As answered by people managing RabbitMQ and Codelet Billing.
Codelet Billing's answer:
Indie hackers and small-to-medium teams requiring complex billing that isn't supported in Stripe or Paddle.
Codelet Billing's answer:
Codelet is built self-serve, with only a few API calls required to get set up. Agents can build full integrations in minutes. Codelet supports credit-based (prepaid) and usage-based (postpaid) billing on top of Stripe and Paddle, in any combination of pricing models, like graduated, flat-rate and stairstep. All in a simple platform that's quick and easy to set up and master.
Codelet Billing's answer:
Codelet is a drop-in API integration, which removes the complexity of a native billing system, and replaces with a few API calls. Pricing and billing can be managed from a simplified dashboard. Codelet runs on either Stripe or Paddle, giving flexibility for payments and Merchant of Record features.
