# OUDENIC

> Data without borders.

OUDENIC is a cross-border connectivity infrastructure provider. We sell instant-activation eSIM data plans worldwide. No app download required - buy a plan on the web, receive a QR code in seconds, scan it, and connect.

We operate on a zero-inventory model: eSIM profiles are provisioned on-demand from upstream suppliers at purchase time. All prices are in USD. The platform is built with Rust and Next.js, runs on SQLite, and uses Beancount for automated plain-text accounting.

OUDENIC is not a lifestyle brand. We are infrastructure - quiet, reliable, and minimal. No gamification, no referral schemes, no dark patterns. Just connectivity.
