A menu bar app that tracks spending on Claude Code. Bundled portable Node.js + pinned ccusage, 7-day summary, 14-day sparkline, 84-day heatmap, and prompt-cache savings.
A menu bar app that tracks spending on Claude Code. All pricing logic lives in a standalone UsageEngine library with no UI dependencies, making the calculations fully testable in isolation while keeping the SwiftUI interface as a thin presentation layer.
The app bundles a portable Node.js runtime and a pinned copy of ccusage, allowing it to work out of the box with a Homebrew installation and no system dependencies or internet connection.
It provides a 7-day spending summary, a 14-day sparkline, an 84-day heatmap, and estimates how much money prompt caching has saved over time.
