Paying for it
As with all great services, there is a
price to pay for
using CodeClimate (with private projects).
Its easy to fall into the trap of thinking
$99 per month is "expensive"... But I suggest you
Think of CodeClimate as a member of your team who's job is to
code-review and alert people when code gets better or worse.

If you're still having trouble convincing your "boss"
that $99 per month is cheap for a "second pair of eyes" on your code,
try it (free) for your personal (open source) GitHub projects
learn what code quality looks like and then try again.
