A crisp red and white science-fiction theme for Codex Desktop.

Eight moods. One real workspace.

These repository-provided composites show how Dream Skin can reshape the home and task views while the native interface stays interactive.

A theme layer, not a fake interface

Dream Skin changes the atmosphere around the official app while preserving the controls you already use.

01

Real Interactive Interface

The sidebar, suggestion cards, project picker, task content, menus, and composer remain native Codex controls.

02

Use Your Own Image on macOS

The macOS studio can prepare a supported local image and turn it into a home banner and task background.

03

Windows & macOS Support

The repository includes separate, platform-aware install, start, verify, and restore workflows.

04

No Official App Modification

Dream Skin does not patch .app, app.asar, WindowsApps, or the official code signature.

05

One-click Restore

Platform launchers and scripts stop the themed session and reopen the official appearance.

06

Local CDP Injection

The theme is applied to expected Codex renderer targets through a loopback-only debugging endpoint.

From repository to a new look

  1. 1. Install Dream Skin

    Follow the platform guide and use the real installer entry included in the repository.

  2. 2. Apply the available theme

    Use the platform launcher. On macOS, you can also prepare your own supported image.

  3. 3. Launch Codex

    Dream Skin starts the official app with a local themed session; your normal controls remain usable.

Designed around the Codex you already use

The visual treatment sits behind native navigation, suggestion cards, project controls, tasks, and the composer instead of replacing them with a screenshot.

A bright, low-noise workspace with cool glass-like surfaces.

Clear safety boundaries

CDP is powerful. Dream Skin narrows its use to local Codex targets, but a themed session should still be treated as a sensitive local debugging session.

  • The CDP listener binds only to the local loopback address.
  • The official .app, app.asar, WindowsApps package, and code signature are not modified.
  • API keys, Base URLs, and model-provider settings are not automatically rewritten.
  • Do not run untrusted local software while a themed CDP session is active.
  • A Codex update can require Dream Skin to be reapplied or adapted.
  • This is an independent project, not an official OpenAI product.

Frequently asked questions

What is Codex Dream Skin?

It is an open-source theme layer that launches the official Codex Desktop app with CSS and decorative interface elements injected through local CDP.

Is Codex Dream Skin an official OpenAI product?

No. It is an independent open-source project and is not affiliated with or endorsed by OpenAI.

Does it modify the Codex installation?

No. The project does not patch the official .app, app.asar, WindowsApps package, or code signature.

Does it support Windows?

Yes. The repository includes Windows install, start, verify, and restore scripts for the official Store-installed Codex app.

Does it support Apple Silicon and Intel Mac?

Yes. The macOS workflow validates the installed official Codex app and supports both Apple Silicon and Intel Macs.

Can I use my own background image?

The documented macOS studio supports local PNG, JPEG, HEIC, TIFF, and WebP images. The current Windows workflow does not document the same image picker.

How do I restore the default Codex appearance?

Use the platform Restore launcher or restore script. It stops the recorded themed session and reopens the official app.

Will it continue working after Codex updates?

Not always without action. App updates can change renderer details, so you may need to reinstall, reapply, or wait for a compatibility update.

Does it change my API configuration?

It does not automatically change API keys, Base URLs, or model providers. Theme configuration and API provider configuration are separate.

Where can I report a problem?

Use the issue templates in the swg209/Codex-Dream-Skin GitHub repository and include your platform and verification results.
