Localstack Pro looks quite nice and comprehensive, but the CI pricing seems to really discourage proper continuous integration best practices. At 10 cents per run you're encouraging developers to run their CI pipelines as little as possible, while ideally you'd run CI on each commit and you'd commit often, probably 10s is times a day. In that case Localstack Pro for CI would get costly very quickly.

Why not have CI pricing per project/repo. Regardless of how often it runs.
