What is CodexThemes?
CodexThemes is a community gallery of Codex themes and Codex skins for the Codex desktop app. Each listing comes with a complete workspace preview, so visitors can see how a theme changes backgrounds, colors, panel treatments and visual accents before choosing it. The collection spans many moods, from dark space-inspired looks to light, character-driven designs.
Rather than packaging themes as manual downloads, the site is built around AI agents: users install a Codex theme by handing it to their agent, or bring a reference image or mood and let the agent build a new one. A separate Skins section collects community design references that can be recreated as working themes. Creators can submit their own work, and the project states it is independent and not affiliated with OpenAI.
