Codex Skin is a theme and skin resource site for the Codex desktop app, with the core purpose of letting users browse, install, apply, and switch Codex desktop themes while retaining the ability to restore the official appearance at any time.
Purpose The website features a gallery of curated themes for Codex Desktop, covering different visual styles such as dark, light, and high contrast, allowing users to change the appearance of their Codex workspace. Each theme has a fixed six-digit public ID, making it easy to reference precisely within Codex via the plugin.
Main capabilities
- Theme gallery: Centrally displays multiple Codex themes, provides detail views, and marks each theme as Free or Pro.
- Theme application: Through the free, open-source Codex Skin Plugin, install and apply themes within Codex using verified marketplace commands. You need to copy the six-digit theme ID, authorize the device when prompted by the plugin, and then return to the same Codex task to continue.
- Safety and rollback: Themes are pure data (signed structured data and images), containing no arbitrary theme code; compatibility is checked before application; if application fails, the previous theme is retained or the official interface is restored.
- Offline restore: An offline Restore path is provided, allowing removal of the current theme and restoration of the Codex official appearance without website login, Pro permission, plugin cache, or network connection.
- Cross-platform: Supports Codex on macOS and Windows (within the ChatGPT desktop app), with platform-specific validation.
How to use Browse themes on the Codex Skin website, open the details to see whether it is Free or Pro; copy the theme's six-digit ID; install and authorize the device via the free plugin in Codex, then apply the theme. Use Restore when you need to revert; it works even offline.
Use cases Suitable for users who want to personalize their Codex desktop workspace, switch between multiple visual styles, and also need a safe fallback to the official appearance.
Pricing and limitations The website offers free themes, and Pro unlocks the full theme library, new releases, compatibility updates, and theme switching during the active period. Pro's regular price is $19.90 per year, with a launch special price of $9 per year (excluding applicable taxes, billed annually until canceled), and supports manual refund requests within 7 days. The plugin does not replace the official app package, nor does it modify signed system files. After Pro expires, new downloads, updates, switching, and reapplication stop, but the current appearance on the computerwill not be removed remotely, and Restore remains available; after restoration, if you need to apply Pro themes again, a valid Pro permission is required. For other specific details, refer to the official page; features not yet provided are not inferred.
