Comments and Reviews
Said about Scrapy as an alternative
All the infrastructure bits that come with it if you need. Its pretty much impossible to do a significant crawl all by yourself (proxy management hell), so being able to get things working first and then lean on the backend infrastructure the scrapy guys have is a major relief.
Requires lots of development to make it work. Has certain limitations when it comes to markup detection on a moderns sites.
Like ParseHub, Scrapy allows users to construct and run web scrapes. Unlike ParseHub, Scrapy is command-prompt based and has no GUI.
