# Plans and compatibility

Heard supports macOS 14 or later. Claude Code, Codex CLI, and the Codex app have first class support. Other compatible terminal agents can use the open source universal wrapper.

| Cursor command line workflow | Universal wrapper      | Support depends on terminal output             |
| OpenClaw and Hermes Agent    | Universal wrapper      | No dedicated adapter today                     |
| Other command line agents    | Universal wrapper      | Test compatibility with `heard run`            |

## Platform compatibility

* **macOS:** supported on macOS 14 or later
* **iPhone:** browser pairing is available through Heard Power while the Mac remains the host
* **Windows and Linux:** the supported managed product is not available today
* **Android:** not supported today

Use the most specific integration available. Native adapters provide richer event context than the universal wrapper.
