This article has been updated to include the new Crawlee for Python library. See how it compares to other web scraping libraries and frameworks in the Python ecosystem.
Web scraping is essentially a way to automate the process of extracting data from the web. Python has some of the best libraries and frameworks available to help you get the job done.
What follows are the most popular libraries and frameworks for web scraping in Python: their features, pros and cons, alternatives, and code examples.
Know exactly what tool to use to tackle any web scraping project you might come across.
1. Crawlee
Crawlee is a complete web scraping and browser automation library designed to “help you build reliable crawlers fast”. Crawlee for Node.js and TypeScript was launched in the summer of 2022. Crawlee for Python was released in July 2024 and has already garnered over 3,500 stars on GitHub.
✨ Features
- A unified interface for HTTP and headless browsers.
- Type hint coverage and code maintainability.
- Automatic parallel crawling.
- Persistent queue for URLs to crawl.
- Integrated proxy rotation and session management.
- Configurable request routing.
- Automatic error handling.
- Pluggable storage of both tabular data and files.
👍 Pros

2. Requests
Every scraping job starts by making a request to a website and retrieving its contents, usually as HTML. Requests is an HTTP library designed to make this task simple, earning its tagline, "HTTP for humans." That's why the Python Requests library is the most downloaded Python package.
✨ Features
- Simple and intuitive API for making HTTP requests.
- Handles GET, POST, PUT, DELETE, HEAD, and OPTIONS requests.
- Automatically decodes content based on the response headers.
- Allows for persistent connections across requests.
- Built-in support for SSL/TLS verification, with the option to bypass it.
- Easily add headers, parameters, and cookies to requests.
- Set timeouts and retry policies for requests.
- Supports large file downloads by streaming responses in chunks.
- Supports proxy configuration.
👍 Pros
- Simplifies complex HTTP tasks with a clean and readable syntax.
- Large user base and community support.
- Well-documented with numerous examples and guides.
👎 Cons
- Not as fast as some lower-level libraries like
http.client
orurllib3
for highly performance-sensitive applications. - Lacks built-in asynchronous capabilities, requiring additional libraries like
asyncio
oraiohttp
for non-blocking requests. - The library can be considered heavy for minimalistic environments or resource-constrained applications.
🤔 Alternatives
httpx, urlib3, http.client, aiohttp
🔰 Install Requests
To install the Requests library, use pip, the Python package manager:
pip install requests
📜 Code example
3. HTTPX
HTTPX is another HTTP library, but what makes it different from Requests is it offers some advanced features like async and HTTP/2 support. HTTPX and Requests have a very similar core functionality. So we recommend HTTPX even for smaller projects since you can easily scale up in the future without compromising performance.
✨ Features
- Built-in async capabilities using
asyncio
, allowing for non-blocking HTTP requests. - Natively supports HTTP/2 for improved performance over HTTP/1.1.
- Offers both sync and async interfaces to provide flexibility based on your needs.
- Efficient management of connections with automatic connection pooling.
- Automatically follows redirects, similar to Requests, but with more control over redirection behavior.
- Ability to customize the HTTP transport, including the use of custom connection pools and proxies.
- Supports streaming responses, cookie management, and multipart uploads.
👍 Pros
- Allows for non-blocking requests, which makes it ideal for I/O-bound tasks or applications requiring high concurrency.
- Built with modern web standards and practices in mind, including HTTP/2 support.
👎 Cons
- For developers unfamiliar with asynchronous programming, there may be a steeper learning curve compared to Requests.
- While rapidly gaining popularity, it is newer than Requests and may have a smaller community and fewer resources available.
🤔 Alternatives
Requests, aiohttp, urlib3, http.client
🔰 Install HTTPX
To install the HTTPX library, use pip, the Python package manager:
pip install httpx
📜 Code example
4. Beautiful Soup
Once you have HTML content, you need a way to parse it and extract the data you're interested in. Enter Beautiful Soup, one of the most popular Python HTML parsers. It lets you navigate and search through the HTML tree structure easily. Its straightforward syntax and easy setup also make Beautiful Soup a great option for small- to medium-sized web scraping projects and web scraping beginners.
✨ Features
- HTML/XML parsing
- Navigation of parse trees
- Handles different encodings and automatically converts documents to Unicode, ensuring compatibility.
- Works with multiple parsers like lxml, html.parser, and html5lib, offering flexibility in handling different parsing needs.
- Easily access and modify tags, attributes, and text within the document.
👍 Pros
- Designed to be simple and easy to use, even for beginners, with a gentle learning curve.
- Works well with a variety of parsing libraries and is adaptable to different scraping tasks.
- Comprehensive documentation and numerous tutorials available, making it easy to get started.
- Effectively parses and extracts data from poorly structured HTML, which is common on the web.
- Popular in the web scraping community, ensuring plenty of resources and community-driven solutions.
👎 Cons
- Limited scalability
- Inability to scrape JavaScript-heavy websites
🤔 Alternatives
lxml, html5lib
🔰 Install Beautiful Soup
To install Beautiful Soup, use pip to install the package beautifulsoup4
. We also recommend installing lxml
or html5lib
for better parsing capabilities:
pip install beautifulsoup4 lxml
📜 Code example
5. Mechanical Soup
Mechanical Soup is a Python library that acts as a higher-level abstraction over the popular Requests and BeautifulSoup libraries. It simplifies the process of web scraping by combining the ease of use of Requests with the HTML parsing capabilities of Beautiful Soup.
✨ Features
- Streamlines the process of making HTTP requests to websites and makes it easy to fetch web pages and interact with them
- Integrates with Beautiful Soup's powerful HTML parsing capabilities to allow easy data extraction from websites
- Has convenient methods for submitting HTML forms on web pages, which simplifies automated interaction with websites that require form submission
- Supports session management and helps maintain stateful interactions with websites across multiple requests
- Like Requests, Mechanical Soup offers support for proxy configuration and allows to scrape data anonymously or bypass IP restrictions
👍 Pros
- Provides a simplified interface for web scraping tasks
- Seamless integration with Beautiful Soup for HTML parsing
- Supports form submission and session handling
- Offers proxy support for anonymity and bypassing restrictions
👎 Cons
- Limited advanced features compared to Crawlee, Scrapy, or Playwright.
- May not be suitable for complex or large-scale scraping projects.
🤔 Alternatives

pip install selenium
📜 Code example
7. Playwright
Playwright is a modern web automation framework developed by Microsoft. It offers powerful capabilities for interacting with web pages, supporting multiple browsers (Chromium, Firefox, WebKit) with a single API. Playwright is highly favored for testing and automation due to its speed, reliability, and ability to handle complex web applications. Like Selenium, it's a powerful tool for web scraping when dealing with websites that require dynamic content loading.
✨ Features
