The best thing about stataticaly was that it solved my problem of not being able to use github or gitlab as cdn provider because I wanted to host all files in one place instead having multiple places where only some were hosted.
So this solves problems like if someone else has access to our repository they will be hosting everything there which we don't want them too - also since its free no worries! Not much actually but what i liked most was how easy the setup process was and especially how fast it got up an running compared to other services out there. Also their support team are very friendly and helpful through chat feature (which sometimes doesn't work though)And when something does go wrong they fix things quickly!
