10 Best DeepSeek Harness Themes and Skins (2026)
Every DeepSeek Harness theme and skin plugin in FindHarness's curated index, ranked by stars — whale skins, Claude-style themes, a Windows XP desktop, and more.
DeepSeek Harness (dsh) ships one default look for its Web UI. Everything else — whale-girl skins, Claude-style palettes, a full Windows XP Luna desktop, custom fonts — comes from the themes-appearance plugin category. Here are all ten theme plugins in FindHarness's curated (awesome-list) index, ranked by GitHub stars as of August 2026.

All ten are pulled from the themes-appearance category in FindHarness's source: awesome index — the community-curated awesome-dsh-plugin list, not the broader, unreviewed discovery set. None have been security-reviewed by FindHarness; read the plugin security checklist before installing from GitHub, especially for appearance plugins that touch the client bundle.
Why themes exist as a plugin category at all
Because dsh has no separate "theme file" format — a skin, a wallpaper layer, or a font switcher is implemented the same way any other capability is: a plugin that registers into the Cordis tree and, in this case, ships CSS/assets and hooks into the Web client's rendering. That's why the category spans wildly different scopes, from a single-purpose wallpaper plugin to a full desktop-metaphor theme like the Windows XP one below.
The ten theme plugins
1. dsh-deep-whale — the whale-girl skin series
github.com/small-tailqwq/dsh-deep-whale · 605 stars
By far the most-starred theme in the curated index. A "maid-atelier" whale-girl skin series for the Web UI — the character-driven aesthetic is a recurring pattern in the dsh theme ecosystem, and this is the one that took off.
dsh plugin --profile web add github:small-tailqwq/dsh-deep-whale
2. dsh-skin — Codex-style switcher plus wallpaper
github.com/kingao294/dsh-skin · 10 stars · MIT
A Codex-style skin switcher combined with a custom wallpaper layer that has opacity and blur controls. Good starting point if you want a skin picker rather than a single fixed look.
dsh plugin --profile web add github:kingao294/dsh-skin
3. dsh-client-ui-skin-claude — a Claude-style theme
github.com/pakiknowledge/dsh-client-ui-skin-claude · 3 stars
A warm-black canvas with a clay accent color and serif typography, following the native light and dark theme toggle rather than replacing it outright. If you've come from Claude Code and want something visually closer to what you're used to, this is the direct match in the curated index.
dsh plugin --profile web add github:pakiknowledge/dsh-client-ui-skin-claude
4. dsh-blue-whale — DeepSeek-Chat brand colors
github.com/starslittle/dsh-blue-whale · 3 stars · MIT
A blue-whale skin using DeepSeek-Chat's brand color (#4D6BFE) across light and dark, following the built-in appearance mode. This is the pick if you want dsh to visually match DeepSeek's own consumer chat product rather than diverge from it.
dsh plugin --profile web add github:starslittle/dsh-blue-whale
5. dsh-any-background — full custom color and wallpaper
github.com/tkingxiao/dsh-any-background · 3 stars · MIT
Lets you fully customize the Web UI with a custom theme color, a background wallpaper, and fine-grained opacity controls. Less about a specific pre-built look and more about a toolkit for building your own — the plugin to reach for if none of the fixed skins above match what you want.
dsh plugin --profile web add github:tkingxiao/dsh-any-background
6. dsh-font — 130 font options
github.com/tianyhjg-lab/dsh-font · 2 stars
A font switcher offering 99 UI fonts and 31 code fonts, with CJK-Latin pairing stacks (relevant if you read/write both Chinese and English in the same session), instant apply, and localStorage persistence. Unlike the others on this list, this one changes typography rather than color or layout — worth combining with a color-focused skin.
dsh plugin --profile web add github:tianyhjg-lab/dsh-font
7. dsh-client-ui-theme-xp — a Windows XP Luna desktop
github.com/samizuhm/dsh-client-ui-theme-xp · 2 stars · MIT
The most ambitious entry here: a floating window manager with taskbar and desktop icons, wrapped in an era-accurate Windows XP Luna skin. This isn't a color palette swap — it restructures the client into a desktop-metaphor interface, which is a genuinely different interaction model from the default single-pane Web UI.
dsh plugin --profile web add github:samizuhm/dsh-client-ui-theme-xp
8. dsh-plugins (theme-gallery) — fifteen theme families
github.com/wsxwj123/dsh-plugins (packages/theme-gallery) · 1 star · MIT
Fifteen curated theme families with complete light and dark palettes that follow the native Light, Dark, and Follow-system modes. If you want variety without committing to one specific look, this bundles the most options in a single install. Note this plugin lives inside a monorepo at packages/theme-gallery — check the repository's own README for the exact install path.
dsh plugin --profile web add github:wsxwj123/dsh-plugins
9. dsh-wallpaper — a focused wallpaper skin
github.com/chinarxq/dsh-wallpaper · 1 star
A wallpaper skin for the Web UI: an image background with opacity, mask, and blur controls. Narrower in scope than dsh-any-background above, and a reasonable choice if all you want is a background image without touching accent colors or typography.
dsh plugin --profile web add github:chinarxq/dsh-wallpaper
10. dsh-theme-cyberpunk2077 — Night City
github.com/tommy00748/dsh-theme-cyberpunk2077 · 0 stars
The most elaborate single-theme package on this list: an NC yellow and neon cyan identity, CRT scanlines, a "Kiroshi hover lock-on" effect, a combat-state HUD, synthesized typewriter and message sound effects, and hidden easter eggs referencing the source material. Zero stars as of this writing doesn't mean low quality — it's simply new and hasn't circulated widely yet.
dsh plugin --profile web add github:tommy00748/dsh-theme-cyberpunk2077
How to install a theme plugin
None of the ten plugins above have a published npm package in FindHarness's index, so every install is a GitHub source install:
dsh plugin --profile web add github:<owner>/<repo>
Because appearance plugins tend to ship a prepare/build step for their CSS or client assets, you're likely to hit the allowBuilds prompt on first install — see How to Install DeepSeek Harness Plugins for what that means and how to pin a commit with #<sha> before granting it.
FAQ
Can I install more than one theme at once?
Technically yes, but two theme plugins that both restyle the same UI surfaces will likely conflict — later-loaded CSS tends to win, unpredictably. Pick one primary skin; pair it with a narrowly-scoped plugin like dsh-font if you want to layer typography on top.
Do these themes work with dark mode?
Several explicitly say they follow the native light/dark toggle (dsh-client-ui-skin-claude, dsh-blue-whale, dsh-plugins theme-gallery) rather than forcing one mode. Others, like the Windows XP or Cyberpunk themes, are built around a specific aesthetic and may not have a dark/light variant — check each plugin's README before installing if that matters to you.
Is a theme plugin safer than a functional plugin, since it "just" changes colors?
Not necessarily. A theme plugin still runs as ordinary code inside your dsh installation and, like any plugin, can ship a prepare script that executes at install time. "It's just CSS" is not a security guarantee — treat theme plugins with the same scrutiny as any other GitHub install.
Why does dsh-deep-whale have so many more stars than everything else?
FindHarness only reports GitHub stars, not usage or quality signals beyond that. A large star gap usually reflects how early and how widely a repository was shared in the community rather than a measured quality difference — several lower-starred entries here (like the Windows XP theme) are more technically elaborate.
Where do I find themes not in this curated list?
FindHarness's full catalog at /plugins includes plugins beyond the awesome-list curated set. Filter by the themes-appearance category to see everything discovered so far, curated or not.
