Sovereign across
every cloud.
A railway signal box — a Stellwerk — keeps every train on the right track. Stellwerk does the same for multi-cloud: a sovereignty layer under your governance that routes workloads across every cloud you run — and refuses the routes that break your rules. Self-hosted by default. No phone-home.
The signal box for everything you ship.
Developers describe what they need in one portable workload spec. Stellwerk resolves it per environment, applies it through your existing infrastructure-as-code, and refuses any route that breaks policy — in the open, with the rule that stopped it.
-
Self-hosted by default
No managed control plane. Nothing phones home.
-
Policy at the boundary
Unsafe routes are refused before they reach a cloud.
-
We are your exit strategy
Every dependency Stellwerk resolves stays as portable IaC you own — walk away any time and keep everything running.
From first course to critical infrastructure.
The orchestrator is open source and stays that way — EUPL, no proprietary code, ever. What we offer is everything that makes it carry production: knowledge, operation, early security, and support. Five offerings, one route.
