Free Codex theme downloads
Free Codex themes.
No account required.
Start with a complete theme pack—not a wallpaper-only effect. Every download includes three responsive background ratios, coordinated tokens, local install tools, checksums, and restore instructions.
Local-first
The compatibility runtime stays on loopback and never patches the signed app.
Reversible
Every pack includes install, validate, start, and restore guidance.
16 original packs
Choose dark, light, quiet, or bold.
The artwork is original to this project and published under the per-pack CC BY 4.0 asset license. UI-state images are illustrative previews; runtime compatibility depends on the current Codex Desktop build.
