Overview of Heard

Heard is a macOS voice layer designed for agentic workflows, connecting to Claude Code, Codex, and Cursor. It transforms their text output into intelligent audio summaries, allowing users to stay informed without staring at the screen. Key features include full commentary for hands-free monitoring, silence until errors or decisions arise, project-level summarization for parallel agents, and mobile pairing for remote listening. Heard is open source and free for personal use, making it an attractive option for developers who want to multitask while their AI agents work.

Why Look for Alternatives

While Heard offers a unique voice-first experience, it has limitations that may prompt users to seek alternatives. First, it is macOS-only, excluding Windows and Linux users. Second, it focuses on audio, which may not suit those who prefer visual monitoring. Third, it lacks certain features like token usage tracking or cloud-based persistence. Finally, some users may want a simpler, more lightweight tool or one that integrates with specific agents like GitHub Copilot CLI. Alternatives can address these gaps, offering different platforms, interaction styles, or additional capabilities.

Top Alternatives

1. Vox

Vox is a cross-platform voice interface specifically designed for GitHub Copilot CLI. It works on Windows, macOS, and Linux, making it a versatile choice for Copilot users. Vox is lightweight, pure JavaScript, MIT licensed, and has no telemetry. It provides a reactive visual orb and transcript panel for interactive feedback. However, it lacks Heard's multi-agent awareness, mobile pairing, and intelligent summarization—it reads full replies verbatim. Choose Vox if you're a Copilot CLI user on non-macOS platforms who wants a simple, hands-free voice interface for single sessions.

2. AgentMicro

AgentMicro is a local-first, privacy-focused menu-bar tool for monitoring parallel Codex tasks. It never uploads prompts or code, appealing to users with strict data privacy needs. It offers a lightweight, at-a-glance overview of tasks without requiring Accessibility permissions. However, it is text-based and visual only, lacking voice narration and audio summaries. It also supports only Codex, not Claude Code or Cursor, and doesn't provide intelligent summarization—just raw task state. Choose AgentMicro if you prioritize privacy and prefer a visual, local-first approach for Codex tasks.

3. AgentPeek

AgentPeek provides a visual, glanceable overview of all agent sessions in the Mac notch, with live token usage tracking and rate limit warnings. It allows quick approval of permission prompts via keyboard shortcuts and is a one-time purchase. However, it requires you to stay at your desk and look at the screen, lacking audio summaries and mobile pairing. It doesn't offer project-level summarization or customizable personas. Choose AgentPeek if you want a visual complement to Heard, with token tracking and quick approvals, but don't need hands-free audio.

4. AgentSky

AgentSky is a cloud-based, managed agent environment that runs even when your laptop is closed, offering persistent sessions and multi-channel access via WhatsApp, iMessage, Telegram, Slack, web, API, and CLI. It includes a model router and agent arena for performance comparison. However, it is purely text-based, with no voice narration, and is a paid API service with per-minute and per-token costs. It requires adopting a cloud-hosted agent model, unlike Heard's local integration. Choose AgentSky if you need remote, always-on agents accessible from multiple platforms and don't require audio feedback.

5. Agents Never Sleep

Agents Never Sleep is a lightweight macOS menu bar app that ensures your agents keep running even when the laptop lid is closed. It's a one-time purchase with a 14-day money-back guarantee and no data collection. However, it provides no voice narration, summaries, or alerting—it only prevents sleep. It lacks multi-agent awareness, mobile pairing, and intelligent listening modes. Choose Agents Never Sleep if your primary need is to keep agents running while away, and you already have your own monitoring setup.

How to Choose

When selecting an alternative to Heard, consider your platform, agent compatibility, and interaction preferences. If you're on Windows or Linux and use GitHub Copilot CLI, Vox is a solid choice. For privacy-focused Codex users who prefer visual monitoring, AgentMicro fits well. If you want token tracking and quick approvals while staying at your desk, AgentPeek is ideal. For cloud-based, multi-channel access without voice, AgentSky offers a managed solution. And if you simply need to prevent sleep, Agents Never Sleep is a simple fix. Evaluate whether you need audio summaries, mobile pairing, or project-level summarization—Heard excels in these areas, but alternatives may compensate with other strengths like cross-platform support or visual dashboards. Ultimately, the best choice depends on your workflow, budget, and whether you prioritize hands-free listening or visual oversight.

Alternatives

1. Vox

Vox is a GitHub Copilot CLI extension: run /vox and a reactive listening orb opens in its own window. Speak your turn, hear the agent reply. Voice in, voice out — on Windows, macOS, and Linux.

Pros

+ Cross-platform: works on Windows, macOS, and Linux, whereas Heard is macOS-only.
+ Specifically designed for GitHub Copilot CLI, making it a natural fit for Copilot users.
+ Lightweight, pure JavaScript, no build step, and MIT licensed with no telemetry.
+ Offers a reactive visual orb and transcript panel for a more interactive experience.

Cons

- Limited to GitHub Copilot CLI, while Heard supports Claude Code, Codex, and Cursor.
- Lacks Heard's multi-agent awareness and project-level summarization for parallel sessions.
- No mobile pairing or 'leave the desk' capability; Heard offers phone-based listening and talk-back.
- No listening modes (co-pilot, companion, focus) or persona customization; Vox is simpler.
- Heard provides intelligent summarization and salience routing, whereas Vox reads full replies verbatim.

Choose Vox if you're a GitHub Copilot CLI user on Windows or Linux who wants a simple, hands-free voice interface for single sessions. It's a good lightweight alternative when you don't need multi-agent orchestration or mobile integration.

2. AgentMicro

AgentMicro is a local-first macOS menu-bar companion for supervising parallel Codex Desktop and CLI tasks. It surfaces task state, project, elapsed time, and results at a glance, then opens the matching Codex Desktop task with one click. It observes local metadata only and never uploads prompts, responses, source code, or task history.

Pros

+ AgentMicro is local-first and privacy-focused, never uploading prompts, code, or task history, which may appeal to users with strict data privacy requirements.
+ It provides a lightweight, at-a-glance menu-bar overview of parallel Codex tasks, making it easy to monitor multiple sessions without switching windows.
+ It is free and open source, with no account or Accessibility permission required for base mode, lowering the barrier to entry.

Cons

- AgentMicro is text-based and visual only, lacking Heard's core voice narration and audio summaries, so it cannot be used hands-free or when away from the screen.
- It is limited to Codex tasks only, whereas Heard supports Claude Code, Codex, and Cursor, offering broader agent compatibility.
- AgentMicro does not provide intelligent summarization or prioritization of agent output; it simply surfaces raw task state and results, requiring the user to read and interpret the information themselves.
- It lacks mobile pairing and remote listening capabilities, so users cannot stay connected to their agents while away from their Mac.

Choose AgentMicro over Heard if you primarily use Codex, prefer a purely visual and local-first monitoring approach, and are comfortable reading task updates rather than listening to them. It is ideal for users who prioritize privacy and want a simple, free menu-bar tool to track parallel tasks without voice features.

3. AgentPeek

You're running more coding agents than ever, but you can't keep up with them. That's where AgentPeek comes in. It pulls every session up into your Mac notch, live. Glance up, approve a prompt, watch token usage and manage the entire flow without pausing your YouTube video. All local, all yours.

Pros

+ Provides a visual, glanceable overview of all agent sessions in the Mac notch, which can be more immediate than audio summaries for some users.
+ Offers live token usage tracking and rate limit warnings, which Heard does not mention.
+ Allows quick approval of permission prompts directly from the notch with keyboard shortcuts, which may be faster than voice interaction.
+ One-time purchase instead of a subscription, which may appeal to users who prefer to avoid recurring costs.

Cons

- Requires you to keep looking at the screen, whereas Heard is designed for eyes-free, audio-based monitoring.
- Does not provide spoken summaries or narration, so it's not suitable for users who want to step away from the desk.
- Lacks mobile pairing and voice reply capabilities, which Heard offers.
- No multi-agent summarization at the project level; you see individual sessions rather than a unified story.
- No customizable personas or voice options, which Heard provides.

Choose AgentPeek if you prefer a visual, at-a-glance overview of your agents while staying at your desk, and you want to track token usage and approve prompts quickly without audio. It's a good complement to Heard for users who want both visual and audio monitoring, but not a full replacement for those who need hands-free, eyes-free updates.

4. AgentSky

Managed agent as a service: launch a long-horizon AI agent in one click — Claude Code, Codex, Hermes, or OpenClaw — with full history, managed recovery, and access through WhatsApp, iMessage, Telegram, Slack, web, API developers, and CLI.

Pros

+ AgentSky provides a cloud-based, managed agent environment that runs even when your laptop is closed, offering persistent sessions and recovery from crashes—unlike Heard which is tied to your local macOS session.
+ AgentSky offers multi-channel access (WhatsApp, iMessage, Telegram, Slack, web, API, CLI) so you can interact with agents from any device, whereas Heard's mobile pairing is limited to iOS/Android with a scoped session.
+ AgentSky includes a model router and agent arena for comparing performance, which can help you choose the best agent/model for a task—Heard focuses on narration, not agent selection.

Cons

- AgentSky does not provide any voice narration or audio summaries of agent activity; it is purely text-based via chat channels, so you lose the hands-free, eyes-free listening experience that Heard offers.
- Heard is free and open-source for personal use, while AgentSky is a paid API service with per-minute and per-token costs, which could be more expensive for casual users.
- Heard integrates directly with local agents like Claude Code and Codex on your Mac, giving you real-time spoken updates without needing to move your workflow to the cloud—AgentSky requires you to adopt a cloud-hosted agent model.

Choose AgentSky over Heard if you need to run agents remotely in the cloud with access from multiple messaging platforms and don't require voice narration. It's better for users who want a managed, always-on agent service rather than a local voice layer for their existing terminal workflows.

5. Agents Never Sleep

A macOS menu bar app that keeps your agents AI awake even if with lid closed. No more keeping your laptop half-open or carrying it around in weird ways. Stop this madness 🙅‍♂️, close the lid.

Pros

+ Ensures your agents keep running even when the laptop lid is closed, which is a common need for users who want to step away while agents work.
+ Simple, one-time purchase with a 14-day money-back guarantee, no subscription required.
+ Lightweight and native macOS menu bar app with no data collection.

Cons

- Does not provide any voice narration, summaries, or alerting—it only prevents sleep, so you still have to check the terminal yourself.
- Lacks multi-agent awareness, mobile pairing, or any of Heard's intelligent listening modes.
- Not open source and offers no free tier, unlike Heard's free personal use option.

Choose Agents Never Sleep if your primary need is simply to keep your agents running while the lid is closed, without needing any audio feedback or summaries. It's a complementary tool for users who already have their own monitoring setup but want to ensure agents don't pause.
