I think the value-add with this service is the notification sending just by exposing an endpoint. I don't see any mention of not needing backend infrastructure (they even call out "connect your web service").
I think this is aimed at people who already are or can expose data via an HTTP endpoint and want notifications when that changes/updates. This includes the wide array of software developers who work on large OS projects that support sending notifications via services like PushBullet/Pushover/etc. Also, presumably, web services would just add a new endpoint with some auth token to easily send push notifications to their users without managing an app and everything else needed (push tokens, certs, GCM/FCM, apns, it can be a headache, trust me).
Personally I see pushover-type services (I use pushover so I'm only speaking from that experience) as more useful since I can "push" out of my networks much easier than a service can "poll" me. That said pushover has always been a little clunky IMHO with trying to get a service to send me notifications. So a simple "Paste this url into the refl.me app to get notifications from us" is a pretty attractive alternative for certain use cases.
