OpenPets is a desktop pet app for AI coding assistants. Codex Pets focuses on a moderated, agent-readable registry of downloadable Codex pet packs with stable package, API, and MCP discovery.
OpenPets documents a local-first desktop app, MCP server, CLI, and assistant integrations for showing agent status on the user's desktop. Codex Pets is not a desktop status app; it is a public registry and package surface for Codex-compatible pet packs that agents can search, cite, install, and share.
When to choose Codex Pets
You need downloadable Codex pet pack assets and stable slugs.
You want OpenAPI, llms.txt, markdown, JSON, TOON, and MCP discovery.
You need README badge, animated card, iframe, or install snippets.
You want a moderated public gallery that agents can cite directly.
When OpenPets may fit better
You want a local desktop companion app reacting to agent status.
You need local IPC, desktop windows, and assistant lifecycle hooks.
You are choosing an app runtime rather than a public Codex pack registry.
