Improve this question

I came across https://codeclimate.com. Super awesome, but I'm working on a project whose code I cannot share with others or Code Climate.

Now I would like to be able to improve my code quality and wonder if anyone can suggest tools that do what codeclimate.com does but locally in development mode, without me having to share my code.

Answer 1

The metric_fu gem seems to be the best option combining all known test tools into 1 an generate a neat report although its not as nice and fully featured as code climate.com

Answer 2

We can use Fog gem which give code complexity at class and method level. To check code duplications we can use Flay gem.

Both give same result that code climate gives.

Answer 3

Now there's an exact answer: Last year Code Climate released a new platform which includes a command-line interface, Code Climate CLI. It runs entirely on your computer (in a Docker container) and doesn't require a Code Climate account.
