Cloud OS

Quazzar Cloud OS is a self-hosted server management platform that turns any Linux machine into a fully managed hosting environment. Built with a Go backend, React frontend, and SQLite database, it is distributed as a .deb package you install via APT.

What is Cloud OS?

Cloud OS provides a complete server control plane without the complexity of Kubernetes or manual Docker Compose workflows. You get a web dashboard with one-click app installs, automatic HTTPS, real-time monitoring, encrypted backups, VPN access, AI-powered tools, and multi-node clustering — all managed through a clean web interface.

It is designed for developers, small teams, and organizations who want to self-host applications with minimal operational overhead.
