Create your own Codex skin
Your Codex workspace does not have to stay generic. Start with a preset, your image, or your colors, then preview a readable skin before you download it.
Choose a Native Theme for colors and fonts, or a Dream Skin for an image-led workspace. You see what is in the export, what to review before applying it, and how to restore your appearance if you change your mind.

Your image stays in this browser.
The .dreamskin archive is an unsigned review artifact.
Designed for a reviewable workflow
Start your way
Begin with a preset, your own image, or a blank color system.
Preview the work
Review Home, Task, and Diff before you export.
Keep the next step visible
See the export mode, application guidance, and restore path before you apply anything.
A good-looking theme still has to work
A background that hides code, an accent that disappears in a diff, or an export you cannot explain is not a finished skin. You need to see the work surfaces, catch problems before export, and know what happens after download.
Your image can fight your interface.
Bright or detailed areas can make text, controls, and diff states harder to read.
A color palette is not a workspace preview.
You need to inspect the states you use, not just a set of swatches.
Download is not the last step.
A useful skin includes an application path, a verification step, and a way back to the default appearance.
From an idea to a Codex skin in three steps
Choose your starting point
You remix a preset, add an image, or begin with colors.
Tune the work surfaces
You adjust the skin and review Home, Task, and Diff.
Export and apply carefully
You choose an output, review the guidance, then verify or restore.
Make a skin for the way you work
Personal workspace
You like the image on your desktop, but using it behind your editor turns the interface into visual noise.
Your workspace carries your style while text, controls, and diff states remain deliberate and readable.
Position the image, tune the surface, then inspect each work view.
Fast preset remix
You want a better-looking Codex theme, but starting from a blank palette feels like work.
You begin from a licensed starter preset and make a version that feels like yours.
Pick a preset, change the few controls that matter, and export.
Native-first setup
You want a cleaner theme without adding a background image or using a local Skin workflow.
You leave with a focused colors-and-fonts theme and a clear import path.
Create a Native Theme, validate it, then import it in Codex settings.
Build with context, not guesswork
Real work-surface preview
Preview Home, Task, and Diff states instead of judging a skin from a color picker alone.
You can spot whether the theme still makes sense where you actually work.
Image controls that stay readable
Adjust image position, zoom, dim, blur, and panel opacity beside your theme colors.
You can keep the image you chose without asking it to compete with the interface.
Checks before export
The Studio checks theme fields, contrast, diff colors, image readability, font fallbacks, and mode-specific compatibility.
You get clear errors and warnings before a bad setting becomes a downloaded file.
Two outputs, clearly separated
Export a Native Theme for colors and fonts, or a Dream Skin package for an image-led setup.
You choose the setup that fits your comfort level instead of treating every theme as the same kind of install.
Reviewable download package
Dream Skin exports are designed as a fixed data package with a manifest, theme data, background, preview, rights declaration, integrity summary, and README.
You can inspect what you downloaded before you decide to apply it.
Verify and restore
Application guidance includes a way to check the result and return to the default appearance if needed.
You are not left at a download button when the next step needs care.

Questions before you change your workspace
Is CodexSkin.download an official OpenAI or Codex product?
No. CodexSkin.download is an independent tool and is not affiliated with, endorsed by, or approved by OpenAI or CodexSkin.org. "Codex" and related names may be trademarks of their respective owners.
Do I need an account to create a skin?
No. The MVP is designed to let you create, validate, and export a skin without an account. Cloud saving, sharing, and other account-based features are not part of the current MVP.
Is my image uploaded when I use the Studio?
The Studio is designed to process your image in your browser rather than upload it through the core workflow.
What is the difference between a Native Theme and a Dream Skin?
A Native Theme focuses on Codex-supported colors and fonts and is imported through settings. A Dream Skin is an image-led data package that follows a separate, reviewable local application path with its own platform, verification, and restore guidance.
Does downloading a Skin install it for me?
No. Downloading gives you the export package or theme data. You review the package, follow the applicable instructions, verify the result, and can use the restore path if you want to return to the default appearance.
Make Codex feel like your workspace
Start with what you already have: a favorite image, a color idea, or a preset worth remixing. Shape the skin, check the work views, and choose the export path you can review.
You stay in control of the final application step. Compatibility and local-processing details are shown only where they have been tested.
