What is CodexPet Nest?

CodexPet Nest is an open-source desktop companion app that places a floating nest beside a user's Codex pet and shows local widgets such as usage, time, countdowns, Pomodoro state, and quick actions. macOS is available first, with more platforms planned.

Is CodexPet Nest affiliated with OpenAI?

No. CodexPet Nest is an independent open-source project and does not imply an official relationship with OpenAI or Codex.

Do community packages run code?

No. Nest packages are treated as data: static images, metadata, layout JSON, and built-in widget slots. They do not run scripts, WebViews, or third-party executable code.

Which languages is the website prepared for?

The site is prepared for English, Simplified Chinese, and Japanese with dedicated crawlable routes and hreflang metadata.

Safety Contract

Packages define presentation and widget slots only. They must not provide executable commands, app paths, shortcut names, scripts, URLs, or hidden local quick action targets.
