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.
php-spider is a PHP library for web crawling and scraping. It allows developers to easily navigate and extract data from websites by simulating a web browser's behavior.
- supports two traversal algorithms: breadth-first and depth-first
- supports crawl depth limiting, queue size limiting and max downloads limiting
- supports adding custom URI discovery logic, based on XPath, CSS selectors, or plain old PHP
- comes with a useful set of URI filters, such as Domain limiting
- supports custom URI filters, both prefetch (URI) and postfetch (Resource content)
- supports custom request handling logic
- supports Basic, Digest and NTLM HTTP authentication. See example.
- comes with a useful set of persistence handlers (memory, file)
- supports custom persistence handlers
- collects statistics about the crawl for reporting
- dispatches useful events, allowing developers to add even more custom behavior
- supports a politeness policy
This Spider does not support Javascript.

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']);
```
```php
use Example\StatsHandler;
use VDB\Spider\Discoverer\XPathExpressionDiscoverer;
use Symfony\Contracts\EventDispatcher\Event;
use VDB\Spider\Event\SpiderEvents;
use VDB\Spider\Spider;
require_once('example_complex_bootstrap.php');
// Create Spider
$spider = new Spider('http://dmoztools.net');
// Add a URI discoverer. Without it, the spider does nothing. In this case, we want tags from a certain
$spider->getDiscovererSet()->set(new XPathExpressionDiscoverer("//div[@id='catalogs']//a"));
// Set some sane options for this example. In this case, we only get the first 10 items from the start page.
$spider->getDiscovererSet()->maxDepth = 1;
$spider->getQueueManager()->maxQueueSize = 10;
// Let's add something to enable us to stop the script
$spider->getDispatcher()->addListener(
SpiderEvents::SPIDER_CRAWL_USER_STOPPED,
function (Event $event) {
echo "\nCrawl aborted by user.\n";
exit();
}
);
// Add a listener to collect stats to the Spider and the QueueMananger.
// There are more components that dispatch events you can use.
$statsHandler = new StatsHandler();
$spider->getQueueManager()->getDispatcher()->addSubscriber($statsHandler);
$spider->getDispatcher()->addSubscriber($statsHandler);
// Execute crawl
$spider->crawl();
// Build a report
echo "\n ENQUEUED: " . count($statsHandler->getQueued());
echo "\n SKIPPED: " . count($statsHandler->getFiltered());
echo "\n FAILED: " . count($statsHandler->getFailed());
echo "\n PERSISTED: " . count($statsHandler->getPersisted());
// Finally we could do some processing on the downloaded resources
// In this example, we will echo the title of all resources
echo "\n\nDOWNLOADED RESOURCES: ";
foreach ($spider->getDownloader()->getPersistenceHandler() as $resource) {
echo "\n - " . $resource->getCrawler()->filterXpath('//title')->text();
}
