Honestly, I don't know. I think WakaTime is great (based on what I've read), and it does time tracking which Code::Stats does not do (and probably will not do). Other than that, I don't really know its features because I've never used it, so I don't think in terms of how to compete with WakaTime. I just think of things that I'd like to see in my own service. I know people who use both, and why not?

Code::Stats started as my own version of an old site called Codeivate that had a similar XP based tracking system. Codeivate disappeared from the web completely for unknown reasons, so I launched my own because I liked the idea.

As for future ideas, one of the more requested things is user groups that would have combined statistics and internal leaderboards (with heavy disclaimers), so I'm definitely doing that at some point. I'd also like to do more gamification side things, like badges for reaching certain levels in languages. As a third, I want to look into monthly/annual reports that could be emailed.

If you have ideas, I'd love to hear them. :)
