halfmarble

halfmarble is an AI coding assistant menu-bar app showing Claude Code limits and live sessions on a Mac.

devTopBars is a paid Mac menu-bar application built on cpuTopBars that monitors your system and AI coding sessions at a glance. It displays usage-limit and session bars for Claude Code, network address rows for LAN, WAN, and VPN, and a keep-awake function for specific processes. The app requires macOS and works with the open-source usage-feed plugin for Claude Code to track 5-hour and weekly limits. It also features CPU, GPU, Neural Engine, memory, and disk monitoring, while sending no user data or session information externally. Designed for developers using Claude Code on macOS, it frees up menu bar space and provides quick access to process details.
