Hey Michael, We only store the differences between subsequent saves so the actual impact on bandwidth & storage is pretty small. We're still playing around with pricing but there will be a free tier with more options depending on the space used.
Thanks for the reply Shravan, that's awesome to know. Definitely sounds very promising, I'm looking forward to seeing the subscription plans when yous are ready.
Are the full files for each revision saved? Or have you developed a way to store only the differences?
With large PSD files, the former could get expensive quickly, which makes me wonder the same thing as ARolek asked, what will pricing be based on?
