Muster is a native macOS menu bar app that monitors and manages multiple AI coding agents (Claude Code, Codex, Cursor), alerting you when one needs input and letting you approve or answer prompts without switching apps. It cleverly aggregates session files and optional hooks to unify agent oversight, with remote SSH support for distributed sessions.

Target audience: developers using multiple AI coding assistants
