What Web Server Does Proxmox Use?


Scott Campbell

When it comes to virtualization, Proxmox is a popular and powerful choice for many users. Proxmox VE (Virtual Environment) is an open-source platform that combines virtualization, containerization, and software-defined storage in a single solution. It provides a comprehensive web-based interface for managing virtual machines (VMs) and containers.

Web Server Used by Proxmox

One of the key components of Proxmox VE is the web interface that allows users to manage their virtual environment through a browser. To serve this purpose, Proxmox relies on the Apache web server.

Apache is one of the most widely used web servers globally, known for its stability, security, and flexibility. It has been around since 1995 and has established itself as a reliable choice for hosting websites and applications.

Proxmox leverages Apache to provide a user-friendly and intuitive interface for managing virtual machines and containers. The Apache web server handles incoming requests from users’ browsers, processes them, and serves the appropriate web pages with all the necessary information.

  • Performance: Apache is designed to handle high loads efficiently. It can handle concurrent connections without compromising performance.
  • Security: Apache has a robust security framework with features like SSL/TLS encryption, access control mechanisms, and support for various authentication methods.
  • Flexibility: Apache supports multiple operating systems and platforms.

    It offers extensive configuration options to cater to diverse requirements.

  • Module Support: Apache’s modular architecture allows easy integration of additional functionality through modules. This enables developers to extend the core capabilities of the server.

Customizing the Proxmox Web Interface

While Proxmox uses Apache as its underlying web server, it also provides customization options for the web interface itself. Users can modify the appearance and behavior of the interface by modifying its HTML templates and CSS stylesheets.

The HTML templates are responsible for generating the structure and content of the web pages, while CSS stylesheets define their visual appearance. By understanding and modifying these files, users can personalize their Proxmox experience to suit their preferences or branding requirements.

HTML Templates

The HTML templates used by Proxmox are written in a combination of HTML and Template Toolkit (TT) syntax. Template Toolkit is a powerful template processing system that allows for dynamic content generation.

By editing these templates, users can add or remove elements, change their layout or formatting, and even integrate additional functionality into the web interface. However, caution should be exercised when making modifications to ensure compatibility with future updates.

CSS Stylesheets

Proxmox also provides CSS stylesheets that control the visual appearance of the web interface. These stylesheets define colors, fonts, spacing, and other visual aspects of various elements on the page.

Users can customize these stylesheets to create a unique look and feel for their Proxmox environment. Whether it’s aligning with corporate branding or simply making it more visually appealing, modifying the CSS allows users to tailor the interface to their liking.


In conclusion, Proxmox utilizes Apache as its web server to provide a robust and user-friendly interface for managing virtual environments. Apache’s performance, security features, flexibility, and module support make it an ideal choice for hosting Proxmox’s web-based management system.

Furthermore, Proxmox offers customization options through HTML templates and CSS stylesheets. This enables users to personalize the appearance and behavior of the web interface according to their preferences or branding requirements.
