Scrapy (/ˈskrpi/ SKRAY-pee)[2] is a free and open-source web-crawling framework written in Python. Originally designed for web scraping, it can also be used to extract data using APIs or as a general-purpose web crawler.[3] It is currently maintained by Scrapinghub Ltd., a web-scraping development and services company.

Scrapy project architecture is built around "spiders", which are self-contained crawlers that are given a set of instructions. Following the spirit of other don't repeat yourself frameworks, such as Django,[4] it makes it easier to build and scale large crawling projects by allowing developers to reuse their code. Scrapy also provides a web-crawling shell, which can be used by developers to test their assumptions on a site’s behavior.[5]

Some well-known companies and products using Scrapy are: Lyst,[6] CareerBuilder,[7] Parse.ly,[8] Sayone Technologies[9], Sciences Po Medialab,[10] Data.gov.uk’s World Government Data site.[11][1]

History[edit]

Scrapy was born at London-based web-aggregation and e-commerce company Mydeco, where it was developed and maintained by employees of Mydeco and Insophia (a web-consulting company based in Montevideo, Uruguay). The first public release was in August 2008 under the BSD license, with a milestone 1.0 release happening in June 2015.[12] In 2011, Scrapinghub became the new official maintainer.[13][14]
