The ever-growing demand for big data is driving more and more people to dive into the ocean of data.

Web crawling plays an important role in crawling the web pages that are ready to be indexed. Nowadays, there are three major ways for people to crawl web data:

    • Using public APIs provided by the websites
    • Writing a web crawler program
    • Using automated web crawler tools

With my expertise in web scraping, I will discuss four free online web crawling (web scraping, data extraction, data scraping) tools that are friendly to beginners.


What is a free online web crawling tool used for?

  • A free online web crawling tool is designed to scrape or crawl data from websites.

One good thing that comes with a free online web crawling tool is that users are not required to process any coding skills. That said, it supposes to be user-friendly and easy to get hands-on. 

  • A free online web crawler helps people gather information in a multitude for later access.

A powerful free online web crawler should be able to export collected data into a spreadsheet or database and save them in the cloud. As a result, extracted data can be added to an existing database through an API. You can choose a free online web crawler tool based on your needs.
