What about checkout, can I keep Magento's checkout?
You have three options:
- Build native headless checkout, Most expensive ($3k, $15k extra). Full UX control. Required for B2B / multi-step / saved-quote flows.
- Hand off to Magento checkout via SSO, Cheapest. Cart on headless, “Checkout” button redirects to Magento Hyvä Checkout (or Luma). Ugly URL transition but works in days, not weeks.
- Embed Magento checkout in iframe, Don’t. SEO mess, payment-gateway PCI complications.
For most $7,999 builds we recommend hand-off to Hyvä Checkout, it’s already 1-page and <1s, which beats most custom headless checkouts. Build native only if you’re in the Enterprise tier.
