The present trends in web scraping tools

Recently I got a question from one of the blog readers. After I replied to it, I decided to share it with a wider audience.
Question:

Hi,

I found your scraping.pro site and found it very helpful, then realized the web scraper solutions rating was from 2014.  What is the best solution for today?   I have lots of sites I need to scrape, mainly search then drill-down sites.   I would like to be able to schedule the scraping to run on a daily basis.  Is there a direction you could point me?  I’m a seasoned developer by trade but am seeing all these point and click solutions (e.g. import.io) and am wondering if I should stick with Node.JS or .NET or if I should investigate some of these GUI scrapers of today.

A revolutionary web scraping software to boost your business

octoparse-web-scraping-templatesIf you were an Amazon seller, would you want to know the listing price of a product of all competitors? Since you don’t have direct access to the Amazon database, you are out of luck and have to browse and click through every listing in order to construct a table of sellers and prices. A web scraping tool comes in handy. It automatically downloads your desired information such as product name, seller’s name, price, etc. However, web scraping that requires coding skill can be painful for professionals in IT, SEO, marketing, e-commerce, real estate, hospitality, etc.

It seems beyond one’s job description if he/she needs to learn how to code in order to obtain certain useful data from the web. For example, I have a friend who graduated in Mass Communication and works as a content marketer. She wants to scrape some data from the web, so she decided to learn Python herself. It took her two weeks to come up with a page of messy codes. Not only did she waste time on learning Python, but she also lost the time she could have used for doing her real work. more…

JavaScript rendering library for scraping javascript sites

logo-js-rendering-libraryCan you imagine how many scraping instruments are at our service? Though it has a long history, scraping has at last become a multi-lingual and simple approach. Unfortunately, there is a list of non-trivial tasks which can’t be resolved in a snap.

One of these tasks is scraping javascript sites, those that output data using JavaScript. Facing this task, classic scrapers (not all of them though) ignore JS-data and continue their own life-cycle.
