. It is quickly replacing Selenium and
PhantomJS as the default headless browser automation tool. It has a well
thought out API, and automatically installs a compatible Chromium binary as
part of its setup process, meaning you don’t have to keep track of browser
versions yourself. While it’s much more than just a web crawling library, it’s
information, it handles scripts, stylesheets, and fonts just like a real
browser. Note that while it is a great solution for sites that require
for sites where a full blown browser is not necessary is probably not a great
idea. Most times a simple GET request should do the trick!
