DeepSeek Harness (DSH) adopts a plugin-based architecture, allowing users to extend functionality and the interface. The default background is relatively plain. If you want the DSH interface to match the visual style of the DeepSeek official website homepage, the dsh-homepage-skin plugin provides a ready-made solution.

Plugin Overview

This plugin is maintained by yushi-xxh and belongs to the “Fun Skins” category. It injects code to map the visual elements from the DeepSeek Harness official homepage into the background of the local web interface, and supports switching between light and dark themes.

Core Features

  • WebGL fluid light background: Provides flowing dark/light fluid light effects.
  • Dot-line grid background: Builds a grid structure with a sense of spatial depth.
  • Digital point-cloud whale: Renders a whale composed of point clouds in the background.
  • Dark/light theme variants: Dark mode preserves the homepage’s deep-sea blue color scheme; light mode uses light fluid effects with dark gray-blue grid/whale elements.
  • Semi-transparent glass sidebar: Changes the sidebar to a frosted-glass appearance.
  • Responsive hide animation: Automatically hides the grid and whale elements on screens narrower than 768px.
  • Accessibility support: Respects the prefers-reduced-motion setting and disables animations when accessibility animation limits are enabled.

Installation and Activation

  1. Install the plugin:
    Run the following command in the terminal:
    dsh plugin --profile web add dsh-homepage-skin

  1. Verify activation:

    • Restart the dsh web process.
    • Perform a hard refresh in the browser (usually Ctrl+Shift+R).
    • Go to Settings -> General -> Homepage Skin and enable the switch. A green dot next to the title indicates it is enabled.

  2. Check the effect:

    • Behind the chat area, you should see fluid light effects, a dot-line grid, and a digital whale.
    • Switch the appearance to light mode; the background should change to light fluid effects with dark gray-blue grid/whale elements.
    • After disabling the switch, the background should disappear immediately.

Typical Usage

  • Daily use: After enabling the skin in settings, switch between dark mode, light mode, or system theme using DSH’s built-in “Appearance” settings. The skin automatically adapts to the selected variant.
  • Mobile adaptation: When viewed on a phone or tablet (width less than 768px), the grid and whale are automatically hidden, leaving only the fluid background to optimize performance and visual clarity.

Notes and Limitations

  • License: The plugin is open-sourced under the MIT License.
  • UI modification scope: The plugin only modifies background visual elements (fluid, grid, whale) and the sidebar glass effect. It does not modify page layout, information density, brand colors, tab icons, or desktop shell icons.
  • Environment requirements: headless or TUI mode has no web interface, so this plugin is not required.
  • Security reminder: Before installing a plugin, it is recommended to review the source code and license.

Summary

dsh-homepage-skin restores the immersive visual experience of the DeepSeek homepage through a lightweight code patch, without breaking the existing layout. For more details and source code, visit GitHub.
