CodexBar: A Mac Menu‑Bar App to Monitor AI Usage (15.5k Stars)

When using multiple AI coding assistants such as OpenAI Codex, Claude, Cursor, or GitHub Copilot, developers often have to check each provider’s quota separately, which can be tedious.

CodexBar solves this “AI‑usage anxiety” by adding a small icon to the macOS menu bar. After installation the icon shows the remaining quota for every configured provider at a glance.

The app supports 53 AI providers—including OpenAI, Claude (Anthropic), Cursor, GitHub Copilot, Gemini, Grok, DeepSeek, Kimi, Doubao, MiniMax, Ollama, Perplexity, OpenRouter, ElevenLabs, and AWS Bedrock. Each provider appears as an individual menu‑bar icon, and a “merged icon” mode can collapse them into a single entry.

For each provider CodexBar displays the current usage window (session, weekly, or monthly), the amount of credit left, and a countdown to the next reset. It also shows monthly spending and credit balance for OpenAI admin accounts, and polls provider status pages to flag service outages directly on the icon.

Security‑wise, CodexBar does not store passwords. It reuses existing authentication data—OAuth tokens, browser cookies, API keys, or local CLI credentials—so no new credentials are required. Different providers use different mechanisms (e.g., OpenAI via OAuth or CLI session, Claude via OAuth or cookies, Cursor via browser cookies, Copilot via GitHub Device Flow, DeepSeek via API key, Gemini via OAuth CLI credentials).

Installation is a single Homebrew command: brew install --cask codexbar Alternatively, the binary can be downloaded from the GitHub Releases page. The app requires macOS 14 (Sonoma) or later. After installing, users enable providers in Settings → Providers.

CodexBar also includes a built‑in CLI that lets users configure providers, view usage, and integrate the data into CI scripts; the CLI works on Linux as well.

15.5k Stars, zero‑configuration, support for 53 providers—CodexBar deserves a spot in your menu bar.
