What is Cloudron? A Complete Overview

Cloudron is a platform that makes it easy to run and manage web applications on your own server. It gives a unified interface for installing, updating, and maintaining a wide variety of open-source and commercial apps, handling all the technical details such as DNS setup, SSL certificates, backups, and user management.

Core Architecture

To understand how Cloudron operates, it is vital to know that Cloudron is an all-or-nothing platform.

Unlike standard development panels that install as lightweight software tools, Cloudron acts as a total server orchestrator. It requires a completely fresh, dedicated installation of Ubuntu LTS and assumes full root-level control over the operating system, network firewalls, and data paths.

• Complete Container Isolation: Every application runs in its own Docker container, ensuring that apps are fully isolated from each other for security and stability. This prevents one app from interfering with another and limits the impact of vulnerabilities.
• Decoupled App State: Application data and configuration are separated from the app runtime, making upgrades, backups, and restores seamless and reliable.
• Centralized Database Services: Cloudron manages databases centrally, providing each app with its own managed database instance (such as MySQL, PostgreSQL, or MongoDB) and handling credentials, backups, and updates automatically.

Key Features

• One-Click App Installation: Deploy popular apps like WordPress, Nextcloud, GitLab, Rocket.Chat, and more with a single click.
• Automated Updates: Keep apps and the platform itself up to date with minimal effort.
• Centralized Dashboard: Manage all your apps, users, and domains from a single, intuitive web interface.
• Multi-Domain Support: Easily host apps on multiple domains and subdomains.
• App Isolation: Each app runs in its own container for security and stability.
• LDAP & SSO Integration: Built-in user directory and single sign-on for all apps.

App Store and Deployment

• Cloudron App Store: Access a curated library of over 100 ready-to-deploy applications.
• Custom App Support: Install your own custom or private apps using Cloudron’s packaging system.
• Automated DNS & SSL: Cloudron configures DNS records and issues SSL certificates automatically for each app.
• Resource Management: Monitor CPU, memory, and disk usage for each app from the dashboard.
• Easy Migration: Move apps between servers or providers with built-in backup and restore tools.

User and Domain Management

• User Roles: Assign admin, user, or app-specific roles for granular access control.
• Single Sign-On (SSO): Users log in once to access all apps they’re permitted to use.
• Multi-Domain Management: Add and manage multiple domains and subdomains.
• Email Server Integration: Built-in mail server for app notifications and custom domains.

Security and Backups

• Automated Backups: Schedule regular backups for all apps and system data, with support for remote storage (S3, SSH, etc.).
• SSL Certificates: Free, automated SSL for all apps using Let’s Encrypt.
• App Isolation: Every app runs in a secure container, limiting the impact of vulnerabilities.
• Access Controls: Fine-grained permissions for users and groups.
• Audit Logs: Track user actions and system events for compliance and troubleshooting.

Technical Feature Breakdown

• Automated DNS, SSL, and HTTP/3: Automatically controls DNS records, issues, and renews SSL certificates, and supports modern web protocols like HTTP/3 for all hosted apps, ensuring secure and fast connections without manual intervention.
• Centralized User Directories (LDAP & SSO): All user authentication is managed centrally via LDAP, enabling single sign-on across all apps and simplifying user management for organizations.
• Disaster Recovery and Automated Backups: Cloudron provides scheduled and on-demand backups for both apps and system data, with easy restore options to recover from failures or migrations. Backups can be stored locally or on remote storage providers for redundancy.
