These are the best Open Source web scraper tools available in each language or platform :


puppeteer-web-scraping-frameworkPuppeteer is a Node library which provides a powerful but simple API that allows you to control Google’s headless Chrome browser. A headless browser means you have a browser that can send and receive requests but has no GUI. It works in the background, performing actions as instructed by an API. You can truly simulate the user experience, typing where they type and clicking where they click.

The best case to use Puppeteer for web scraping is if the information you want is generated using a combination of API data and JavaScript code. A headless browser is a great tool for automated testing and server environments where you don’t need a visible UI shell. For example, you may want to run some tests against a real web page, create a PDF of it, or just inspect how the browser renders a URL. Puppeteer can also be used to take screenshots of web pages visible by default when you open a web browser. Puppeteer’s API is very similar to Selenium WebDriver, but works only with Google Chrome, while WebDriver works with most popular browsers. Puppeteer has a more active support than Selenium, so if you are working with Chrome, Puppeteer is your best option for web scraping.

Requires Version – Node v6.4.0, Node v7.6.0 or greater

Available Selectors – CSS

Available Data Formats – JSON


  • With its full-featured API, it covers a majority of use cases
  • The best option for scraping JavaScript websites on Chrome

Scrapy is an open source web scraping framework in Python used to build web scrapers. It gives you all the tools you need to efficiently extract data from websites, process them as you want, and store them in your preferred structure and format. One of its main advantages is that it’s built on top of a Twisted asynchronous networking framework. If you have a large web scraping project and want to make it as efficient as possible with a lot of flexibility then you should definitely use Scrapy. 

Scrapy has a couple of handy built-in export formats such as JSON, XML, and CSV. Its built for extracting specific information from websites and allows you to focus on the data extraction using CSS selectors and choosing XPath expressions. Scraping web pages using Scrapy is much faster than other open source tools so its ideal for extensive large-scale scaping. It can also be used for a wide range of purposes, from data mining to monitoring and automated testing. What stands out about Scrapy is its ease of use and detailed documentation. If you are familiar with Python you’ll be up and running in just a couple of minutes. It runs on Linux, Mac OS, and Windows systems.

Scrapy is under BSD license.

Requires Version – Python 2.7, 3.4+

Available Selectors – CSS, XPath

Available Data Formats – CSV, JSON, XML


  • Suitable for broad crawling
  • Easy setup and detailed documentation
  • Active community


  • Since it is a full-fledged framework, it is not beginner friendly
  • Does not handle JavaScript

Selenium WebDriver

selenium-web-scraping-toolWhen it comes to websites that use very complex and dynamic code, it’s better to have all the page content rendered using a browser first. Selenium WebDriver uses a real web browser to access the website, so it would like its activity wouldn’t look any different from a real person accessing information in the same way. When you load a page using Web Driver, the browser loads all the web resources and executes the javaScript on the page. At the same time, it stores all the cookies created by websites and sends complete HTTP headers as all browsers do. This makes it very hard to determine whether a real person accesses the website or if its a bot.

Although it’s mostly used for testing, WebDriver can be used for scraping dynamic web pages. It is the right solution if you want to test if a website works properly with various browsers or JavaScript-heavy websites. Using WebDriver makes web scraping easier, but the scraping process is much slower as compared to simple HTTP request to the web browser. When you are using the WebDriver, the browser waits until the whole page is loaded and then can you only access the elements. Selenium has a very large and active community which is great for beginners.

Requires Version – Python 2.7 and 3.5+ and provides bindings for languages JavaScript, Java, C, Ruby, and Python.

Available Selectors – CSS, XPath

Available Data Formats – Customizable


  • Suitable for scraping heavy JavaScript websites

  • Hard to maintain when there are any changes in the website structure
  • High CPU and memory usage


pyspider-web-crawler-toolPySpider is a web crawler written in Python. It supports JavaScript pages and has a distributed architecture. This way you can have multiple crawlers. PySpider can store the data on a backend of your choosing such as MongoDB, MySQL, Redis, etc. You can use RabbitMQ, Beanstalk, and Redis as message queues.

One of the advantages of PySpider its easy to use UI where you can edit scripts, monitor ongoing tasks and view results. If you are working with a website-based user interface, PySpider is the internet scrape to consider. It also supports AJAX heavy websites. To know more about PySpider, you can check out their documentation and or their community resources. It’s currently licensed under Apache License 2.0.

Requires Version – Python 2.6+, Python 3.3+

Available Selectors – CSS, XPath

Available Data Formats – CSV, JSON


  • Facilitates more comfortable and faster scraping
  • Powerful UI


  • Difficult to deploy


crawleeCrawlee, is the successor to Apify SDK which is a Node.js library and positions itself as a universal web scraping library in JavaScript, with support for Puppeteer, Cheerio, and more. Crawlee has full TypeScript support, anti-blocking features, and a similar Apify SDK interface. It also retains all the web crawling and scraping-related tools.

Requirements – Crawlee requires Node.js 16 or higher
Available Selectors – CSS
Available Data Formats – JSON, JSONL, CSV, XML, Excel or HTML


  • Runs on Node.js and it’s built in TypeScript to improve code completion
  • Automatic scaling and proxy management
  • Mimic browser headers and TLS fingerprints


  • Single Actors (scrapers) occasionally break causing delays in data scraping
  • The interface is a bit difficult to navigate, especially for new users


Add Crawlee to any Node.js project by running:

npm install crawlee

Best Use Case

If you need a better developer experience and powerful anti-blocking features.


nodecrawler-web-scraping-frameworkNodeCrawler is a popular web crawler for NodeJS, making it a very fast crawling solution. If you prefer coding in JavaScript, or you are dealing with mostly a JavaScript project, NodeCrawler will be the most suitable web crawler to use. Its installation is pretty simple too. JSDOM and Cheerio (used for HTML parsing) use it for server-side rendering, with JSDOM being more robust.

Requires Version – Node v4.0.0 or greater

Available Selectors – CSS, XPath

Available Data Formats – CSV, JSON, XML


  • Easy installation


  • It has no Promise support


web-scraping-python-library-mechanical-soupMechanicalSoup is a Python library that is designed to simulate the behavior of a human using a web browser and built around the parsing library BeautifulSoup. If you need to scrape data from simple sites or if heavy scraping is not required, using MechanicalSoup is a simple and efficient method. MechanicalSoup automatically stores and sends cookies, follows redirects and can follow links and submit forms.

It’s best to use MechanicalSoup when interacting with a website that doesn’t provide a web service API, out of a browser. If the website provides a web service API, then you should use this API and you don’t need MechanicalSoup. If the website relies on JavaScript, then you probably need a fully-fledged browser, like Selenium. MechanicalSoup is licensed under MIT.

Requires Version – Python 3.0+

Available Selectors – CSS, XPath

Available Data Formats – CSV, JSON, XML


  • Preferred for fairly simple websites


  • Does not handle JavaScript
