By Bean
A pixel-art beagle Codex companion with caramel-brown long ears, a small white anthropomorphic body, and a tired, wistful expression.


By Schwifty
A relaxed, filthy-mouthed, psychedelic bush sasquatch who is always half-baked, casually philosophical, sarcastic, and impossible to surprise. He has seen every cosmic truth in existence but still cannot be bothered standing up properly.


By ismailozturk
A clean 2D sticker/vector undead ice king pet inspired by the Night King: pale frost-blue skin, glowing blue eyes, crown-like icy head ridges, and ancient frozen armor.


By gunbos
A mature noir pixel rhythm-strategist pet with relaxed focus, headphone-like fins, and freeform musical motion.

By side_inventory
A compact Sanemi-inspired Demon Slayer wind swordsman pet with scarred face, spiky white hair, open haori, sword, and large green wind-breathing skill effects while Codex is loading.

By side_inventory
A single buff demon-slayer-style muscle mouse who flexes proudly and bounces its chest muscles.
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.
