About scrapy
Scrapy is a web scraping framework written in Python, distributed under the BSD 3 Clause license, and described in its own README as a tool to extract structured data from websites. It is cross platform and requires Python 3.10 or newer. The project is maintained by Zyte, formerly known as Scrapinghub, together with a broader group of contributors, and it lives in the Python ecosystem as an installable library rather than a hosted service. Its repository is roughly seventeen years old, which places it among the longer running projects in the web scraping space.
