Scrapy

Scrapy is the de facto standard Python web crawling and scraping framework. Where BeautifulSoup is a parsing library requiring manual orchestration, Scrapy is an opinionated framework with a spider architecture, middleware pipeline, item validation pipeline, and built-in concurrency and rate limiting.

Architecture

• Spider: A class with start_urls and a parse() method; Scrapy manages the request queue, deduplication, and async concurrency
• Item pipeline: Validated items flow through configurable pipeline stages — clean, validate, store — in sequence
• Middleware: Pluggable layers for user-agent rotation, proxy handling, retry logic, and cookie management
• Exports: Built-in JSON, CSV, and XML export; database storage via pipeline plugins
• scrapy-playwright: A plugin that adds JavaScript rendering to Scrapy spiders without abandoning the framework

Relationship to Data Contracts

Scrapy's Item and ItemLoader system is the natural integration point for Pydantic validation (see Data Contracts for Scraping Pipelines). Items validated through a Pydantic model in the pipeline surface schema drift immediately, combining Scrapy's crawl management with contract-enforced data quality.

Radar Assessment

Scrapy sits at Languages & Frameworks → Assess inner. It is a mature framework (10+ years, 52,000+ stars) proven at production scale. Inner position reflects minimal adoption friction (pip install scrapy, scrapy startproject), a comprehensive feature set that eliminates the manual wiring required with requests + BeautifulSoup, and direct complementarity with the Data Contracts for Scraping Pipelines blip already on the radar. The remaining gate before Trial is confirmed use as the scraping engine on at least one active project with a real crawl volume.
