Herdbell
Herdbell is an independent native macOS menu-bar app for developers who run multiple AI coding agents. It monitors Claude Code, OpenAI Codex, Cursor, and Google Antigravity locally, then lets users see which agent needs attention, approve or deny requests, reply, and hand work off without switching windows.
At a Glance
- Individual software developers and indie developers
- Developers and technical teams using Claude Code, Codex, Cursor, or Antigravity
- Mac users who run several coding-agent sessions in parallel

Products & Services
A native Mac menu-bar app that connects to locally installed coding agents through their hooks, presents all sessions in one list, surfaces working/waiting/finished states, opens an answer bar at the user's cursor, and supports approvals, replies, notifications, quick replies, and agent handoff.
A built-in handoff feature that extracts a session's goal, completed work, decisions, issues, next steps, and relevant project context from local transcripts/files, then formats a continuation prompt for another agent.
Market Position
Herdbell positions itself as an answer-first, cross-agent Mac popup for people running several coding agents. The official comparison identifies built-in agent notifications, terminal bells, DIY hook scripts, and session-manager dashboards as alternatives; Herdbell differentiates with one list, one shortcut, cross-agent permission/reply handling, and local operation, while acknowledging that it is Mac-only, paid, and not a worktree/diff-review dashboard.
Founding Story
The creator describes the impetus as a practical workflow problem: AI agents were getting smarter, but managing several of them was still a mess. Herdbell was built to put agents in one place, show which are working or waiting, notify the developer when attention is needed, and keep the workflow local without cloud access or API keys.
