All in a simple platform that's quick and easy to set up and master.

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.
