About Clear The Sky

Self-hosted IT for small companies and government bodies

Clear The Sky helps organisations take control of their digital infrastructure. We design, build, and maintain self-hosted platforms that give you full ownership of your data — without depending on big cloud providers.

What we do

  • Private cloud — File storage, calendar, contacts, and document editing (Nextcloud)
  • Email — Self-hosted email with your own domain (Stalwart)
  • Code hosting — Git repositories, CI/CD pipelines, and container registries (Gitea, Tekton, Harbor)
  • Identity management — Single sign-on across all your applications (Keycloak)
  • Monitoring — Dashboards, metrics, logs, and alerts (Grafana, Prometheus, Loki)
  • Password management — Team password vault (Vaultwarden)

How we work

Everything runs on Kubernetes (K3s) with GitOps (ArgoCD), meaning every change is version-controlled and reproducible. Your infrastructure is defined as code, auditable, and recoverable from scratch.

We use only open-source software. No vendor lock-in, no licensing surprises, no data leaving your premises unless you choose to.

Who we serve

Our clients are small companies and government bodies in the Netherlands who want:

  • Full data sovereignty — your data stays on your hardware
  • Compliance with Dutch and EU regulations (AVG/GDPR)
  • Independence from US cloud providers
  • Transparent, reproducible infrastructure
