Made in Germany.
Built like Silicon Valley.
Digital products & software systems
From consumer platforms to developer tools — built to perform in the real world.
Selected work
We build systems, not just apps
Every project ships to production. Real users, real traffic, real constraints.
DIGI
Open Source
From empty VPS to production with TLS in under 60 seconds. Zero-config deployment for Bun and Astro apps — compiled daemon, blue-green deploys, no vendor lock-in.

Upstream contributions
We build the infrastructure we need and upstream everything we can. Astro adapters, nixpkgs packages, framework bug fixes — real contributions to the tools we depend on.

Two products, one standard
Developer infrastructure and consumer platforms — built with the same principles, the same urgency.
Engineering
When the stack breaks, we fix it upstream.
Active maintainer and contributor at the framework and infrastructure level. Not drive-by — real fixes from production work.
About
Solo-founded.
Fully bootstrapped.
Scaliir Digital is a one-person engineering company based in Frankfurt, Germany. We design, build, and operate production systems — from real-time consumer platforms to open-source developer infrastructure.
No investors, no committees, no bloat. Every line of code, every architecture decision, every deployment — one person, full accountability.
Work with us
We work on a small number
of selected projects
