SCRAPY
MEDIUM RISK📊 SEO & DATA SCRAPERPython web scraping framework — the most popular open-source scraping tool
📡 SCRAPY USER-AGENT STRING
Scrapy/2.11 (+https://scrapy.org)
This is the User-Agent header sent by Scrapy in HTTP requests. Use this to identify Scrapy in your server access logs.
📋 ABOUT SCRAPY
Scrapy is the most widely-used open-source web scraping framework, written in Python. It provides a complete toolkit for extracting structured data from websites, including built-in support for following links, handling pagination, managing request queues, and exporting data in various formats. Scrapy is used by thousands of companies and individuals for legitimate data collection.
By default, Scrapy identifies itself in the User-Agent header and respects robots.txt directives. However, these settings are easily configurable, and many Scrapy operators customize the User-Agent to mimic regular browsers or other bots. Scrapy does not render JavaScript by default, though integration with Splash or Playwright can add rendering capabilities.
NORAD.io monitors Scrapy-based crawling activity and classifies it as medium risk due to the ease with which Scrapy can be configured for aggressive scraping. NORAD's behavioral analysis can identify Scrapy-like crawl patterns even when the User-Agent is spoofed, using signals like request timing, crawl depth patterns, and content access sequences.
🎯 HOW TO DETECT SCRAPY
- ▸Default User-Agent starts with 'Scrapy/' — easily changed by operators
- ▸Scrapy respects robots.txt by default but this is configurable
- ▸Look for systematic crawl patterns: depth-first or breadth-first across site sections
- ▸Default concurrent requests: 16 — can create noticeable traffic patterns
- ▸Often runs from cloud servers (AWS, DigitalOcean, etc.)
🔄 CRAWL BEHAVIOR
Highly configurable crawl behavior. Default configuration is polite with auto-throttling, but operators can set aggressive rates. Supports concurrent requests, crawl depth limits, and custom middleware. Does not render JavaScript by default.
General-purpose web scraping framework used for data extraction, research, price monitoring, content aggregation, and competitive intelligence. Used by individuals, companies, and researchers.
🤖 ROBOTS.TXT CONFIGURATION
User-agent: Scrapy Disallow: / # Scrapy respects ROBOTSTXT_OBEY setting (default: True) # But operators can disable this in their configuration
Scrapy respects robots.txt directives. Add this to your robots.txt file at the root of your domain.
