How the site is put together.

Set in

Headings are set in Source Serif 4 in its light weight, running text, navigation and labels in Hanken Grotesk. Figures in the sample tables use JetBrains Mono. All of it is served from our own domain, so loading a page contacts no font provider.

Built with

Next.js and React on the front, FastAPI and Postgres behind it, Redis for the queue. Everything runs in ordinary Docker containers.

Run on

Servers in Germany (EU). No analytics, no trackers, no consent banner.

The pictures

Every product view on this site is a drawing. The figures show how the system actually works, with sample values in place of real ones. No customer data appears anywhere on these pages.

The company

Korydian Labs Ltd., registered in Malta under C115846. Address, representation and VAT number are in the imprint.
