Are you weighing your options between Scrapy vs. BeautifulSoup for web scraping? Their similarities can be confusing, but each has specific use cases.
In this article, we'll analyze the similarities and differences between Scrapy and BeautifulSoup.
Scrapy vs. BeautifulSoup: Which Is Best?
Scrapy is a Python web scraping and crawling framework that can make HTTP requests to a web page, parse it, and extract data from it. It features all the tools for collecting and organizing data.
BeautifulSoup is a parsing library in Python for extracting data from HTML and XML documents. Unlike Scrapy, it relies on external HTTP clients to send requests.
Choose BeautifulSoup for a simple way to scrape static HTML content from a web page quickly. Scrapy is ideal for large-scale web scraping that requires extracting content from multiple web pages.
Overview: Scrapy vs. BeautifulSoup
Here's a table to overview the comparison between Scrapy vs. BeautifulSoup.
Feature | Scrapy | BeautifulSoup |
---|---|---|
Language | Python | Python |
Ease of Use | Requires extra setup | Easy to use |
Speed | Fair | Fast |
Memory Usage | Fair | Memory-efficient |
Parsing Methods | Built on Parsel library. CSS and XPath selectors | Tag-based, XPath with lxml parser, DOM tree navigation |
Data Export | Built-in via settings feed, CSV, JSON, XML | Relies on external libraries like Pandas |
HTTP Request | Yes | No |
JS Rendering | Scrapy Splash | BeautifulSoup with Selenium |
Now, let's dive deeper into the similarities and differences between Scrapy vs. BeautifulSoup.
Similarities Between Scrapy and BeautifulSoup
The comparison of BeautifulSoup vs. Scrapy isn't complete without considering their similarities. Let's see what they share in common.
Both Parse HTML and Beyond
Scrapy and BeautifulSoup go through a similar parsing cycle. Both tools parse web pages as HTML or XML documents, read their elements, and extract the required data from target elements.
Many Integrations Available
The functionalities of BeautifiulSoup and Scrapy are extensible with extra integrations.
Both tools support third-party Python libraries for HTTP requests, JavaScript rendering, data storage, data processing and export, and authentication handling.
Great Parsing Performance
Scrapy and BeautifulSoup are known for their efficient performance. However, BeautifulSoup is a bit faster, considering it's lighter than Scrapy.
We did a 100-iteration performance benchmark to compare the content extraction speed of Scrapy vs. BeautifulSoup and computed the average time.
It took Scrapy 6.42 seconds to scrape the target content. As expected, BeautifulSoup was faster at 3.47 seconds.
See the graphical result below.
The time unit used is the second (s = seconds).
Active Community Support
Scrapy and BeautifulSoup have active community support, and you'll find many online discussions about each tool to solve problems quickly.
BeautifulSoup is more popular than Scrapy, with approximately 710k users, while Scrapy only has 40.4k users. But this is a fair share considering BeautifulSoup's simplicity and Scrapy's usage in more complex scenarios.
Main Differences: Scrapy and BeautifulSoup
Although they share some similarities, let's consider the attribute that sets Scrapy vs. BeautifulSoup apart.
Scrapy as a Full Scraping Framework, BeautifulSoup for Parsing
Scrapy is a full-fledged web scraping framework with all the essential web scraping and crawling tools. BeautifulSoup is only a parser library for navigating and collecting content from HTML and XML documents.
Scrapy Is Better for Large-Scale Crawling
Scrapy's asynchronous design allows it to scrape multiple pages concurrently. So, it's suitable for medium to large-scale web crawling and data extraction.
BeautifulSoup lacks web crawling ability and best suits smaller and focused scraping tasks.
Scrapy Packs More Features, BeautifulSoup Stays Focused
BeautifulSoup is only an HTML and XML parser that makes it easy to extract data from web pages. It relies on third-party tools for extra functionalities like requests, crawling, and data handling.
Scrapy packs many built-in features for sending requests, parsing, crawling, collecting, and organizing data. This eliminates over-reliance on third-party tools.
Also you can spoof a browser's TLS using handlers like Scrapy-impersonate.
BeautifulSoup Is Easier to Learn Than Scrapy
BeautifulSoup wins in terms of implementation simplicity and smooth learning curve. Unlike Scrapy, it doesn't require extra project setup besides library installation.
Scrapy has a more sophisticated design with extra setup steps and many configurable parts, making it hard for beginner scrapers.

Best Choice to Avoid Getting Blocked While Scraping
Your scraper needs to avoid anti-bot detection to scrape all the data you want. BeautifulSoup and Scrapy offer solutions to avoid getting blocked during scraping.
For instance, employing various JavaScript middleware in Scrapy can add a human touch to your scraper and prevent anti-bot detection. Another way to avoid detection is to route Scrapy through a proxy.
BeautifulSoup also supports proxy and header customization to prevent anti-bot detection.
However, the straightforward solution to avoid getting blocked is to use a web scraping API like ZenRows. ZenRows integrates perfectly with Scrapy, allowing you to scrape any website without getting blocked. Try ZenRows for free!
Conclusion
The choice between Scrapy vs. BeautifulSoup depends on your scraping goal. Both tools have similarities and differences. While BeautifulSoup focuses on parsing and has an easier learning curve, Scrapy is superior in versatility and scalability and is more suitable for large-scale web scraping.
With that said, extracting the data you need isn't often the problem, but getting blocked while scraping is. That's why a solution like ZenRows exists to help you bypass blocks and scrape any website. Try ZenRows for free today!
