At a Glance:
OpenPanel is a Docker-based web hosting control panel that provisions dedicated web servers, databases, and private networks for each user, delivering VPS-grade isolation on shared hardware and supporting multiple Linux distributions.
Overview:
OpenPanel is a web hosting control panel designed for hosting providers. It replaces the traditional shared-service model—where all users rely on the same web server or database instance—with a fully isolated Docker context for every account. Each user receives dedicated containers for their web server, database, and PHP processes, along with a private network and scoped file storage. The platform separates administrative control, provided through OpenAdmin, from client-level management in the OpenPanel interface. This allows end users to manage services, view logs, configure backups, and run multiple PHP versions independently, while administrators handle user provisioning and plan management.
Key Decision Points:
Docker-backed user isolation: The panel uses Docker containers to provide each user with a private web server, database, and network environment, which fundamentally separates it from panels that share system-level services.
Split interfaces: Administration is performed through OpenAdmin, while end users manage their containers, websites, and settings through the OpenPanel client interface.
Billing integrations: The panel integrates with FOSSBilling, WHMCS, and Blesta, allowing hosting businesses to connect account provisioning with their existing billing stack.
Migration paths: Administrators can import accounts directly from cPanel and CyberPanel backups, which is relevant for providers considering a platform switch.
OS-agnostic deployment: OpenPanel supports Ubuntu, Debian, AlmaLinux, RockyLinux, and CentOS, with explicit version recommendations for AMD and ARM CPU architectures.
Core Features:
Dedicated per-user services: Each account runs its own MySQL, Percona, or MariaDB container and can choose from Apache, Nginx, OpenLitespeed, or Openresty with Varnish as the web server.
Client-level container management: End users can edit container settings, configure resource limits, manage backups, create websites, run multiple PHP versions, and restart their services.
Activity logging: A detailed log records all user actions, providing visibility over client-side operations.
White-label presentation: The panel can be rebranded, letting hosting providers present the control panel under their own identity.
Plan-based provisioning: Administrators can create hosting plans and assign users through the OpenAdmin interface.
Use Cases:
Hosting providers seeking a control panel that isolates users at the container level instead of sharing system-wide services across accounts.
Server administrators who need to import existing accounts from cPanel or CyberPanel backups and manage them through a Docker-based platform.
Managed hosting services that want to give clients the ability to restart services, view domain logs, switch PHP versions, and configure their own backups without granting access to the underlying host system.
Open-Source Alternative Value:
OpenPanel is available under a free community edition, making its Docker-based user isolation model accessible without mandatory commercial licensing. Hosting providers can deploy the panel on multiple Linux distributions and evaluate its dedicated-service architecture—where each user gets a private web server, database, and network—without immediate vendor commitment. The project supports data import from cPanel and CyberPanel backups, which reduces migration friction for users moving away from proprietary or traditional shared-service control panels. A commercial version exists alongside the free edition for those who need additional support.
