The modern web hosting control panel. A fast, clean alternative to cPanel — built for hosting companies who want full control without the legacy price tag.
Opterius Panel is the open-source web interface that manages hosting accounts, domains, email, databases, SSL certificates, and more. It communicates with the Opterius Agent (a separate closed-source binary) that executes privileged server operations.

The panel cannot perform any server operations on its own. All privileged actions are delegated to the agent via authenticated API calls.
SSH into a fresh server (Ubuntu 22.04/24.04, Debian 12, or AlmaLinux 9) as root and run:
curl -sL https://get.opterius.com/install.sh -o /tmp/install.sh
bash /tmp/install.shThe installer sets up everything automatically: Nginx, PHP-FPM, MariaDB, Dovecot, Postfix, PowerDNS, Roundcube, phpMyAdmin, Certbot, Node.js, the panel, and the agent.
