Radar

Radar is a menubar application that runs on macOS, Windows and Linux, allowing users to view selected data without leaving the current workspace. It presents a collection of metrics—such as balances, analytics, or custom API results—in a single, always‑accessible pane. Users can add data sources with a single click from an expanding list of built‑in collections or by connecting their own APIs, and the app refreshes the information in the background to keep it current.

The tool emphasizes privacy by performing all API communication locally on the user’s device, requiring no account creation. It offers simple analytics like line charts, threshold‑based alerts, and keyboard shortcuts for quick access, and it adapts to light or dark system themes. A free trial period is available, after which a free tier with limits or a one‑time purchase can be used. The design targets developers, analysts, and anyone who needs frequent, glanceable updates on key metrics while staying focused on other applications.
