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
Kimurai is a modern web scraping framework for Ruby, inspired by Python's Scrapy. It provides a structured approach to building web scrapers with built-in support for multiple browser engines, session management, and data pipelines.
Key features include:
- Multiple engine support Can use different backends depending on the scraping needs: Mechanize for simple HTTP requests, Selenium with headless Chrome/Firefox for JavaScript-rendered pages, and Poltergeist (PhantomJS) for lightweight rendering.
- Scrapy-like architecture Follows the spider pattern: define a spider class with start URLs and parsing methods, and the framework handles crawling, scheduling, and data collection.
- Built-in data pipelines Save scraped data to JSON, CSV, or custom formats with configurable output pipelines.
- Session management Maintains browser sessions with automatic cookie handling and configurable delays between requests.
- Request scheduling Built-in request queue with configurable concurrency, delays, and retry logic.
- CLI tools Command-line tools for generating new spiders, running individual spiders, and managing scraping projects.
Kimurai is the closest Ruby equivalent to Scrapy. It's well-suited for structured scraping projects that need organization, multiple spiders, and data pipeline processing.
Note: Kimurai has not seen active development recently, but it remains a useful framework for Ruby scraping projects and is included as the most complete Ruby scraping framework available.
