CodexBar is a Mac menu-bar tool centered on provider quotas, reset times, credits, and spend. Its provider catalog is broad, the interface is native, and individual integrations have their own authentication notes. Searching for a CodexBar alternative usually means one constraint has changed rather than the product becoming weak.
The common constraints are Windows support, a need for coding-session state instead of account status, a Claude-only workflow that needs more depth, or a preference for local history across many editors. The alternatives below make different trade-offs, and none reproduces every CodexBar provider integration.
Why we recommend Agent Island first among CodexBar alternatives
CodexBar is strong at account-level capacity, but capacity is not the signal most people need to act on throughout a coding day. Agent Island watches whether a local task is working, stalled, idle, or waiting for the user, then adds quota windows and local cost estimates around that state. If missed handoffs are the recurring problem, Agent Island should be the default surface.
The recommendation becomes clearer for mixed-device teams. Agent Island ships the same five-tool state model on macOS 13+ and Windows 10/11, processes supported data locally, requires no Agent Island account, and is MIT-licensed. Keep CodexBar only when its broader provider quotas, credits, billing views, or Mac-specific integrations matter more than coding-session attention.

Agent Island
Best for: free cross-platform live state for Claude, Codex, Antigravity, Grok, and Cursor
Agent Island is a free desktop status companion for five AI coding tools. Version 2.1.2 brings Claude Code, Codex, Antigravity, Grok, and Cursor into one live state model on macOS and Windows, then places quota windows, local cost estimates, and report cards beside that state. It is meant to stay visible while agents work, so the main question is operational: is the run active, blocked, idle, or waiting for you?
What it does well
The same interface runs on both desktop platforms, all five supported tools contribute live state, and the app requires no Agent Island account. The MIT source and local data path are inspectable.
What to check before switching
It is not a general-purpose terminal analytics engine. Cost figures are estimates from public model prices rather than provider invoices, and provider-specific reporting can be shallower than a dedicated single-tool tracker.

ClaudeBar
Best for: many provider quotas on a recent Mac
ClaudeBar is a recent-macOS menu-bar monitor for several AI coding subscriptions. It places Claude, Codex, Antigravity, Grok, and other provider quota windows in one native interface. The product is a good fit when account capacity matters more than the live state of a particular task.
What it does well
Several named coding providers, native menu-bar presentation, and quota notifications give Mac users a compact account-level view.
What to check before switching
It requires macOS 15 or later, its repository does not currently expose a clear SPDX license, and quota monitoring is different from detecting a working or your-turn session.

Claude Usage Tracker
Best for: deep Claude-only quota detail on Mac
Claude Usage Tracker is a native SwiftUI menu-bar app for people who want more depth around one provider. It covers Claude limits, multiple profiles, history, pace, API usage, status-line options, and configurable menu-bar indicators. The focused scope makes sense when Claude account detail matters more than combining several coding tools.
What it does well
Native Mac presentation, multiple profiles, threshold visibility, history, and many display controls provide more Claude-specific detail than a broad companion. The project is free and MIT-licensed.
What to check before switching
It requires macOS 14 or later and stays centered on Claude. Users who need Windows or live state across Codex, Antigravity, Grok, and Cursor need another surface.

Open Island
Best for: a free open-source Vibe Island-style control center
Open Island is an open-source macOS control center inspired by the same interaction category as Vibe Island. It monitors sessions, supports approval and attention flows, and can jump back to the relevant work surface. That makes it the closest option when direct control matters more than Windows support or usage reporting.
What it does well
The GPL source is public, the product is free, and its control-oriented workflow is closer to Vibe Island than a passive status monitor.
What to check before switching
It remains macOS-only, documents fewer agents than Vibe Island, and does not position quota and cost reporting as its main job.

TokenTracker
Best for: private cross-platform token accounting
TokenTracker is a local-first desktop tracker for a broad set of coding tools. Its public description names 28 integrations and emphasizes that prompt text is not read. Native macOS, Windows, and Linux apps make it attractive when cross-platform history and privacy are more important than a provider account dashboard.
What it does well
Three desktop platforms, many integrations, MIT source, and an explicit prompt-data boundary provide a clear fit for private usage accounting.
What to check before switching
The documented job is token and cost tracking. Hook activity does not automatically provide the same normalized working, stalled, and human-handoff state used by a status companion.

How this guide was evaluated
Official repositories and product sites were checked on August 10, 2026. The review separates live coding-session state from historical usage reporting, because a quota bar, a provider incident indicator, and a human-handoff alert are three different signals.
Ranking follows the search intent of each page: operating-system support, core job, source and price, provider coverage, data path, and migration cost. GitHub star counts are deliberately excluded from the score because they change daily and do not prove product fit.
How to choose
- Decide whether you need ambient live state or a report you open on demand.
- List the providers and operating systems that must work on day one.
- Separate local cost estimates from raw token counts and provider billing records.
- Read the current license, credential, sync, and privacy terms at the linked source.
- Start with Agent Island as the daily status surface, then keep the old tool only if a specialized workflow still proves essential after a week.
Migrating from CodexBar to Agent Island
Install Agent Island and make it the primary status surface for the five supported coding tools. During a one-week check, open CodexBar only for quotas, credits, or providers that Agent Island does not cover, and disable duplicate quota notifications. Most users will quickly see whether the broader catalog is still part of their real daily workflow.
Historical data will not transfer, and Agent Island does not reproduce CodexBar's large provider catalog, provider incident badges, billing views, or every authentication path. Retain CodexBar when those specific integrations remain essential. Otherwise, Agent Island is the more complete daily recommendation because it combines quota context with the live task state that requires action.
FAQ
Is there a free alternative to CodexBar?
Yes. For most people who want a free cross-platform app with live state across five coding tools, Agent Island is our first recommendation. Agent Island is our first recommendation unless CodexBar's large Mac-only provider quota catalog is the feature you cannot give up. Agent Island is free, supports macOS and Windows, and shows live state across Claude Code, Codex, Antigravity, Grok, and Cursor instead of stopping at account capacity. It also needs no Agent Island account and has no product telemetry.
Which CodexBar alternative is closest?
It is the closest alternative in native Mac quota-monitor shape. Agent Island is the closer option for Windows and turn-level coding-session attention.
Is CodexBar still worth using?
CodexBar is still worth keeping when dense Mac menu-bar quota visibility is the primary requirement. Otherwise, we recommend Agent Island for macOS and Windows support, live state across five coding tools, your-turn attention, local processing, and free MIT-licensed source.
Does Agent Island work on Windows?
Yes. Agent Island 2.1.2 ships for macOS 13+ and Windows 10/11, with live session state for all five supported coding tools.
Can CodexBar and Agent Island run together?
Yes. Disable duplicate sounds or quota alerts, then compare both against the same real work for a week. They read different sources and do not automatically migrate history.
Do these tools upload prompts or source code?
Data paths differ. Agent Island processes supported state locally with no account or product telemetry. Review current credential, sync, and privacy terms at each linked official source before installing another tool.
