<summary>🤓 <strong>My Personal Story</strong></summary>

My journey with computers started in childhood when my dad, a computer scientist, introduced me to an Amstrad computer. Those early days sparked a fascination with technology, leading me to pursue computer science and specialize in NLP during my postgraduate studies. It was during this time that I first delved into web crawling, building tools to help researchers organize papers and extract information from publications a challenging yet rewarding experience that honed my skills in data extraction.

Fast forward to 2023, I was working on a tool for a project and needed a crawler to convert a webpage into markdown. While exploring solutions, I found one that claimed to be open-source but required creating an account and generating an API token. Worse, it turned out to be a SaaS model charging $16, and its quality didn’t meet my standards. Frustrated, I realized this was a deeper problem. That frustration turned into turbo anger mode, and I decided to build my own solution. In just a few days, I created Crawl4AI. To my surprise, it went viral, earning thousands of GitHub stars and resonating with a global community.

I made Crawl4AI open-source for two reasons. First, it’s my way of giving back to the open-source community that has supported me throughout my career. Second, I believe data should be accessible to everyone, not locked behind paywalls or monopolized by a few. Open access to data lays the foundation for the democratization of AI, a vision where individuals can train their own models and take ownership of their information. This library is the first step in a larger journey to create the best open-source data extraction and generation tool the world has ever seen, built collaboratively by a passionate community.

Thank you to everyone who has supported this project, used it, and shared feedback. Your encouragement motivates me to dream even bigger. Join us, file issues, submit PRs, or spread the word. Together, we can build a tool that truly empowers people to access their own data and reshape the future of AI.

            url="https://www.nbcnews.com/business",
        )
        print(result.markdown)

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

3. Or use the new command-line interface:
```bash
# Basic crawl with markdown output
crwl https://www.nbcnews.com/business -o markdown

# Deep crawl with BFS strategy, max 10 pages
crwl https://docs.crawl4ai.com --deep-crawl bfs --max-pages 10

## Installation 🛠️

Crawl4AI offers flexible installation options to suit various use cases. You can install it as a Python package or use Docker.

<details>
<summary>🐍 <strong>Using pip</strong></summary>

Choose the installation option that best fits your needs:

### Basic Installation

For basic web crawling and scraping tasks:

```bash
pip install crawl4ai
crawl4ai-setup # Setup the browser
```

By default, this will install the asynchronous version of Crawl4AI, using Playwright for web crawling.

👉 **Note**: When you install Crawl4AI, the `crawl4ai-setup` should automatically install and set up Playwright. However, if you encounter any Playwright-related errors, you can manually install it using one of these methods:

1. Through the command line:

   ```bash
   playwright install
   ```

2. If the above doesn't work, try this more specific command:

   ```bash
   python -m playwright install chromium
   ```

This second method has proven to be more reliable in some cases.

---

### Installation with Synchronous Version

The sync version is deprecated and will be removed in future versions. If you need the synchronous version using Selenium:

```bash
pip install crawl4ai[sync]
```

---

### Development Installation

For contributors who plan to modify the source code:

```bash
git clone https://github.com/unclecode/crawl4ai.git
cd crawl4ai
pip install -e .                    # Basic installation in editable mode
```

Install optional features:

```bash
pip install -e ".[torch]"           # With PyTorch features
pip install -e ".[transformer]"     # With Transformer features
pip install -e ".[cosine]"          # With cosine similarity features
pip install -e ".[sync]"            # With synchronous crawling (Selenium)
pip install -e ".[all]"             # Install all optional features
```

</details>

<details>
<summary>🐳 <strong>Docker Deployment</strong></summary>

> 🚀 **Now Available!** Our completely redesigned Docker implementation is here! This new solution makes deployment more efficient and seamless than ever.

response = requests.post(
    "http://localhost:11235/crawl",
    json={"urls": ["https://example.com"], "priority": 10}
)
if response.status_code == 200:
    print("Crawl job submitted successfully.")
    
if "results" in response.json():
    results = response.json()["results"]
    print("Crawl job completed. Results:")
    for result in results:
        print(result)
else:
    task_id = response.json()["task_id"]
    print(f"Crawl job submitted. Task ID:: {task_id}")
    result = requests.get(f"http://localhost:11235/task/{task_id}")
```

        for result in results:
            if result.success and result.media["tables"]:
                raw_df = pd.DataFrame(
                    result.media["tables"][0]["rows"],
                    columns=result.media["tables"][0]["headers"],
                )

        print(raw_df.head())

    finally:
        await crawler.stop()
  ```

  )
  ```

- **🔌 MCP Integration**: Connect to AI tools like Claude Code through the Model Context Protocol
  ```bash
  # Add Crawl4AI to Claude Code
  claude mcp add --transport sse c4ai-sse http://localhost:11235/mcp/sse
  ```

## Version Numbering in Crawl4AI

Crawl4AI follows standard Python version numbering conventions (PEP 440) to help users understand the stability and features of each release.

### Version Numbers Explained

Our version numbers follow this pattern: `MAJOR.MINOR.PATCH` (e.g., 0.4.3)

#### Pre-release Versions
We use different suffixes to indicate development stages:

- `dev` (0.4.3dev1): Development versions, unstable
- `a` (0.4.3a1): Alpha releases, experimental features
- `b` (0.4.3b1): Beta releases, feature complete but needs testing
- `rc` (0.4.3): Release candidates, potential final version

#### Installation
- Regular installation (stable version):
  ```bash
  pip install -U crawl4ai
  ```

- Install pre-release versions:
  ```bash
  pip install crawl4ai --pre
  ```

- Install specific version:
  ```bash
  pip install crawl4ai==0.4.3b1
  ```

#### Why Pre-releases?
We use pre-releases to:
- Test new features in real-world scenarios
- Gather feedback before final releases
- Ensure stability for production users
- Allow early adopters to try new features

For production environments, we recommend using the stable version. For testing new features, you can opt-in to pre-releases using the `--pre` flag.
