ISPConfig is itself open source: ispconfig.org describes it as a BSD-licensed, browser-based control panel for Linux servers that manages websites, email, DNS, databases, FTP and shell users on one server or a multiserver setup. People look elsewhere when they want a different interface, a different web stack, or an app-deployment platform.
Every tool below is under an OSI-approved licence, checked against its repository. They range from classic hosting panels to a server-admin tool and a Docker-based deployment platform.
Licences checked against each repository on November 7, 2026.

Open-source ISPConfig alternatives: FAQ
Quick answers to common questions
Is ISPConfig open source?
Yes. ispconfig.org describes it as BSD licensed. The ISPConfig repository page could not be loaded during this check, so confirm the exact licence file before redistributing.
What is the closest alternative to ISPConfig?
Virtualmin and HestiaCP are the closest, both GPL-3.0 hosting panels covering web domains, mail, DNS and databases.
Can these panels run on any Linux server?
Support varies by project and distribution. Check each project's install docs for supported operating systems.
Is Coolify a replacement for a hosting panel?
Not for mail or DNS hosting. It is a self-hostable deployment platform for applications and databases, so it fits app hosting rather than shared hosting.
Are Webmin and Virtualmin related?
Yes. Virtualmin's repository describes it as a virtual-server web hosting control panel module for Webmin.
