cPanel

cPanel (developed by cPanel L.L.C., part of WebPros since 2018) is the most widely used hosting panel in North America and often sold bundled with WHM (WebHost Manager) for resellers. Functionally similar to Plesk: domain/subdomain management, FTP, MariaDB/MySQL, PHP versions, Postfix mail, cron jobs, backup wizard, Let's Encrypt integration, Softaculous installer for CMS. After the 2019/2020 price hike (from ~$15 to per-account pricing) many hosts moved to Plesk or open-source alternatives. In the German market it's rare — netcup, IONOS and Hetzner use Plesk or proprietary panels. If you're migrating from the US market, check before switching whether the target panel can import cPanel backups (.tar.gz in cPanel format).
