Set `CRAWL4AI_KEY` to your API key, then scrape a page as Markdown:

```bash
curl -s https://api.crawl4ai.com/scrape \
  -H "Authorization: Bearer $CRAWL4AI_KEY" \

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

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. That’s where I learned how much extraction matters.

In 2023, I needed web-to-Markdown. The “open source” 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.

I made it open source for **availability**, anyone can use it without a gate. Now I’m 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.

That platform is live now: [Crawl4AI Cloud](https://crawl4ai.com/?ref=readme).
</details>

<details>
  <summary>Why developers pick Crawl4AI</summary>

- **LLM-ready output**: smart Markdown with headings, tables, code and 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**: run locally with Python or the CLI, secure your Docker server with a self-managed token, or use a Crawl4AI Cloud API key.
</details>

## ✨ Features

<details>
<summary>📝 <strong>Markdown generation</strong></summary>

- 🧹 **Clean Markdown**: headings, lists, tables and code blocks, in a structure an LLM reads well.
- 🎯 **Fit Markdown**: filters remove menus, footers and boilerplate: `PruningContentFilterLXML`, `BM25ContentFilter` (for a query) and `LLMContentFilter`.
- 🔗 **Citations**: page links become a numbered reference list.
- 🛠️ **Your own strategy**: plug in a custom Markdown generator.

☁️ Same in the cloud: `POST /scrape` returns this Markdown, with no browser to run. [Docs →](https://crawl4ai.com/docs?ref=readme#scrape)
</details>

<details>
<summary>📊 <strong>Structured data extraction</strong></summary>

- 🔎 **CSS and XPath schemas**: fast extraction with no LLM (`JsonCssExtractionStrategy`, `JsonXPathExtractionStrategy`, `RegexExtractionStrategy`).
- 🪄 **Schema generator**: describe what you want once; `generate_schema` writes a reusable schema.
- 🤖 **LLM extraction**: any LLM provider, open-source or hosted, into a typed JSON schema (`LLMExtractionStrategy`).
- 🧱 **Chunking**: topic, regex and sentence chunking for long pages.
- 🌌 **Cosine similarity**: find the chunks that match a query (`CosineStrategy`).

☁️ Same in the cloud: `POST /extract`, with no LLM key of your own. [Docs →](https://crawl4ai.com/docs?ref=readme#extract)
</details>

<details>
<summary>🌐 <strong>Browser control</strong></summary>

- 🖥️ **Your own browser**: persistent profiles with saved logins, cookies and settings.
- 🔄 **Remote browsers**: connect over the Chrome DevTools Protocol (CDP).
- 🔒 **Sessions**: keep a browser state across multi-step crawls.
- 🧩 **Proxies**: with authentication and rotation.
- 🕶️ **Stealth mode**: `enable_stealth`, and an undetected-browser adapter for sites that detect automation.
- ⚙️ **Full control**: headers, cookies, user agents, viewport.
- 🌍 **Chromium, Firefox and WebKit**.
</details>

<details>
<summary>🔎 <strong>Crawling and scraping</strong></summary>

- 🕸️ **Deep crawl**: BFS, DFS and best-first strategies, with crash recovery (`resume_state`) for long crawls.
- 🧠 **Adaptive crawling**: `AdaptiveCrawler` stops when it has learned enough to answer your query.
- 🌱 **URL discovery**: `AsyncUrlSeeder` (sitemaps, Common Crawl) and `DomainMapper`; `prefetch=True` finds URLs 5 to 10 times faster.
- 🚀 **Dynamic pages**: run JavaScript, wait for elements, scroll the full page (`scan_full_page`) for infinite scroll and lazy images.
- 📸 **Screenshots and PDFs** of any page.
- 🖼️ **Media and links**: images, audio, video, `srcset`, internal and external links, iframes, metadata.
- 📂 **Raw HTML and local files**: `raw:` and `file://`.
- 🛠️ **Hooks** at every step of a crawl.
- 💾 **Caching** to skip repeated fetches.
- ⚡ **Many URLs at once**: `arun_many` with a memory-adaptive dispatcher.

☁️ Same in the cloud: up to 50 URLs in one streamed call, or 10,000 in a background job. [Docs →](https://crawl4ai.com/docs?ref=readme#batch)
</details>

<details>
<summary>🐳 <strong>Self-hosting (Docker)</strong></summary>

- 🔐 **Secure by default**: every endpoint needs your `CRAWL4AI_API_TOKEN`.
- 🧰 **REST API**: `/md`, `/html`, `/crawl`, `/crawl/stream`, `/screenshot`, `/pdf`, `/execute_js`.
- 🤖 **MCP**: connect Claude Code and other agents to your own server.
- 📊 **Monitoring dashboard and playground**, a browser pool with pre-warmed pages.
- 🏗️ **AMD64 and ARM64** images.

<details>
<summary>☁️ <strong>What the cloud adds</strong></summary>

- 🔍 **Web search API**: `GET /search`, browser-free, ranked and cleaned. [Docs →](https://crawl4ai.com/docs?ref=readme#search)
- 📊 **SERP API**: `GET /serp`, Google's results page as data: true ranks, every block, localised to a place. Beta. [Docs →](https://crawl4ai.com/docs?ref=readme#serp)
- 💬 **Answers**: `GET /answer` gives a direct answer to a question (experimental). [Docs →](https://crawl4ai.com/docs?ref=readme#answer)
- 🧪 **Extraction without your own LLM key**: `POST /extract`. [Docs →](https://crawl4ai.com/docs?ref=readme#extract)
- 🧗 **JS-heavy pages and bot walls**: handled automatically; you never pick an engine. [Docs →](https://crawl4ai.com/docs?ref=readme#scrape)
- 🤝 **MCP for your agent**: one line in Claude Code, Codex, Cursor or OpenCode. [Docs →](https://crawl4ai.com/docs?ref=readme#mcp)

<a id="installation"></a>

## 🛠️ Installation

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

```bash
pip install -U crawl4ai
crawl4ai-setup      # installs and sets up the browser
crawl4ai-doctor     # checks the installation
```

If the browser setup fails, install it by hand:

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

Pre-release versions: `pip install crawl4ai --pre`

**Development install**, for contributors:

```bash
git clone https://github.com/unclecode/crawl4ai.git
cd crawl4ai
pip install -e ".[all]"     # or: pip install -e .   (the core only)
```
</details>

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

The server needs a token. Without one it answers only inside its container.

```bash
export CRAWL4AI_API_TOKEN="$(openssl rand -hex 32)"
docker run -d -p 11235:11235 --name crawl4ai --shm-size=1g \
  -e CRAWL4AI_API_TOKEN="$CRAWL4AI_API_TOKEN" \
  unclecode/crawl4ai:latest
```

Test it (allow about 10 seconds for the start):

```bash
curl -s http://localhost:11235/md \
  -H "Authorization: Bearer $CRAWL4AI_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://news.ycombinator.com"}' | jq -r .markdown
```

The dashboard is at `http://localhost:11235/dashboard`, the playground at `http://localhost:11235/playground`. LLM keys, MCP and every setting: [Self-hosting guide](https://docs.crawl4ai.com/core/self-hosting/).
</details>

<details>
<summary>⌨️ <strong>Command line (`crwl`)</strong></summary>

```bash
# A page as Markdown
crwl https://news.ycombinator.com -o markdown

# Deep crawl, breadth first, at most 10 pages
crwl https://docs.crawl4ai.com --deep-crawl bfs --max-pages 10

# Ask a question about a page (needs an LLM key: crwl config)
crwl https://www.example.com/products -q "Extract all product prices"
```
