Botasaurus is an all-in-one Python web scraping framework that combines browser automation, anti-detection, and scaling features into a single package. It aims to simplify the entire web scraping workflow from development to deployment.
Key features include:
- Anti-detect browser Ships with a stealth-patched browser that passes common bot detection tests. Automatically handles fingerprinting, user agent rotation, and other anti-detection measures.
- Decorator-based API Uses Python decorators (@browser, @request) to define scraping tasks, making code clean and easy to organize.
- Built-in parallelism Easy parallel execution of scraping tasks across multiple browser instances with configurable concurrency.
- Caching Built-in caching layer to avoid re-scraping pages during development and debugging.
- Profile persistence Can save and reuse browser profiles (cookies, localStorage) across scraping sessions for maintaining login state.
- Output handling Automatic output to JSON, CSV, or custom formats with built-in data filtering.
- Web dashboard Includes a web UI for monitoring scraping progress, viewing results, and managing tasks.
Botasaurus is designed for developers who want a batteries-included framework that handles anti-detection automatically, without needing to manually configure stealth settings or manage browser fingerprints.
Scrapy is an open-source Python library for web scraping. It allows developers to extract structured data from websites using a simple and consistent interface.
Scrapy provides:
- A built-in way to follow links and extract data from multiple pages (crawling)
- Handling common web scraping tasks such as logging in, handling cookies, and handling redirects.
Scrapy is built on top of the Twisted networking engine, which provides a non-blocking way to handle multiple requests at the same time, allowing Scrapy to efficiently scrape large websites.
It also comes with a built-in mechanism for handling common web scraping problems, such as:
- handling HTTP errors
- handling broken links
Scrapy also provide these features:
- Support for storing scraped data in various formats, such as CSV, JSON, and XML.
- Built-in support for selecting and extracting data using XPath or CSS selectors (through
parsel). - Built-in support for handling common web scraping problems (like deduplication and url filtering).
- Ability to easily extend its functionality using middlewares.
- Ability to easily extend output processing using pipelines.
