I am a developer too needing a API, I currently use Affinity at home.
Now I was looking for a Illustrator and Corel replacement for work as I also develop in-house applications for our production line with about 500+ computers attached to a machine, currently running Corel DRAW or Illustrator. The CorelDRAW API is much better and you can do almost anything but the output sucks. The Illustrator API is a little limited and harder to use but output is super.
I basicly automate and creat interfaces that go on top of CorelDRAW or Illustrator's API that integrate in our manufacturing enviroment and controll the machine. Reading that Affinity currently does not have this kind of API is a stopper for us and it looks like we have to stick with Illustrator and Corel for awhile.
