ADR-010: Billing via Polar, Donations via Ko-fi

  • Status: Accepted
  • Date: 2026-02-04

Context​

We want subscriptions with minimal operational overhead and a simple path for donations.

Decision​

  • Use Polar for subscriptions.
  • Use Ko-fi for donation links.

Consequences​

  • Quotas must integrate with subscription status.
  • Use Polar's Hono Adapter
  • Donations remain out-of-band (no entitlement changes implied).

Alternatives considered​

  • Stripe direct: flexible but higher implementation + compliance burden.
