What is a Codex pet?
A Codex pet is a small animated companion for the Codex app. Each package includes a pet.json file and a spritesheet so Codex can show states like idle, running, waiting, failed, and review.
About
Browse 904+ animated companions, preview how they move, and install a Codex pet with one command.
Codex Pet is a public gallery for animated pet packages that work with the Codex app. It gives users one place to browse pets, preview animation states, copy an install command, and download the original package when they want to inspect it manually.
The site also gives creators a simple way to submit their own Codex pet. A submitted package is checked for required files, duplicate signals, and basic quality before it goes live.
A Codex pet package is usually built from two files. pet.json defines metadata such as the name and animation states. spritesheet.webp or spritesheet.png holds the animation frames that Codex displays.
After installation, open Codex, go to Settings, Appearance, Pets, and select the custom pet. You can wake it from Codex with /pet.

Open any pet detail page, copy the install command, and paste it into your terminal. The command places the pet under ~/.codex/pets/<slug>/ so Codex can find it.
Pets come from community submissions and curated entries. Every submitted package is checked before it appears in the gallery.

No. Codex Pet is an independent gallery for packages that work with the Codex app. OpenAI provides Codex and the pet feature; this site helps users find and share compatible pets.
