I like how easy it was for me as an amateur developer (and non-technical person)to get my app up & running with api flash in under 30 minutes! The documentation could be better - some things were unclear or not well explained at first glance.- Not sure if this has been mentioned elsewhere but there are no free trial accounts available so you have nothing else compare against when deciding whether its worth your while paying $99/monthly-$499 annually vs using something cheaper / more open source such as Cloudinary etc..
Also dont expect too much from support other then 1x ticket response time which seems rather slow compared even what i would consider normal email responses times here where im located!! We needed another service we had used previously closed down by them without warning us about any sortof notice period before they shut off our account completely leaving everything behind including client data stored within cloudflare.
