Overview:
OpenPanel is an open-source web hosting control panel that provides each user with an isolated environment and tools to fully manage it. It is designed for hosting providers and server administrators who want to give their end-users a VPS-like experience, including the ability to run multiple PHP versions, modify server configurations, manage backups, and view domain logs. The project is available in both a community-supported version and a more feature-rich version with hands-on support.
Core Features:
Isolated user environments: Each user gets a dedicated container with its own MySQL, Percona, or MariaDB database, and dedicated web server (Apache, Nginx, OpenLiteSpeed, OpenResty + Varnish).
Dual interface architecture: Separates administrative tasks (user management, hosting plans, panel settings) via OpenAdmin from end-user container management (settings, limits, backups, websites) via OpenPanel.
Billing integrations: Supports integration with FOSSBilling, WHMCS, Blesta, and Paymenter.org.
Account import: Can import accounts from cPanel and CyberPanel backups.
Detailed activity logging: Maintains a detailed log of all user actions.
Low-maintenance design: Each user manages their own services and backups, reducing administrative overhead.
Use Cases:
Hosting providers: Offering isolated, self-managed hosting environments to clients without requiring full VPS administration skills.
Server administrators: Managing multiple users on a single server, with granular control over assigned resources and configurations.
Developers testing multi-version PHP setups: Using per-user isolated environments to run and test different PHP versions simultaneously.
Migrating from cPanel or CyberPanel: Importing existing accounts and backups into the OpenPanel system.
Why It Matters:
OpenPanel provides a self-hosted, open-source alternative to commercial hosting panels by emphasizing user isolation and customization. Instead of a single shared environment, it gives each user a dedicated container with their own database and web server, mimicking a VPS experience. The project supports import from cPanel and CyberPanel backups, making it a practical migration target. Its dual-interface architecture (admin vs. user) allows hosting businesses to delegate container management to end-users while retaining control over plans and users.
