Drop‑in checkout. Minutes to integrate. Built to scale.

Ship a beautiful, production‑ready checkout without the heavy lift. Geins Checkout is an open‑source, drop‑in experience that runs on the Geins cloud‑native platform—tapping directly into Cart, Promotions and Orders so totals, taxes and discounts are always right.

    Drop‑in integration
    Add a full checkout to any storefront—or use it standalone. Reduce time‑to‑value from weeks to hours.
    Brandable UX
    Make it yours with flexible layouts and styles so checkout feels native to your brand.
    Promotions‑aware
    Built on Geins Promotions and Cart so stacking, eligibility and clean rounding just work.

Why a drop‑in checkout?

    Launch a best‑practice checkout in days, not sprints. Focus your team on differentiation, not infrastructure.
    Higher conversion
    A streamlined flow reduces friction and cart abandonment while keeping totals and promotions accurate.
    Built to experiment
    Own the code. Test copy, steps and visuals. Ship changes safely behind feature flags.
