Show HN: Whiplash – macOS menu bar app to track concurrent CLI agent sessions (arv.in)

A new macOS menu bar app, Whiplash, has been introduced to streamline the management of concurrent CLI agent sessions, including those from Claude Code, Gemini CLI, and Codex. This utility allows developers to see what's running, idle, or completed without the hassle of switching between different windows. With a simple keyboard shortcut, users can easily open Whiplash to add tasks directly from their editor or terminal, significantly enhancing productivity in multi-tasking environments. Whiplash automatically detects running sessions, linking tasks to their contexts without the need for manual tagging. It is designed as a lightweight popover in the menu bar, avoiding distractions from dock icons or window management. Built entirely with Swift and SwiftUI, it requires no external dependencies, ensuring a fast and native experience. Users can store task data locally with no accounts or cloud sync needed, preserving privacy. The open-source app is compatible with macOS 14 Sonoma or later and can be easily downloaded or built from source, making it an appealing tool for developers who often juggle multiple coding tasks simultaneously.
