Crawlee is a modern web scraping and browser automation framework for JavaScript and TypeScript, built by Apify. It is the successor to the Apify SDK and provides a unified interface for building reliable web scrapers and crawlers that can scale from simple scripts to large-scale data extraction projects.

Crawlee supports multiple crawling strategies through different crawler classes:

  • CheerioCrawler For fast, lightweight HTML scraping using Cheerio (no browser needed). Best for static pages.
  • PlaywrightCrawler Uses Playwright for full browser automation. Handles JavaScript-rendered pages, SPAs, and complex interactions.
  • PuppeteerCrawler Similar to PlaywrightCrawler but uses Puppeteer as the browser automation backend.
  • HttpCrawler Minimal crawler for raw HTTP requests without HTML parsing.

Key features include:

  • Automatic request queue management with configurable concurrency and rate limiting
  • Built-in proxy rotation with session management
  • Persistent request queue and dataset storage (local or cloud via Apify)
  • Automatic retry and error handling with configurable strategies
  • TypeScript-first design with full type safety
  • Middleware-like request/response hooks (preNavigationHooks, postNavigationHooks)
  • Output pipelines for storing extracted data
  • Easy deployment to Apify cloud platform

Crawlee is considered the most feature-complete web scraping framework in the JavaScript/TypeScript ecosystem, comparable to Python's Scrapy but with native browser automation support.

Dude (dude uncomplicated data extraction) is a very simple framework for writing web scrapers using Python decorators. The design, inspired by Flask, was to easily build a web scraper in just a few lines of code. Dude has an easy-to-learn syntax.

The simplest web scraper will look like this: ```python from dude import select

@select(css="a") def get_link(element): return {"url": element.get_attribute("href")} ```

dude supports multiple parser backends: - playwright
- lxml
- parsel - beautifulsoup - pyppeteer - selenium

Example Use


```javascript import { PlaywrightCrawler, Dataset } from 'crawlee'; // Create a crawler with Playwright for JS rendering const crawler = new PlaywrightCrawler({ // Limit concurrency to avoid overwhelming the target maxConcurrency: 5, // This function is called for each URL async requestHandler({ request, page, enqueueLinks }) { const title = await page.title(); // Extract data from the page const products = await page.$$eval('.product', (els) => els.map((el) => ({ name: el.querySelector('.name')?.textContent, price: el.querySelector('.price')?.textContent, })) ); // Store extracted data await Dataset.pushData({ url: request.url, title, products, }); // Follow links to crawl more pages await enqueueLinks({ globs: ['https://example.com/products/**'], }); }, }); // Start crawling await crawler.run(['https://example.com/products']); ```
```python from dude import select """ This example demonstrates how to use Parsel + async HTTPX To access an attribute, use: selector.attrib["href"] You can also access an attribute using the ::attr(name) pseudo-element, for example "a::attr(href)", then: selector.get() To get the text, use ::text pseudo-element, then: selector.get() """ @select(css="a.url", priority=2) async def result_url(selector): return {"url": selector.attrib["href"]} # Option to get url using ::attr(name) pseudo-element @select(css="a.url::attr(href)", priority=2) async def result_url2(selector): return {"url2": selector.get()} @select(css=".title::text", priority=1) async def result_title(selector): return {"title": selector.get()} @select(css=".description::text", priority=0) async def result_description(selector): return {"description": selector.get()} if __name__ == "__main__": import dude dude.run(urls=["https://dude.ron.sh"], parser="parsel") ```
