Hi HN, I’m building Kite, a lean checkout layer for selling digital goods globally without coupons or regional pricing tables. The problem I kept hitting as a creator: global customers constantly ask for discounts, but existing tools either lock you into a marketplace or make PPP pricing manual and leaky. How it works Buyer’s country is detected at the edge (Vercel GeoIP) A PPP multiplier (World Bank data) is applied atomically at checkout The final price is locked server-side (no client overrides) Stack Next.js 15 (App Router + Server Actions) Supabase (Auth, Postgres, private buckets) Stripe Connect (Direct Charges – seller stays merchant of record) Delivery & security Digital files live in private Supabase buckets. After a successful Stripe webhook, we issue a 60s signed download URL, which avoids hotlinking and bandwidth abuse. Business model 5% flat fee per transaction. No marketplace, no customer data lock-in — sellers use their own Stripe accounts. I’d love feedback on: Whether PPP-based pricing feels intuitive or surprising as a buyer The UX tradeoffs of an embeddable checkout vs hosted pages I’m still unsure how aggressive the PPP multipliers should be without hurting perceived value.
