When I use Selenium I can see the Browser GUI, is it somehow possible to do with scrapy or is scrapy strictly command line based?
Scrapy by itself does not control browsers. 
However, you could start a Selenium instance from a Scrapy crawler. Some people design their Scrapy crawler like this. They might process most pages only using Scrapy but fire Selenium to handle some of the pages they want to process.
Can scrapy control and show a browser like Selenium does?
