Codz Simulator
One workspace.
Every mobile device.
Run and inspect iOS and Android apps in a native Mac app. Your coding harness sees the same screen you do.
The public release is coming soon.
Free · Apple Silicon · macOS 14 or later
From your project to its running app.
Open native iOS, Android, React Native, Expo, or Flutter projects, or install an app build. Keep devices running as you move between harnesses.
Devices together
Simulators, emulators, and USB phones. Compare screens side by side or detach a device into its own window.
People and agents
Connect Codex, Claude Code, Cursor, OpenCode, or any local MCP client. Take control when you need it, with screenshots and logs available to the agent.
Local by default
Projects, run history, and screenshots stay on your Mac. No account or subscription is required.
