This comment encapsulates the inspiration behind Kable beautifully.

Developers I've spoken with have struggled to get up and running with AWS API Gateway or GCP Endpoints. They each had plans to evolve their pricing model based on business-specific metrics (like monthly active users, transactions processed, or requests to specific APIs), and they weren't able to get the per-contract or per-endpoint pricing flexibility out of these offerings that they wanted.

Kable's greatest strength is its usage metering and billing. Not every developer is going to need to outsource their entire API gateway, and that's alright. In the early days, this does help get to market faster. At scale, though, when billing becomes more and more complex, is where Kable's greatest strengths in billing shine.
