OpenPanel

Overview

OpenPanel is an open-source web hosting control panel built around Docker containers. It gives every user a fully isolated environment with dedicated MySQL instances, configurable PHP versions (5.6 to 8.4), and support for multiple web servers including Nginx, Apache, and OpenLiteSpeed. Designed as a modern, affordable alternative to cPanel, it includes a two-panel architecture: OpenAdmin for server administrators and OpenPanel for end users. The Community Edition is free forever, while the Enterprise Edition adds white-labeling, billing integration, and priority support.

Key Features

Docker-Based User Isolation: Each user gets a fully containerized environment with their own MySQL, PHP, and caching services, providing VPS-like control without the complexity.
Multi-Web Server Support: Choose from Nginx, Apache, OpenLiteSpeed, OpenResty, or Varnish on a per-domain basis to match your performance needs.
Flexible PHP Management: Run multiple PHP versions simultaneously (5.6 through 8.4) with per-user configuration and custom limits.
Built-In Security Suite: Includes Coraza WAF for OWASP protection, mandatory 2FA, ImunifyAV malware scanning, domain-specific IP blocking, and firewall management, all included in the free tier.
OpenCLI with 100+ Commands: A full command-line interface lets admins handle user creation, domain management, PHP switching, WAF configuration, and more directly from the terminal.
Two-Panel Architecture: OpenAdmin handles server-level tasks like plan creation and user management, while OpenPanel gives end users control over their own websites, databases, and settings.
One-Click App Installers: Deploy WordPress, Node.js apps, and Python applications with built-in auto-installers and a dedicated WordPress Manager.
DNS and Email Management: Full DNS record support (A, AAAA, CNAME, MX, TXT, SRV, NS, wildcard) plus email with SPF, DKIM, and DMARC configuration.

Pros

Free Community Edition: Core features including resource limiting, multiple web servers, backups, and security tools are free forever for up to 3 users and 50 websites.
Strong Isolation and Security: Docker-based containerization provides user isolation out of the box, something that requires extra licensing (CloudLinux CageFS) with cPanel.
Lightweight Performance: OpenPanel is designed to run smoothly on low-end VPS servers and lightweight hosting environments while maintaining fast performance and responsive management tools.
Lower Licensing Costs: Enterprise pricing starts at €14.95 per month, making it a more affordable option than many traditional hosting panels with account-based licensing models.
Modern, Clean Interface: Dark-mode-friendly UI with real-time charts, a built-in web terminal, and mobile-responsive design that users describe as clean and fast.
Quick Setup: Install on a clean Debian or Ubuntu server with a single bash command in about 5 to 10 minutes.

Cons

Steeper Learning Curve For Beginners: OpenPanel includes advanced server management tools and Docker-based infrastructure that may feel complex for users who prefer a simple point-and-click hosting experience. Many advanced tasks still involve command-line usage.
Community-Based Support for Free Tier: Community Edition users mainly rely on Discord, GitHub, forums, and documentation for troubleshooting, while priority support and consulting are tied to paid plans.

Use Cases

Small Hosting Providers: Launch a web hosting business without expensive licensing fees. OpenPanel's free Community Edition supports multiple users with isolated environments, and the Enterprise Edition scales with white-labeling and billing integration.
Developers Managing Multiple Projects: Run different PHP versions, web servers, and databases per project on a single server. The OpenCLI and Docker isolation make it easy to keep environments clean and separate.
Budget-Conscious Website Owners: Host personal or small business websites without paying monthly panel licensing fees. The free tier covers up to 50 websites with full security features included.
Agencies Migrating from cPanel: Cut hosting costs by switching from cPanel to OpenPanel. The Enterprise Edition includes migration tools and supports cPanel backup imports for smooth transitions.
Security-Focused Deployments: Host client sites where isolation matters. Each user's containerized environment prevents cross-account vulnerabilities, with WAF protection, 2FA, and malware scanning built in.

Frequently Asked Questions

Is OpenPanel free to use?

Yes. OpenPanel offers a free Community Edition for self-hosting that supports up to 3 user accounts and 50 websites. It includes core features like resource limits, multiple web server support, backups, security tools, and application installers. The Enterprise Edition starts at €14.95 per month per server and adds features like email hosting, FTP management, white-labeling, Docker controls, and priority support.

How does OpenPanel compare to cPanel?

OpenPanel is a modern, Docker-based alternative that provides built-in user isolation, a lighter resource footprint, and significantly lower costs. cPanel offers a more mature ecosystem with broader third-party integrations and deeper enterprise tooling. OpenPanel is better suited for developers and cost-conscious providers, while cPanel remains stronger for non-technical users and large agencies.

What operating systems does OpenPanel support?

OpenPanel runs on Linux, specifically Debian and Ubuntu. Installation is done via a single bash command on a clean server, and the setup wizard handles Docker, database configuration, and SSL automatically.

What web servers and databases does OpenPanel support?

OpenPanel supports Nginx, Apache, OpenLiteSpeed, OpenResty, and Varnish as web servers. For databases, it supports MySQL, MariaDB (Enterprise), and Percona. Additional services like Redis, Elasticsearch, and Memcached are also available.

Can I migrate from cPanel to OpenPanel?

Yes. The Enterprise Edition includes migration tools and supports cPanel backup imports. You can transfer existing sites, databases, and configurations to OpenPanel without starting from scratch.

How does user isolation work in OpenPanel?

Each user account runs inside its own Docker container with dedicated instances of MySQL, PHP, and caching services. This means one user's misconfiguration or security issue cannot affect other accounts on the same server.
