Getting out of my comfort zone here, as I feel we are not ready, but my company is working on a product that is focusing much more on application profiling than NewRelic and less on the monitoring that is built exclusively for PHP:

We are still in closed beta but not for long anymore. You can sign up for our waiting list if you are interested to hear more.

As for the pricing, we are working on a model that is not per server/host.
