I built out https://file-crocodile.io in two weeks. I've used a Vue.js frontend with a full Microsoft Azure stack for the back end.
It's come together really nicely and works as I want it to. I've even managed to integrate cash and crypto payments - I thought crypto would be a good idea in order to offer a completely anonymous service!
Obviously, as an MVP I still need to tweak some things and run further tests (I'm pretty sure it doesn't work on Internet Explorer, for example), but please feel free to use the service - you will be able to use its small feature set absolutely free.
I welcome any feedback.
