I've been using Notifo for almost a year now (I think) and I always liked everything about it except the fact that it was free. I couldn't see how the company stands to make money without charging users.

So I always suspected this moment would come and I always wondered — why not simply charge people? I would have gladly paid, say, $20 a year — just for the limited amount of notifications I receive. It's a valuable service that appeals to an audience that values their time. Sure, you can hack your own notification system, but why bother if someone already did it for you?

I use Notifo with github, my monitoring systems, my backup systems and a bunch of other things. Again, charge me on the order of $20-$30 a year, and I'll pay.
