I'm working with
Codex supports native installation. Other agents can use an independent companion window.
Make it yours.
Select your agent on the pet page. Use Install in Codex for native installation, or Open companion window for other agents.
Keep creating.
Use your pet in Codex or keep its browser window beside your agent. Browser companions are independent unless you opt into the local notification bridge.
Your setup
A little company, your way.
The download contains a Codex-format pet. Other agents can use the browser companion without a native plugin.

INDEPENDENT COMPANION WINDOW
No plugin. No credentials. No chat access.
Drag your pet, try every animation, or let it play on its own. Place the window beside your agent. Always-on-top behavior depends on your browser or window manager.
Hermes, natively.
Extract the downloaded pet folder into your active HERMES_HOME/pets/ (usually ~/.hermes/pets/), keeping existing folders intact. Run hermes pets select <folder-name>, then hermes pets doctor. Shift-click the pet in Hermes Desktop to pop out its transparent overlay.
Hermes currently caps playback at six frames per state. For complete longer cycles, use our browser companion. Official Hermes pets guide. Format checked October 5, 2026; native app not tested here.
A little nudge, when it matters
Real signals. Tiny reactions.
Working, waiting for you, finished, or something went wrong. The optional local bridge turns agent notifications into pet reactions and a small unread badge. It never approves a request or reads your conversations.
Download local bridgeConnect notifications
- Unzip the bridge, keep the files somewhere permanent, and review the included guide. Requires Python 3.10 or newer.
- Run
python3 agent-pets-bridge.py serve, then openhttp://127.0.0.1:4174/companion. - Choose your agent. Try
python3 agent-pets-bridge.py notify --agent claude-code --event attention. - Run
python3 agent-pets-bridge.py hooks --agent claude-codefor a snippet to review and merge into existing hooks. Also supportscursorandgemini-cli. No settings are changed automatically.
OpenClaw, OpenCode, and other agents can call the generic notify command from their own trusted hook or plugin. Their adapters are not auto-configured. Templates were tested with synthetic events, not authenticated live agent sessions.
The bridge runs on your computer. Only status types reach the pet. No prompts, transcripts, or notification payloads are sent to our servers. Stop with Ctrl+C. Browser window chrome and always-on-top behavior depend on your browser; this is not a native transparent desktop overlay.
Native support, checked October 5, 2026
Codex keeps its existing native installer. Hermes has native pet support, with the playback limit noted above. No custom-atlas importer was verified for the other listed agents, so we offer the companion and opt-in notification bridge.
Official integration references: Claude Code, Hermes, OpenClaw, Cursor, Gemini CLI, OpenCode.
Made with care
Little details.
A smoother companion.
Every preview keeps the same scale across frames. The animation player follows Codex’s timing, including the return to idle after an action.
Room to move
Transparent padding keeps hair, hands, and props comfortably inside every frame.
Crisp at any moment
Pixel art stays on a consistent grid, with a shared palette and no soft edges.
Every frame, in view
Each companion’s page links to its sprite sheet and quality reports. We inspect the transitions, as well as the individual poses.
