About Agent Island

Agent Island is a free, open-source status companion for Claude Code and Codex. It lives in the macOS menu bar, shows live agent state and quota/cost countdowns, calls you when a background turn needs attention, and can auto-resume trusted sessions after resets. Native SwiftUI, local-first, no account, no telemetry.

Features

Live Agent State: Instantly see whether Claude Code or Codex is running, waiting, or idle right from your menu bar.
Quota & Cost Countdowns: Track remaining quota and spend in real time so you never get surprised mid-session.
Attention Alerts: Get called when a background turn needs your input, no more babysitting long-running agents.
Auto-Resume Sessions: Trusted sessions pick back up automatically after resets, keeping your workflow uninterrupted.
Native SwiftUI: Built with Apple's modern UI stack for a fast, lightweight, macOS-native experience.
Local-First & Private: No account, no telemetry, no cloud, everything runs on your Mac.
Free & Open Source: Community-driven and available at no cost. Inspect the code, contribute, or self-modify.

Why Agent Island?

Coding agents are powerful, but leaving them unattended means constantly checking terminals, quotas, and status. Agent Island keeps everything visible so you can stay in flow.
