An open-source WHM/cPanel alternative built with plain PHP, FrankenPHP & Tailwind.
JinnPanel is a free, MIT-licensed web hosting manager and control panel designed for single-server setups running AlmaLinux 10. The core philosophy is absolute simplicity and transparency—there are no heavy frameworks, no external dependencies, and no Composer. It is written completely in plain PHP and Tailwind CSS, making the entire backend architecture clean, readable, and easy to audit.
The control panel features secure account isolation where every account runs under its own Linux user and dedicated PHP-FPM pool without needing CloudLinux. It includes a built-in cPanel migration tool that moves sites, mailboxes, databases, and cron jobs via a live API or backup files, automatically translating .htaccess rules for the underlying Caddy engine. Security is fully automated, providing out-of-the-box Let's Encrypt certificates alongside automated configurations for email deliverability protocols like SPF, DKIM, DMARC, and MTA-STS.
The stack consists of FrankenPHP, MariaDB, Stalwart Mail, Cypht webmail, Knot DNS, and SFTPGo. It is currently in public beta, optimized strictly for single-server PHP hosting environments.
