What is OpenPanel?

What it is

OpenPanel is an open-source web hosting control panel built around containers, and it lives in the self-hosted infrastructure operations ecosystem for Docker and Podman hosting panels. It is offered as a free community edition and as a fully supported commercial version.

The concrete problem it solves is weak isolation in traditional shared hosting control panels, where many users often share a single Apache, MySQL, or PHP runtime. OpenPanel provisions a dedicated Podman context for each user, with a separate web server container, database container, PHP-FPM containers, private network, and scoped storage volume. This design aims to provide VPS-level isolation on shared hosting infrastructure without requiring each customer to operate a full VPS.

Key capabilities

  • OpenPanel gives each hosting user an isolated Podman environment with a private network and scoped file storage.
  • It supports dedicated web server containers per user, including Nginx with Varnish, Apache with Varnish, OpenLiteSpeed, and OpenResty.
  • It can run separate database containers per user for MySQL, MariaDB, Percona MySQL, or PostgreSQL, while using MySQL for panel metadata.
  • It allows multiple PHP-FPM versions, and the documentation diagram shows Node.js and Python applications.
  • The server stack includes OpenAdmin for administration, Caddy for reverse proxy and SSL, BIND9, and phpMyAdmin for database access.
  • Users can set CPU, RAM, and storage limits, view domain logs, restart services, modify server configurations, and configure backups.
  • It provides billing integrations for FOSSBilling, WHMCS, Blesta, and paymenter.org.

Who uses it and how

  • Hosting providers use OpenPanel to run shared hosting on containerized infrastructure while giving each customer an isolated environment.
  • Server administrators use OpenAdmin to manage users, DNS, SSL, reverse proxy behavior, database access, and activity logs.
  • Site owners and developers use the user panel to change web server settings, select PHP versions, manage databases, restart services, inspect logs, and configure backups.
  • Billing teams integrate OpenPanel with FOSSBilling, WHMCS, Blesta, or paymenter.org to connect hosting provisioning with billing systems.

Getting started

The README excerpt does not list a package manager, Docker image name, or hosted deployment command. It points to openpanel.com and documentation for community and commercial editions, security, extensions, billing integrations, and per-user Docker configuration.

When to use it — and when not to

OpenPanel is suitable when operators need container-based per-user isolation for web hosting and can operate Podman, Caddy, BIND9, MySQL, phpMyAdmin, storage volumes, resource limits, and backups. It is less suitable if a team needs a mature, clearly licensed project or a simple installation path, because the repository is new, lists zero contributors, has four open issues, and uses a NOASSERTION license. Teams wanting commercial support can consider the fully supported version, while teams needing clear licensing or established community signals should evaluate that risk.

OpenPanel - Web Hosting Control Panel

OpenPanel is a web hosting control panel built around containers. Every user gets a fully isolated environment: dedicated web server, dedicated database, private network, and scoped file storage - delivering VPS-grade security on shared hardware.

What is OpenPanel?

OpenPanel is a web hosting control panel that uses containers to give every hosting user a completely isolated environment. Unlike traditional control panels that share a single Apache, MySQL, or PHP runtime across all users, OpenPanel provisions a dedicated Podman context per user: each with their own web server container, database container, PHP-FPM containers, private network, and storage volume. The result: VPS-level isolation on shared hosting infrastructure, without the VPS price tag.

OpenPanel vs OpenAdmin

  • The OpenAdmin offers an administrator-level interface where you can efficiently handle tasks such as creating and managing users, setting up hosting plans, and editing OpenPanel settings.
  • The OpenPanel interface is the client-level panel where end-users can manage their containers: edit settings, configure limits, manage backups, create websites and more.
