Linux & ARM First
We care about hardware constraints early. If a build behaves well on modest Linux and ARM targets, stronger machines are a bonus.
About Ghost Citadel
LINUX-FIRST STUDIO // GAMES · OBSERVATORY · SCRIPTORIUM · FORGE
Ghost Citadel builds interactive worlds, analytics engines, and applied engineering systems from the same technical foundation: Linux-first development, real telemetry, open standards, and software that must survive on real hardware.

From Tallinn With Voltage
Ghost Citadel was sketched in Tallinn, close to the industrial history of Soviet-era electronics and lunar exploration. The company is now incorporated in the United Kingdom and built around a European engineering mindset.
Our work connects game systems, data engines, hardware testing, and industrial software. The studio is small by design: fewer layers, clearer ownership, and stronger technical responsibility.
What We Build
Games
Playable Systems
Linux-first games where physics, input latency, cameras, and rendering are treated as engineering problems, not decoration.
ObservatoryProcess Truth
A process-mining product that turns enterprise event logs into decision-grade flow diagnostics on customer infrastructure.
ScriptoriumApplied Engineering
Selective custom work when the problem requires real implementation rather than generic dashboards or consulting theatre.
ForgeModels & Prototypes
The production space for assets, industrial imagination, experimental tools, and prototype systems.
Foundation
Systems + Story
We build worlds, engines, and analytics around systems that can be inspected, measured, and improved.
Open by Default
Open tools, clear exports, and explainable technical choices. Closed components must have a reason.
Evidence, Not Hype
Logs, profiles, benchmarks, and test builds matter more than slogans. The work must prove itself.
