What Are Codex Pets?

Codex pets are virtual companions that live in your OpenAI Codex CLI terminal. Use /pet hatch to hatch a new pet, or install a custom pet package to personalize your coding companion. Custom Codex pets are defined by a pet.json file and a spritesheet.webp image — anyone can create and share one. Browse the gallery above to find community-made pets, copy the install command, and run it inside Codex to get your new companion.

Frequently Asked Questions

How do I install a custom Codex pet?
Copy the install command from any pet listing on this page, then run it inside your OpenAI Codex CLI session. The pet will replace your current companion.
How do I hatch a Codex pet?
Inside the Codex CLI, type /pet hatch to hatch a new pet from your available packages.
How do I create a custom Codex pet?
A Codex pet requires two files: pet.json (metadata and animation config) and spritesheet.webp (sprite frames). Host both in a public GitHub repo and submit it here for review.
What do Codex pets do?
Codex pets are animated companions visible in the Codex CLI sidebar. They grow, animate, and react as you code.
