๐ค My Personal Story
I grew up on an Amstrad, thanks to my dad, and never stopped building. In grad school I specialized in NLP and built crawlers for research. Thatโs where I learned how much extraction matters.
In 2023, I needed web-to-Markdown. The โopen sourceโ option wanted an account, API token, and $16, and still under-delivered. I went turbo anger mode, built Crawl4AI in days, and it went viral. Now itโs the most-starred crawler on GitHub.
I made it open source for **availability**, anyone can use it without a gate. Now Iโm building the platform for **affordability**, anyone can run serious crawls without breaking the bank. If that resonates, join in, send feedback, or just crawl something amazing.
Why developers pick Crawl4AI
- **LLM ready output**, smart Markdown with headings, tables, code, citation hints
- **Fast in practice**, async browser pool, caching, minimal hops
- **Full control**, sessions, proxies, cookies, user scripts, hooks
- **Adaptive intelligence**, learns site patterns, explores only what matters
- **Deploy anywhere**, zero keys, CLI and Docker, cloud friendly
## ๐ Quick Start
1. Install Crawl4AI:
```bash
# Install the package
pip install -U crawl4ai
# For pre release versions
pip install crawl4ai --pre
# Run post-installation setup
crawl4ai-setup
# Verify your installation
crawl4ai-doctor
```
If you encounter any browser-related issues, you can install them manually:
```bash
python -m playwright install --with-deps chromium
```
2. Run a simple web crawl with Python:
```python
import asyncio
from crawl4ai import *
async def main():
async with AsyncWebCrawler() as crawler:
result = await crawler.arun(
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
# Use LLM extraction with a specific question
crwl https://www.example.com/products -q "Extract all product prices"
```

## Installation ๐ ๏ธ
Crawl4AI offers flexible installation options to suit various use cases. You can install it as a Python package or use Docker.
๐ Using pip
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.
๐ **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
```
๐ณ Docker Deployment
> ๐ **Now Available!** Our completely redesigned Docker implementation is here! This new solution makes deployment more efficient and seamless than ever.
### New Docker Features
The new Docker implementation includes:
- **Real-time Monitoring Dashboard** with live system metrics and browser pool visibility
- **Browser pooling** with page pre-warming for faster response times
- **Interactive playground** to test and generate request code
- **MCP integration** for direct connection to AI tools like Claude Code
- **Comprehensive API endpoints** including HTML extraction, screenshots, PDF generation, and JavaScript execution
- **Multi-architecture support** with automatic detection (AMD64/ARM64)
- **Optimized resources** with improved memory management
### Getting Started
```bash
# Pull and run the latest release
docker pull unclecode/crawl4ai:latest
docker run -d -p 11235:11235 --name crawl4ai --shm-size=1g unclecode/crawl4ai:latest
# Visit the monitoring dashboard at http://localhost:11235/dashboard
# Or the playground at http://localhost:11235/playground
```
### Quick Test
Run a quick test (works for both Docker options):
```python
import requests
# Submit a crawl job
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}")
```

[Full v0.7.3 Release Notes โ](https://github.com/unclecode/crawl4ai/blob/main/docs/blog/release-v0.7.3.md)
Version 0.7.0 Release Highlights - The Adaptive Intelligence Update
- **๐ง Adaptive Crawling**: Your crawler now learns and adapts to website patterns automatically:
```python
config = AdaptiveConfig(
confidence_threshold=0.7, # Min confidence to stop crawling
max_depth=5, # Maximum crawl depth
max_pages=20, # Maximum number of pages to crawl
strategy="statistical"
)
async with AsyncWebCrawler() as crawler:
adaptive_crawler = AdaptiveCrawler(crawler, config)
state = await adaptive_crawler.digest(
start_url="https://news.example.com",
query="latest news content"
)
# Crawler learns patterns and improves extraction over time
```
- **๐ Virtual Scroll Support**: Complete content extraction from infinite scroll pages:
```python
scroll_config = VirtualScrollConfig(
container_selector="[data-testid='feed']",
scroll_count=20,
scroll_by="container_height",
wait_after_scroll=1.0
)
result = await crawler.arun(url, config=CrawlerRunConfig(
virtual_scroll_config=scroll_config
))
```
- **๐ Intelligent Link Analysis**: 3-layer scoring system for smart link prioritization:
```python
link_config = LinkPreviewConfig(
query="machine learning tutorials",
score_threshold=0.3,
concurrent_requests=10
)
result = await crawler.arun(url, config=CrawlerRunConfig(
link_preview_config=link_config,
score_links=True
))
# Links ranked by relevance and quality
```
- **๐ฃ Async URL Seeder**: Discover thousands of URLs in seconds:
```python
seeder = AsyncUrlSeeder(SeedingConfig(
source="sitemap+cc",
pattern="*/blog/*",
query="python tutorials",
score_threshold=0.4
))
urls = await seeder.discover("https://example.com")
```
- **โก Performance Boost**: Up to 3x faster with optimized resource handling and memory efficiency

## Version Numbering in Crawl4AI
Crawl4AI follows standard Python version numbering conventions (PEP 440) to help users understand the stability and features of each release.
๐ 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.
