Developer Island

Developer Island
The developer status bar Windows never had.

Developer Island is a native, floating capsule at the top of your Windows screen. It shows your Claude Code and Codex usage, what's playing, your focus timer, your next meeting and your machine's health at a glance, and opens into a full view when you click it.

Demo mode with invented data, rendered by the app itself (--snapshot). In the live app, the states morph with springs.

Why Developer Island?

AI coding tools spend tokens and plan limits where you can't see them, and the rest of a developer's day is scattered across a terminal, a media app, a calendar and Task Manager. macOS has the notch and the Dynamic Island idea; Windows has nothing in that spot. Developer Island puts the few things you glance at all day into one small capsule that stays out of your way: native, local-first and cheap enough to run all day.

AI usage

- Claude Code and Codex usage from their local logs: today's fresh and processed tokens with a full breakdown (input, cache write, output, cache read), sessions and model.
- A token metric of your choice in Settings: fresh tokens (input, cache writes and output, the default) or all processed tokens including cache reads, for the capsule, peek, tooltips and graph. Every figure says which one it is.
- Plan usage where the tool reports it: Claude's 5-hour and weekly windows with reset times, and Codex's windows from its own logs. Never computed from token counts.
- A 26-week usage graph with a tooltip per day, and an estimated API equivalent at public list prices (in the expanded view only).
- The compact capsule reads like Claude 1.12M · 72%, or 2.68M incl. cache reads · 72% with all processed tokens.
- Claude Code alerts: a live activity when Claude Code needs your…
