8 Most Popular Python HTML Web Scraping Packages with Benchmarks

Intro

This blog post will cover Python web scraping packages in terms of their speed, ease of use, and personal investigations. This blog post won't cover what webscraping is and how parsers work.

By the end of this blog post, you'll understand or have a better understanding of which parser/browser automation to use for your purpose.

This blog post is split into two parts:

Python HTML parsers and their benchmarks.
Python browser automation packages and their benchmarks.

The first section will be about speed comparison and ease of use. The second section will be specifically about Python's browser automation packages, memory consumption, and speed.

📌Please note that I'm not very advanced in benchmarking, feel free to comment on what feels wrong or confusing.

Python Parsers Benchmarks

This section will compare 5 Python HTML parsers:

html.parser
html5lib
lxml
parsel
selectolax (HTML, Lexbor backends)

There're four tests with saved locally Google Organic search results HTML file:

100 iterations with 10 repeats.
500 iterations with 10 repeats.
1000 iterations with 10 repeats.
3000 iterations with 5 repeats.

Personal Investigations

html5lib is the slowest parser of all of the mentioned parsers.
BeautifulSoup html.parser and lxml parser has a very slight change in results. Interesting that in 3000 iterations bs4 lxml backend was slower. Didn't understand why.
It's interesting that lxml parser is used in both bs4 and parsel but parsel outperforms bs4 with lxml backend.
selectolax HTML and Lexbor parsers are incredibly fast. Besides speed, I've noticed (not measured in this blog post) that the Lexbor parser used almost half less memory compared to all other parsers.
lxml was the hardest to use as it required XPath knowledge. This point is subjective, however, worth noting. Writing XPath takes some time and some additional knowledge. If you were writing XPath before, then there'll be no issues.
selectolax in terms of syntax is very similar to both bs4 and parsel, which is handy. One thing to keep in mind is that selectolax currently doesn't support XPath.

Python Browser Automation

The test was fairly basic to see memory consumption, and speed. Each script makes a request to Google Search and paginates through 10 pages.

Browser Automation Profiling Results

Tests were run with the following command:

$ mprof run <file_name>.py
$ mprof plot # to plot the results (matplotlib is required)

Personal Investigations

Surprisingly selenium was a little faster than requests-html. Or maybe not surprisingly :)
playwright was the slowest.
selenium had a hard time with complex CSS selectors, for example .d6cvqb a[id=pnnext] (.get_attribute() also didn't work). That's why for in range() was used instead. I know it can be done with XPath but I wanted to use CSS selectors only, although requests-html uses only XPath.
Memory consumption was pretty much identical between the 3 packages.

Conclusions

If you need to scrape data from a dynamic page that doesn't require clicking, scrolling and similar things but still requires rendering JavaScript, try requests-html. It uses pure XPath as lxml and should be faster than the other two browser automations.
If you need to do complex page manipulation on the dynamic page, try to use playwright or selenium.
If you scraping non-dynamic pages (rendered via JavaScript), try selectolax over bs4, lxml or parsel. It's a lot faster, uses less memory, and has almost identical syntax to parsel or bs4. A hidden gem I would say.
If you need to use XPath in your parser, try to use either lxml or parsel. parsel is built on top of lxml and translates every CSS query to XPath and can combine (chain) CSS and XPath queries. However, lxml is faster.
