I think your pricing scheme[1] could put a lot of people off. I fall into the category where I'd be fine on the free tier (< 10 private services), and yet I don't want a free service.
I know if it's free, then it's going to be under some kind of fair usage policy, and you're going to rate limit me or have some kind of restrictions eventually. There's no way it can be sustainably free if I start to push it really hard. I'd prefer to just know the limits upfront, or have some kind of usage based pricing.
