Given that pagefair does this for free and already has whitelisting agreements with adblock lists, I think your pricing is too high. The only differences I see at a glance are that you break it down into per-device stats and have a tabular view.

Does your javascript snippet support subresource integrity? That would be a key selling point as pagefair's CDN was hacked and their snippet replaced to do malware redirects against users. After that incident I'm keeping the number of scripts from "startups" to an absolute minimum.
