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
