Keeping an eye on parse-hosting.com they have the most details about their plans and pricing so far. Do you have some more information? The landing is not informative at all. Would be interested to know what are you doing to offer.
Sad that Facebook pulled the plug on this. They owned it for so long it is hard to imagine that it was an acquihire. Good luck to the Parse team. I am sure Adam and people like him can help users migrate away smoothly.
We almost used Parse on a huge project recently. My thoughts go out to anyone who needs to consider migrating. This service looks like a good solution.
