Agent IslandVS
Vibe IslandVerdict
Pick Vibe Island if you want a native Swift macOS notch control surface that can approve permissions, answer questions, and jump to exact terminal or IDE sessions across a very broad agent list. Pick Agent Island if you want a free MIT-licensed companion on macOS and Windows with a narrower five-agent model, explicit local cost estimates, and no account or telemetry.

A status companion versus a notch control surface
Agent Island emphasizes recognizing state and surfacing the moment a human should return. Vibe Island goes further inside the interaction loop: its official documentation claims permission approval, question answering, and precise jump-back to a terminal tab, split, or IDE window. Users who want to act from the notch should value that difference Review the evidence source
The commercial product covers many more agent and terminal combinations
Agent Island supports five named providers with a deliberately shared model. Vibe Island documents 26 agents plus a long list of terminals and IDEs, including split panes and tabs. That breadth is a genuine advantage for Mac users whose workflow spans less common agents or several terminal environments Review the evidence source
Price, source, and operating systems create the clearest boundary
Agent Island is free, MIT-licensed, and ships on macOS and Windows. Vibe Island is a paid, closed-source native Swift macOS 14+ product sold as a one-time purchase with a trial. This is not a claim that one model is universally better; it is the purchase decision users can verify before comparing smaller features Review the evidence source
Moving from Vibe Island to Agent Island
Install Agent Island from GitHub Releases and initially run it beside the paid app. Map working, waiting, and finished habits to Agent Island’s status surface; use its alert to return to the original terminal or IDE rather than approving from the notch. No historical data or settings are imported. Agent Island does not offer in-panel permission approval, one-click question responses, exact tab or split targeting across the same terminal list, or the same 26-agent breadth, so migration trades control depth for free source-visible cross-platform coverage.

FAQ
Is Vibe Island free?
No. The official documentation describes a one-time purchase with a free trial. Check the official pricing page for the current amount.
Can I run both at once?
Yes, during evaluation. Avoid enabling duplicate sound or notification paths for the same event until you know which app should own the alert.
Is Agent Island a free replacement?
It is a free alternative for state, attention, usage, and local estimates, but it is not a feature-for-feature replacement for direct approvals, question responses, exact jump-back, or the broader agent catalog.
Which is better for a Mac notch workflow?
Vibe Island is better when the notch itself should be a control surface. Agent Island is better when you want a simpler status companion that also runs on Windows.
Does either upload my code?
Agent Island processes supported data locally and has no account or telemetry. The reviewed Vibe Island materials describe a native Swift macOS app, but an equally explicit no-telemetry statement was not found, so consult its current privacy terms.
Does Agent Island monitor Cursor sessions live?
Yes. Cursor has live session state and your-turn alarms in Agent Island 2.1.2, alongside plan and billing-cycle usage.
