1. Selenium

Selenium is a browser automation tool that can perform a wide range of tasks on autopilot. Mastering Selenium will definitely help you understand how websites work. With it, you can simulate a person visiting a web page using a regular browser. Thus, you can obtain accurate data about what a person sees on the page, as is. It is often used to emulate AJAX calls when scraping. Thanks to its powerful automation features, Selenium can assist you not only in website scraping but also in testing websites and automating any labor-intensive internet-related activity. In short, mastering Selenium can make you a professional in web scraping.

2. Boilerpipe

If you need to extract clean text along with relevant headlines, Boilerpipe is an excellent option. BoilerPipe is a Java library created solely for extracting data from web pages, both structured and unstructured. It can intelligently remove unnecessary HTML tags and other noise present on pages. The highlight of Boilerpipe is that it can extract relevant content in milliseconds with minimal user intervention. The accuracy is impressively high, making it one of the simplest tools for web scraping. Getting familiar with this tool can instantly improve your scraping skills.

3. Nutch

Nutch is called the gold standard of website scraping technologies. It is an open-source web scraping program that can collect and extract data from web pages in lightning speed. Nutch can be used to gather, extract, and store data after programming it to specific requirements. Behind the scenes, the program hides a sophisticated and powerful crawling algorithm, making it one of the best tools for searching the internet. To perform scraping, the web page to be viewed and data extracted must be manually encoded in Nutch. Once configured, it will scan the pages in the list and save the necessary data to the server. You can learn a few simple commands used for scraping with Nutch to make the work easier. Nutch is a very useful tool when it comes to scraping, and it should be on your list if you plan to learn website scraping.

4. Watir

Watir (pronounced "water") is a family of open-source Ruby libraries that can be used for browser automation. It is simple to use and flexible. It can interact with the browser just as a human does. Watir can perform functions such as clicking links, filling forms, pressing buttons, and literally everything a human does on a web page. Thanks to the good Ruby language, Watir is easy to use and customize. Like any other programming language, Ruby gives you the ability to read data files, export XML, connect to databases, and write spreadsheets.

5. Celerity

Celerity is a JRuby wrapper built around HtmlUnit – a headless Java browser with JavaScript support. It has an easy-to-use API that can be used to programmatically navigate web applications. It is impressively fast as it doesn't require lengthy GUI rendering or unnecessary downloads. Being scalable and non-intrusive, it can silently run in the background after initial setup.
