It's made for designers, developers, docs writers who share lots of screenshots. Simply drop the photo and it'll be styled automatically to give a good look quickly.
You can also achieve whatever look & style you wish by editing photo with lots of available options.
I made it for myself when i was working on my portfolio. I wanted to showcase my work. None of available options hit me quite right.
all of them pushed a subscription in one way or another, so i decided to build one myself. there are no subscription or popup asking for subscription or email in moocup , EVER.
for that reason, i made moocup open-source. so i can put it in good shape and make it's future better.
i use many of the tools made by very nice people that are completely free, this is my way of giving back.
