  Cockpit is a free, open-source web-based admin GUI. It’s modular and extensible to meet your specific needs, with a lot of customization options across the board.

  Cockpit is released under the MIT license and is completely free to use on any project. There are no limitations to how many projects you can host, but note that your ISP may limit the number of open ports you can run in order to handle high volumes of traffic, which could cause performance issues. If you’re unsure about hosting Cockpit on your website, chat with your host provider or support for more information about this.
