The idea for supporting any commit on the whole repo is interesting (and honestly, not hard to implement), definitely see the benefit there!
Re: mobile. Yeah, maybe we could push arbitrary assets to a bucket somewhere so that you could serve an android build there. We're definitely focused on the web aspect, but this is exciting wrt/ making Reploy more encompassing.
And re: pricing. Got it. If you don't mind sharing more about your team's situation, we can probably figure something out (my email's in the post). The reason we charge per seat is because its a reasonable proxy for how many environments are being spun up, and frankly we're still learning how to metricize. It'd be cool to see what your team's workflows look like.
