I looked through the pages... Tried a few times to find out what happens if I decide to use your tool after the 24H. I looked for a pricing page and failed. Makes sense if this is just your POC/demo.
So yeah, the ambiguity of all this makes it highly unattractive to even evaluate. It doesn't offer any value that a terraform RDS script or even docker-compose script that renders a template to give you the copypasta database init blocks.
