Before you download.
What is a Codex skin?
A Codex skin is a visual customization for Codex Desktop. Native appearance settings change supported colors and fonts. An immersive Dream Skin can add background artwork and translucent surfaces through a separate community runtime.
Is Codex Dream Skin an OpenAI product?
No. It is an independent open-source community project and is not affiliated with or endorsed by OpenAI.
Do theme downloads contain executable code?
No. Codex Skin Lab theme ZIPs contain artwork, settings, instructions, a license, and integrity checks. Codex Dream Skin is installed separately from its GitHub project.
Does the builder upload my image?
No. Your selected image is not uploaded to a server.
Can I restore the normal Codex appearance?
Yes. Use the Codex Dream Skin restore option, confirm the themed session closes, then launch Codex normally.
Are Codex App and CLI themes interchangeable?
No. Native App appearance, immersive Dream Skin recipes, and CLI TextMate-style themes are different customization layers and file formats.
What should I do after a Codex update?
Restore the normal Codex appearance first, confirm the official app works, then check the latest Codex Dream Skin instructions before applying a theme again.
May I redistribute Codex Skin Lab backgrounds?
The original ImageGen backgrounds are available under the CSL Original Asset License 1.0. Review the license on each theme detail page.
