VestaCP's successor
What Hestia Control Panel gives you on a small server
Hestia Control Panel is a free GPLv3 hosting panel built on the VestaCP codebase and carried forward where VestaCP stopped. Nginx and Apache with PHP-FPM serve the sites while Bind handles DNS with clustering. The mail side arrives complete with Roundcube, SpamAssassin and ClamAV. Databases run on MariaDB, MySQL or PostgreSQL, with Let's Encrypt issuing wildcard certificates from inside the panel.
What separates it from the other free panels is how little it needs. One core and a gigabyte is a real minimum rather than an optimistic one, which matters a great deal when the panel is competing with the sites for the same memory. The project also asks for KVM or LXC virtualisation and warns against OpenVZ, so a cheap container VPS is the wrong home for it. Every plan here runs on KVM.
