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 desktop 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.

Key Features

• The Accretion desktop — a live black-hole scene with your apps in orbit, three modes (Server, Personal, Cluster) with three spaces each, a dock, a command palette (Ctrl/⌘+K), floating Molly and Terminal windows, synced appearance (four accents or your own, light/dark, three motion levels, sounds) and a new first-run setup. New in 0.11.0. Tour the desktop.
• Four languages (new in 0.12.0) — English, Русский, Español and Français, switched live in Settings → Appearance → Language. Errors, notifications and Molly’s replies follow your language. Languages
• Choose your components (new in 0.11.2) — the installer asks which parts you need (S3 storage, VPN, local AI, mail, WhatsApp, system tuning, network management, Docker). Skipped parts stay hidden, and you can add or remove them later in Settings → Components or with sudo quazzar setup. Components
• S3 storage on Garage (new in 0.12.1) — S3 Object Storage installs Garage, access keys get per-bucket read/write/owner access, and MinIO nodes move their data over automatically. Object Storage
• Launchpad — 115+ app templates (databases, media servers, dev tools and more) and every installed app in one place. Launchpad
• Family — parental controls and classroom management for Linux devices: live timeline of programs and DNS queries, URL/app blocklists, bedtime + screen-time budget, live screen view (Pro), and bulk policy push for groups of student devices (Pro). See the setup guide.
• First-class Plex support — one-click install (Docker or SystemD), detection of existing installs, live stats dashboard, optional Quazzar SSO front-door. Available on every plan.
• Overview, Home and widget boards — a Server Overview with live CPU, memory, disk and network, a Molly insight and a live event timeline; a Personal Home with weather, agenda, to-dos, now playing, recent notes and Drive usage; below both, a free-form widget board. Your layouts and hero blocks sync to your profile. Since 0.9.7: per-user layouts sync server-side across devices, the Network widget shows per-interface RX/TX history with a range picker, Storage Overview detects all real filesystems, and Service Status paginates with a running/all filter
• Orbit productivity suite — Docs, Sheets, Slides, and Notes — canvas editors with Markdown round-trip, 80 formulas, 5 chart types, 7 slide layouts, and optional CRDT collaboration (Orbit Pro)
• Memory MCP — built-in MCP server that exposes your notes as durable memory for Claude Desktop, Claude Code, ChatGPT, Cursor, and VS Code Copilot. Free on every plan
• Cross-node memory sync — opt-in per-namespace replication between multiple Quazzar nodes via the Control Panel (Orbit Pro)
• Tickets & Kanban — built-in work tracker with a Kanban board, wiki-linkable from Molly memories and Notes
• Domains & Routes Manager — route any subdomain or full domain to an installed app, the OS UI, or a manual host:port; optional per-route Quazzar SSO gate; built-in port-conflict resolution for nginx/Apache coexistence
• Automatic HTTPS — embedded Caddy reverse proxy with Let’s Encrypt certificate provisioning
• Encrypted Backups — scheduled backups to local storage, S3, or SFTP with AES-256-GCM encryption
• Time-Series Monitoring — per-app container stats with automatic data rollups for long-term history
• VPN Management — WireGuard kernel integration and Pritunl Docker-based VPN with peer management
• Security Scoring — Trivy CVE scanning, WAF with Coraza/OWASP rules, CIS Docker Benchmark compliance
• Multi-User RBAC — Admin, Operator, and Viewer roles with TOTP 2FA and audit logging
• Passkeys & lock screen (new in 0.11.0) — sign in with Face ID, Touch ID, Windows Hello or a security key, approve a sign-in from your phone, and lock your session without logging out. See Sign-in & Lock Screen
• AI Hub — local LLMs via Ollama/LocalAI, cloud LLM gateway, RAG knowledge base, agent builder, Molly assistant with memory injection
• Cluster mode (working in 0.11.0) — create a cluster, join machines with quazzar cluster join and approve them; nodes connect over WireGuard automatically. The Constellation, Nodes and Placement spaces show the fleet live, node labels pin apps, and apps restart on a healthy node when a worker fails. Clustering
