import { Polar } from '@polar-sh/sdk';
import { Resend } from 'resend';
const polar = new Polar({ accessToken: process.env.POLAR_ACCESS_TOKEN });
const resend = new Resend(process.env.RESEND_API_KEY);
// Polar.sh Merchant of Record (MoR) automated subscription & checkout session
export async function createCheckout(customerEmail: string, productId: string) {
  const checkout = await polar.checkouts.custom.create({
    productId,

Site & Project Monetisation Models

Monetising developer software tools, SaaS products, and open-source packages requires choosing between Merchant of Record platforms, direct payment gateways, and usage-based billing.

  • Merchant of Record (MoR) vs Direct Gateway: An MoR (such as Polar.sh) acts as the legal reseller, assuming all worldwide tax liabilities (EU VAT, US sales tax) so developers don't have to register across dozens of jurisdictions.
  • Tiered Pro Paywalls: Protect premium server endpoints and client features with cryptographic session entitlements.
  • Usage Metering: Bill consumers precisely for compute or API calls using Redis atomic counters synced to billing webhooks.
