With the high cost and lock-ins of popular web hosting control panels such as cPanel  and Plesk , many people seek open-source alternatives. Being open-source, these control panels can be modified and tailored to your specific needs. Many of them also have comparable features to their proprietary counterparts. Below is a feature comparison chart for the 10 best open-source web hosting control panels of my choosing. My rankings are based on personal experience, usability, and features. There is also a brief description, screenshots, and link to a demo (if available) below. While there are many different types of open-source control panels, this article focuses primarily on control panels designed for web hosting. I hope this helps some of you with your decision of which control panel to use. If there are any other open-source or free web hosting control panels that you think are worth mentioning, leave a comment, and I will make sure to give it an honorable mention:
