CodexBar is one of the strongest native Mac choices for Codex and Claude quota visibility. A switch makes sense when Windows support matters, when the workflow now includes Gemini, Grok, or Cursor, or when usage numbers alone do not answer whether an agent is working or waiting. Some users instead want even deeper Claude account pacing or a notch control surface with approvals. Those are different jobs, so the closest replacement changes with the job.
1. ClaudeBar
Best for: the closest practical replacement for CodexBar on its strongest dimension
ClaudeBar is a native macOS quota monitor with a much broader provider list than its name suggests. It reads installed CLI tools and provider-specific sources, then shows session, weekly, model, or credit windows in the menu bar. It is a direct fit for users who care about limits across many providers but do not need Windows.
Strengths
Wide quota-provider coverage, native themes, system notifications, Homebrew installation, and active documentation.
Trade-offs
It requires macOS 15 or later. Its alerts concern quota thresholds rather than the exact moment an agent needs a human response.

2. Claude Usage Tracker
Best for: quota and account usage
Claude Usage Tracker is a native Swift and SwiftUI menu-bar app for Claude account limits. It includes profile support, usage history, pace indicators, status-line integration, and API cost views. Its depth makes sense for someone whose daily work is mostly Claude and who wants account pacing close at hand.
Strengths
Native Mac interface, detailed Claude quota pacing, profiles, history, notifications, and Homebrew installation.
Trade-offs
It requires macOS 14 or later and stays centered on Claude. Some modes use Claude credentials or a manually configured session key, so readers should review that setup before installing.

3. Agent Island
Best for: live for claude, codex, gemini, and grok; cursor usage only
Agent Island is a desktop status companion rather than a report you invoke. It keeps supported agent state, quota windows, local cost estimates, and report cards in one place. Claude, Codex, Gemini, and Grok contribute live state; Cursor contributes billing-cycle usage and plan data only.
Strengths
Cross-platform ambient status, a shared five-provider Usage view, inspectable MIT source, and no Agent Island account or telemetry.
Trade-offs
Cursor has no live session state. Gemini reports working or idle without turn-boundary alerts. Cost figures are estimates from public per-token prices, not billing records, and the project is smaller than the largest tools in this list.

4. Open Island
Best for: live session status
Open Island is a native, local-first notch and top-bar control surface for AI coding agents. It documents ten agents, exact jump-back across many terminals and IDEs, permission approvals, and session tracking. For someone leaving Vibe Island because of price or source access, it is the most direct conceptual replacement.
Strengths
Free GPL source, direct approvals, exact terminal or IDE jump-back, broad Mac agent support, and Homebrew installation.
Trade-offs
It is macOS-only and is designed around a notch or top-bar control surface. Its workflow is more intervention-heavy than a simple status companion.

5. TokenTracker
Best for: usage activity and hooks
TokenTracker combines a local usage dashboard with native tray apps, widgets, achievements, and a desktop pet. It documents 29 coding tools and runs on macOS, Windows, and Linux. The extra presentation layers make it a better fit than a sparse CLI for people who want usage to remain visible throughout the day.
Strengths
Very broad tool coverage, three desktop platforms, local-first setup, dashboard depth, and native widgets.
Trade-offs
Its richest surfaces focus on token activity, cost, and gamification. Readers seeking a restrained working, stalled, and your-turn indicator may find the scope larger than necessary.

|---|---|---|---|---|---|---|---|---|
| ClaudeBar | Public repository; verify current license file; Free | macOS 15+ | Claude, Codex, Gemini, Grok, and additional providers | Quota monitoring | Warning and critical quota notifications | Provider-dependent quota views | Uses installed provider CLIs or documented credentials | Homebrew cask or GitHub Releases |
| Claude Usage Tracker | MIT; Free | macOS 14+ | Claude | Quota and account usage | Usage threshold notifications | API cost tracking documented | Uses Claude Code OAuth or a configured Claude session key | Homebrew cask or GitHub Releases |
| Agent Island | MIT; Free | macOS, Windows | Claude, Codex, Gemini, Grok, Cursor | Live for Claude, Codex, Gemini, and Grok; Cursor usage only | Your-turn alerts where the provider exposes that boundary | Local estimates | Local; no account or telemetry | GitHub Releases |
| Open Island | GPL-3.0; Free | macOS | 10 agents documented | Live session status | Permission and attention flows are documented | Usage tracking for supported integrations | Local-first | Homebrew cask |
| TokenTracker | MIT; Free | macOS, Windows, Linux | 29 AI coding tools documented | Usage activity and hooks | Not documented as a shared your-turn state layer | Token and cost dashboard | Local-first; no cloud account or API keys claimed | npx, native downloads, or Homebrew |
How to choose
Start with the interface you will keep open. An ambient menu-bar app reduces checking; a CLI gives precise filters on request. Decide whether one provider deserves deep treatment or several agents need one view. Inspect the license and data path, confirm operating-system support, and separate local estimates from raw token counts or billing records.
- Do you want ambient status or an on-demand report?
- Is one agent enough, or must several providers share one view?
- Do you need inspectable source and a strictly local data path?
- Must the same workflow run on Windows as well as macOS?
- Are estimates useful, or do you need a specific raw-count export?
Migrating from CodexBar to Agent Island
Download Agent Island for macOS or Windows and run it beside CodexBar for several work sessions. Codex and Claude quota habits map to the shared Usage view, while working, stalled, and your-turn cues move into the Island surface. Profiles and every CodexBar status-line customization do not carry over. Keep CodexBar if those Mac-specific quota controls are central; choose Agent Island when cross-platform state and a five-provider overview remove more friction.

FAQ
Is there a free alternative to CodexBar?
Yes. The open-source entries here are free. Pick by job: terminal reporting, quota pacing, or ambient desktop status.
What is the best CodexBar alternative for macOS?
Choose a native menu-bar or notch app for ambient visibility. Choose a CLI or dashboard for detailed historical queries.
Can I run CodexBar and Agent Island together?
Yes. Disable duplicate notifications, compare the same sessions, and remove one only after its unique features are unnecessary.
Does CodexBar support Codex, Gemini, or Grok?
Check the linked official documentation for the current provider list. This page does not infer undocumented support.
Which alternative works on Windows?
Agent Island and the cross-platform entries marked in the table have documented Windows routes. Mac-native apps do not.
Do these tools upload prompts or source code?
Data paths differ. Read the linked source and current privacy terms before granting credentials or optional sharing permissions.
