    <small>A web scraping and browser automation library</small>
</h1>

Crawlee covers your crawling and scraping end-to-end and **helps you build reliable scrapers. Fast.**

> 🚀 Crawlee for Python is open to early adopters!

Your crawlers will appear almost human-like and fly under the radar of modern bot protections even with the default configuration. Crawlee gives you the tools to crawl the web for links, scrape data and persistently store it in machine-readable formats, without having to worry about the technical details. And thanks to rich configuration options, you can tweak almost any aspect of Crawlee to suit your project's needs if the default settings don't cut it.

> 👉 **View full documentation, guides and examples on the [Crawlee project website](https://crawlee.dev/python/)** 👈

We also have a TypeScript implementation of the Crawlee, which you can explore and utilize for your projects. Visit our GitHub repository for more information [Crawlee for JS/TS on GitHub](https://github.com/apify/crawlee).

## Installation

We recommend visiting the [Introduction tutorial](https://crawlee.dev/python/docs/introduction) in Crawlee documentation for more information.

Crawlee is available as the [`crawlee`](https://pypi.org/project/crawlee/) PyPI package.

```sh
pip install crawlee
```

Additional, optional dependencies unlocking more features are shipped as package extras.

If you plan to parse HTML and use CSS selectors, install `crawlee` with `beautifulsoup` extra:

```sh
pip install 'crawlee[beautifulsoup]'
```

If you plan to use a (headless) browser, install `crawlee` with the `playwright` extra:

```sh
pip install 'crawlee[playwright]'
```

Then, install the Playwright dependencies:

```sh
playwright install
```

You can install multiple extras at once by using a comma as a separator:

```sh
pip install 'crawlee[beautifulsoup,playwright]'
```

Verify that Crawlee is successfully installed:

```sh
python -c 'import crawlee; print(crawlee.__version__)'
```

### With Crawlee CLI

The quickest way to get started with Crawlee is by using the Crawlee CLI and selecting one of the prepared templates. First, ensure you have [Pipx](https://pipx.pypa.io/) installed:

```sh
pipx --help
```

Then, run the CLI and choose from the available templates:

```sh
pipx run crawlee create my-crawler
```

If you already have `crawlee` installed, you can spin it up by running:

```sh
crawlee create my-crawler
```

## Examples

Here are some practical examples to help you get started with different types of crawlers in Crawlee. Each example demonstrates how to set up and run a crawler for specific use cases, whether you need to handle simple HTML pages or interact with JavaScript-heavy sites. A crawler run will create a `storage/` directory in your current working directory.

### BeautifulSoupCrawler

The `BeautifulSoupCrawler` downloads web pages using an HTTP library and provides HTML-parsed content to the user. It uses [HTTPX](https://pypi.org/project/httpx/) for HTTP communication and [BeautifulSoup](https://pypi.org/project/beautifulsoup4/) for parsing HTML. It is ideal for projects that require efficient extraction of data from HTML content. This crawler has very good performance since it does not use a browser. However, if you need to execute client-side JavaScript, to get your content, this is not going to be enough and you will need to use PlaywrightCrawler. Also if you want to use this crawler, make sure you install `crawlee` with `beautifulsoup` extra.

```python
import asyncio

from crawlee.beautifulsoup_crawler import BeautifulSoupCrawler, BeautifulSoupCrawlingContext


async def main() -> None:
    crawler = BeautifulSoupCrawler(
        # Limit the crawl to max requests. Remove or increase it for crawling all links.
        max_requests_per_crawl=10,
    )

    # Define the default request handler, which will be called for every request.
    @crawler.router.default_handler
    async def request_handler(context: BeautifulSoupCrawlingContext) -> None:
        context.log.info(f'Processing {context.request.url} ...')

        # Extract data from the page.
        data = {
            'url': context.request.url,
            'title': context.soup.title.string if context.soup.title else None,
        }

        # Push the extracted data to the default dataset.
        await context.push_data(data)

        # Enqueue all links found on the page.
        await context.enqueue_links()

    # Run the crawler with the initial list of URLs.
    await crawler.run(['https://crawlee.dev'])

if __name__ == '__main__':
    asyncio.run(main())
```

### PlaywrightCrawler

The `PlaywrightCrawler` uses a headless browser to download web pages and provides an API for data extraction. It is built on [Playwright](https://playwright.dev/), an automation library designed for managing headless browsers. It excels at retrieving web pages that rely on client-side JavaScript for content generation, or tasks requiring interaction with JavaScript-driven content. For scenarios where JavaScript execution is unnecessary or higher performance is required, consider using the `BeautifulSoupCrawler`. Also if you want to use this crawler, make sure you install `crawlee` with `playwright` extra.

```python
import asyncio

from crawlee.playwright_crawler import PlaywrightCrawler, PlaywrightCrawlingContext


async def main() -> None:
    crawler = PlaywrightCrawler(
        # Limit the crawl to max requests. Remove or increase it for crawling all links.
        max_requests_per_crawl=10,
    )

    # Define the default request handler, which will be called for every request.
    @crawler.router.default_handler
    async def request_handler(context: PlaywrightCrawlingContext) -> None:
        context.log.info(f'Processing {context.request.url} ...')

        # Extract data from the page.
        data = {
            'url': context.request.url,
            'title': await context.page.title(),
        }

        # Push the extracted data to the default dataset.
        await context.push_data(data)

        # Enqueue all links found on the page.
        await context.enqueue_links()

    # Run the crawler with the initial list of requests.
    await crawler.run(['https://crawlee.dev'])


if __name__ == '__main__':
    asyncio.run(main())
```

## Features

Why Crawlee is the preferred choice for web scraping and crawling?

### Why use Crawlee instead of just a random HTTP library with an HTML parser?

- Unified interface for **HTTP & headless browser** crawling.
- Automatic **parallel crawling** based on available system resources.
- Written in Python with **type hints** - enhances DX (IDE autocompletion) and reduces bugs (static type checking).
- Automatic **retries** on errors or when you’re getting blocked.
- Integrated **proxy rotation** and session management.
- Configurable **request routing** - direct URLs to the appropriate handlers.
- Persistent **queue for URLs** to crawl.
- Pluggable **storage** of both tabular data and files.
- Robust **error handling**.

### Why to use Crawlee rather than Scrapy?

- Crawlee has out-of-the-box support for **headless browser** crawling (Playwright).
- Crawlee has a **minimalistic & elegant interface** - Set up your scraper with fewer than 10 lines of code.
- Complete **type hint** coverage.
- Based on standard **Asyncio**.

## Running on the Apify platform
