Clixpy is a decent clone of clicktale.com, userfly.com, and exactostats.com, but doesn't seem to have a "shtick" that differentiates it from the other offerings. With userfly.com, we tried to make everything dead simple, and much cheaper than clicktale. We also focus on capturing quality user sessions (lots of page views, lots of actions fired per page, bounced users don't count against your quota).<p>However, at the end of the day, watching individual user sessions, one after another, doesn't really scale; you need a way to aggregate the data to identify trends that may suggest pain points for the end user, and we haven't really cracked that nut (and neither have our competitors).
