Your landing page at https://remote.storage/ is so good, I love the minimalism. Six lines of code tell me exactly what it does.
I like the minimalism too, but I don't think it tells me "exactly what it does". I have no idea from that page what the backend requirements are. Is it a hosted solution? Is it using some browser profile functionality? Do I have to set up a server?
It demonstrates the simplicity of the client side code for sure. But the server stack is obviously where the details are going to be.
