Kornio — Digital Products & Software Marketplace
A storefront built rather than rented from a third-party marketplace: try any product free with no account, then one payment unlocks it for life — no subscriptions, ever.
- No-account trials and samples on every product, unlocked instantly
- One-time PayPal payment — no subscriptions or renewals
- Paid files encrypted at rest, released only after verified payment
- Instant delivery: private download link and license key on-screen and by email
Built with the same expertise we offer as a service: SaaS & Cloud Platforms → · Delivered to clients under escrow protection.
Kornio started as a way to sell our own desktop software without giving a third-party marketplace a cut of every sale. It has since grown into a general storefront for digital products: printable learning packs and workbooks, icon and sticker bundles, offline web apps, developer starter kits, and Windows software, each with a free trial or sample a visitor can grab with no account and no email.
The engineering that matters happens around the payment, not the storefront: paid files are encrypted at rest and released only once PayPal confirms the charge, delivery is instant — a private download link and, for software, a license key, both on-screen and in the inbox the moment payment clears — and every payment route is idempotent so a network retry can never double-charge a customer or double-issue a file. It's the same payment-integrity and admin-dashboard thinking we bring to [SaaS and cloud platform](/services/saas-and-cloud-platforms) projects for clients, including [invoicing software](/portfolio/invoex) listed through it.
