Are you considering BeautifulSoup or Cheerio for web scraping? Both tools are top-notch HTML parsers used by web scrapers.
In this article, we'll compare BeautifulSoup vs. Cheerio so you can decide the best option for you.
Cheerio vs. BeautifulSoup: Which Is Best?
Cheerio is a Node.js library for parsing HTML and XML documents. It uses jQuery-like syntaxes to locate elements using CSS selectors. JavaScript's asynchronous support allows Cheerio to handle concurrent requests.
BeautifulSoup is an HTML and XML parser package in Python. It builds a parse tree around HTML documents for easy DOM navigation, making it more flexible than Cheerio. Unlike Cheerio, BeautifulSoup is strictly synchronous.
Go with Cheerio If you want to scrape plenty of pages concurrently and faster. Choose BeautifulSoup if you value simplicity and flexibility over speed and concurrency.
Feature Comparison: Cheerio and BeautifulSoup
Let's briefly overview Cheerio vs. BeautifulSoup in a table to see how they compare.
| Consideration | Cheerio | BeautifulSoup |
|---|---|---|
| Language | JavaScript | Python |
| Functionality | HTML and XML parsing | HTML and XML parsing |
| Speed | Fast | Moderate |
| Memory usage | Highly memory-efficient | Moderately memory-efficient |
| Ease of use | Steeper learning curve | Beginner-friendly with an easy learning curve |
| Support for CSS selectors | Yes | Yes |
| Support for XPath | Unsupported | No built-in support. Requires the lxml library |
| Community | Good | Good |
| Documentation | Comprehensive | Comprehensive |
| Avoid getting blocked | Proxy and header rotation with HTTP clients like Axios. | Proxy and header rotation with HTTP clients like Requests. |
| DOM navigation flexibility | Less flexible | Parse tree enhances DOM navigation flexibility |
| Suitability for concurrency | Asynchronous support makes it suitable for concurrency | Not suitable for concurrent scraping |

BeautifulSoup Works with Python, Cheerio with JavaScript
BeautifulSoup and Cheerio are language-specific. Cheerio is a JavaScript library requiring npm installation and the Node.js runtime. BeautifulSoup depends on Python, and installation is via pip.
They're Both Great HTML Parsers
The main similarity between Cheerio and BeautifulSoup is that they both excel as solid HTML parsers in their respective domain. However, BeautifulSoup is more flexible and navigates the DOM better with its XML parse tree capability.
Cheerio is Faster for Parsing
Cheerio is faster than BeautifulSoup at parsing HTML documents, mainly due to Cheerio's asynchronous support and the selection speed it inherits from jQuery.
We did a 100-iteration performance benchmark to compare the parsing speed of BeautifulSoup vs. Cheerio. BeautifulSoup averaged 2.13 seconds to parse the target web page. On average, Cheerio parsed the same web page in 0.32 seconds.
See the graphical presentation of the benchmark below (from the fastest to the slowest).
The time unit used is seconds (s = seconds)
The Two Libraries Are Easy to Use
BeautifulSoup and Cheerio offer straightforward implementations and are easy to set up. However, BeautifulSoup's Pythonic nature makes it more beginner-friendly. Cheerio's dependence on jQuery syntax makes its learning curve a bit steeper for beginners.
Both Tools Have Large Community Support
BeautifulSoup and Cheerio have solid community support in their respective domains. So, there are plenty of resources and guides online to solve problems quickly with both tools.
GitHub statistics place Cheerio above BeautifulSoup in terms of popularity, though. BeautifulSoup polls 717k users, while 1.3 million users depend on Cheerio.
Conclusion
In this article, we've established that BeautifulSoup and Cheerio are effective HTML parsers in their respective languages and share similarities in community support. You've also learned that while BeautifulSoup is easier and more flexible, Cheerio is superior in performance.
Despite their web parsing and scraping functionalities, both tools lack an effective way to bypass blocks, making them vulnerable to anti-bot detection by many websites. Avoid getting blocked with ZenRows and scrape any website without limitations. Try ZenRows for free!
