OpenPanel

OpenPanel is an open-source web hosting control panel built on Docker. It is designed for server administration on VPS or dedicated hardware, allowing administrators to provision isolated environments for multiple users on shared infrastructure. By utilizing containerization, the software ensures that each hosting user operates within a private context, preventing the shared runtime issues common in traditional hosting panels.

The software is deployed as a server application and consists of two primary interfaces to separate administrative and client duties. OpenAdmin serves as the administrator panel for managing users, defining hosting plans, and configuring global system settings. In contrast, OpenPanel provides the client-level interface where end-users manage their own containers, edit site settings, configure resource limits, and handle their own backups.

Key features

• Docker-based isolation providing dedicated web servers and databases per user
• Support for multiple web servers including Nginx, Apache, and OpenLitespeed
• Ability to run multiple PHP versions simultaneously for different sites
• Dedicated database options including MySQL, MariaDB, and Percona
• Integration with billing platforms such as FOSSBilling, WHMCS, and Blesta
• Account import functionality for backups
• Resource limiting for CPU, RAM, and SSD storage per user
• Detailed activity logs for tracking all user actions

The architecture utilizes Caddy as a reverse proxy and SSL manager, BIND9 for DNS, and the Docker Engine for container orchestration. It is OS-agnostic and supports a wide range of operating systems, including various versions of Ubuntu, Debian, AlmaLinux, and CentOS. This setup allows users to modify server configurations, view domain logs, and restart services independently without affecting other tenants on the same hardware, effectively mimicking a VPS experience on shared infrastructure.

OpenPanel is a solution for hosting businesses that require high levels of security and user isolation without the overhead of managing individual virtual private servers for every client.
