Old, unloved and depricated.
Kimurai is no longer maintained. The car sites all updated their HTML so the scrapers no longer work. I'll create a new project to look for my next car
Carcrawler is a friendly webscraper I wrote to find the car I want for the best price.
It currently supports 4 car sites and stores the result in a Postgresql database. It uses Kimurai (https://github.com/vifreefly/kimuraframework) for the crawling.
OSX: brew cask install google-chrome brew cask install chromedriver
other: see https://github.com/vifreefly/kimuraframework
Results are stored in a database. I use Postgresql, but change Gemfile and database.yml if you want something else.
You do need to change the starting urls for each of the supported car sites to make it look for the car you want.
Crawler.crawl!
Start your Rails server:
rails s
http://localhost:3000 will serve up a nice chart
