Definition
cPanel is a web-based hosting control panel that runs on a Linux server and lets a non-technical user manage email accounts, databases, files, DNS zones, SSL certificates, backups and one-click installs of WordPress and other software through a browser, without touching the command line. It is the most widely deployed panel on shared and reseller hosting, so familiarity with one cPanel host largely transfers to any other. Administrators use the companion tool WHM to set server-wide policies, define hosting packages and create reseller accounts; both are licensed per account or per server rather than bundled free. Since 2019, cPanel has billed hosts on a per-account tier rather than a flat server fee, which pushed many hosts and resellers toward alternatives such as Plesk, CyberPanel, CloudPanel, HestiaCP and aaPanel. Despite that cost pressure, cPanel remains the de-facto standard for Linux shared hosting in 2026, mainly because of its installed base and the AutoSSL, cron, and backup tooling built into the interface.
How it works
cPanel itself is the customer-facing dashboard; WHM (WebHost Manager) is the administrator-facing companion that handles server-wide settings, package definitions and reseller account creation. Both run together on the host's server and are licensed per account or per server.
Why it matters
For shared and reseller hosting, cPanel familiarity is a real value: anyone who has used one cPanel host can use any other. For hosts and resellers, the per-account pricing has become the main reason to look at alternatives. For end users on a managed plan, the control panel may be hidden entirely.
