Thanks! Really glad to hear that you're excited about it. The engines are meant to replace our existing analysis, and all of the engines we are running on codeclimate.com are now Open Source. That being said, we are indeed working on Brakeman and Flog engines, which should be available soon. As to the secret sauce behind our duplication analysis - you'll be able to see that soon! Stay tuned!
