IIRC regular cloudflare will still cache assets for free. This tool is specifically for people who don't want to write a pipeline to do image resizing/optimization themselves. If you're able to write your own pipeline to do sprite sheets, you probably don't need this service to begin with. Just preprocess everything yourself and serve those at $0 per gb.
Yes, that makes sense. But it is interesting that this product becomes crazy expensive as the image size gets smaller. $1 per 100,000 served images is a weird pricing model unless you're serving exclusively large images.
This is true but remember, we also have volume pricing. If you're storing tens of millions of images or delivering hundreds of millions of images, talk to us :)
