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,[3] 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.[4]

Some well-known companies and products using Scrapy are: Lyst,[5][6] Parse.ly,[7] Sayone Technologies,[8] Sciences Po Medialab,[9] Data.gov.uk’s World Government Data site.[10]

History

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.[11] In 2011, Zyte (formerly Scrapinghub) became the new official maintainer.[12][13]
