Whilst this looks like a well-polished and usable product I think $30 as the cheapest price plan is maybe slightly too much considering the current feature set.

I don't know how server-intensive and costly this is to run, but as Redis is free software I think your prices are maybe 25-50% too much. For $30 I'd expect maybe email or SMS notifications when spikes occur, for just one example.
