FAQ

Common questions

Which terminals are supported?

iTerm2, Ghostty, Warp, Terminal.app, Alacritty, Kitty, WezTerm, Hyper, and more. Coding Island also supports tmux sessions and split panes with precise window matching.

Which AI agents does it support?

Claude Code, Coco / Trae, and Codex out of the box through a shared provider architecture. The hook system is extensible for future agents.

How does permission approval work?

When an agent requests to run a tool (file edit, bash command, etc.), the notch shows the tool name and what it wants to do. You can Allow or Deny right from the session row — no need to switch to the terminal.

Is my data sent anywhere?

No. Coding Island runs fully locally. Session data, chat history, and token statistics never leave your machine. The only optional analytics are anonymous app-launch and session-start events.

Does it work on external monitors?

Yes. You can select which screen to display on, including external monitors without a notch. The app adapts the overlay position accordingly.

What are the system requirements?

macOS 15.6 or later. The app is a lightweight native macOS binary — no runtime dependencies, no Docker, no Node.js.

How does remote session monitoring work?

Coding Island sets up an SSH reverse tunnel from the remote machine. Agent events are forwarded over the tunnel to your local Unix socket, letting you monitor and approve remote sessions the same way as local ones.
