OpenPanel

Key features

• Per-user isolated containers Each hosting user runs in a fully isolated container with a separate MySQL server, PHP version, and Redis instance plus full root access. Note a runtime variance: the homepage names Docker while the official comparison page names Podman, so confirm the runtime for the version you install.[1][2]

• cPanel backup importer A purpose-built cPanel Backup Importer migrates existing cPanel accounts, and the vendor explicitly positions the panel for teams leaving per-account cPanel and WHM pricing.[1]

• OpenAdmin and user panels with live demos Separate OpenAdmin and user panels cover server-wide and per-user work respectively, and the site links public demos for both so operators can click through before installing.[1]

• OpenCLI terminal with 100-plus commands Every panel action also runs from the terminal: OpenCLI ships over 100 commands covering users, domains, backups, WAF rules, resource limits, and API-endpoint management.[1]

• One-command install on major Linux distros plus ARM Installation runs from a single command on Ubuntu, Debian, AlmaLinux, Rocky Linux, and CentOS, and the panel runs natively on ARM as well as x86 hardware.[1][2]

• WordPress and app autoinstall with backups One-click installs cover WordPress, Laravel, NextCloud, Node.js, and Python apps, with S3 backups, hard CPU, memory, disk, and inode limits, and website visitor and resource analytics per user.[1][2]

• Billing and mail integrations on Enterprise Enterprise connects WHMCS, Blesta, FOSSBilling, and Upmind for client billing, and gates mail server, FTP, container manager, OpenLiteSpeed, and Varnish caching among its premium features.[1][2]

• Fixed per-server pricing with a free Community tier Community is free with a 50-website cap while Enterprise costs a flat 14.95 EUR per server per month with unlimited accounts, priority SLA support, and a 30-day trial needing no credit card.[1]

Who will love it

• Flat per-server pricing plus the cPanel importer directly answers per-account bill shock, and per-user isolation contains noisy neighbours on shared machines.[1][2][3]

• OpenCLI parity with the panels means bulk user, domain, and backup work stays scriptable instead of click-heavy.[1]

• Per-user containers with hard resource limits and one-click WordPress installs match the daily work of hosting many small client sites.[1][2]

Who should avoid it

• The UI ships under a custom EULA and the CLI under CC BY-NC 4.0, so teams requiring OSI-approved open source must exclude it; the vendor comparison table itself marks open source as No.[1][2]

• Only Linux distributions are documented, so Windows Server hosts need Plesk or another panel.[1]

• The observed app catalogue and integration list are narrower than 1Panel's 180-plus app store, so verify any must-have integration before committing.[1][2]
