I just spent a day trialling Chartbeat, which is a very slick, paid real-time stats service, and then removed it because the differences over what Piwik and Google Analytics give me simply wasn’t enough to justify paying.
Eye-candy aside, there are some nice features to Chartbeat that I’d love to see in Piwik:
[ol]
[li] A dashboard widget showing how many people are on my site right now
[/li][li] A dashboard widget for social mentions, aimed at twitter & facebook at least
[/li][li] Email/sms alerts based on site traffic (although their current incarnation is mostly aimed at telling you that you’re going to need to change payment plans soon)
[/li][/ol]
One surprise was that Chartbeat saw more visitors than Piwik does in real-time, but when visitors seen by both appeared first in Piwik’s dashboard. Is this only because, of 2 pieces of code included on each page, Chartbeat has one piece of code at the top of each page?
