@maskaravivek We can also consider https://codebeat.co/ it is free for open source.

Currently I don't pay that much attention to Codacy - it seems to only flag up false positives, which is annoying for reviewing PRs as Github's red 'x' icon could mean Travis has passed and Codacy is being weird about something minor. Also Codacy seems to sometimes get 'stuck' reviewing PRs, or fails it on Github but doesn't show the issues on Codacy to be fixed.

Therefore I'd be very up for swapping to something better.
