Every AI coding limit, in your Windows tray. CodexBar-Windows is a native Windows version of CodexBar: it shows your OpenAI Codex session (5-hour) and weekly usage windows with reset countdowns, your Claude Code token totals, and your OpenRouter credit balance — in a lightweight system-tray icon and popup menu, with a full command line for scripting. No account logins, no telemetry, no external runtimes: it reads the log files Codex and Claude Code already write on your PC, plus OpenRouter's own key-usage endpoint with a key you store encrypted on your machine.
- Codex — the real rate-limit windows from the Codex CLI's local session logs: session (5h) and weekly used percent, reset times, plan name, and total tokens.
- Claude Code — real token totals from Claude Code's local transcripts: today, last 7 days, last 30 days. (Claude Code does not store account limit percentages locally, so none are invented.)
- Gemini — Pro / Flash / Flash Lite quotas and your plan, through the Gemini CLI's own local sign-in (no key to store).
- OpenRouter — credit usage and remaining balance for your API key,
from OpenRouter's
auth/keyendpoint. - DeepSeek — account balances (total, granted, topped-up) for your API key, from DeepSeek's balance endpoint.
The tray warns you once when any usage window crosses 90%.
When the network is down, the last known numbers stay on screen with an "offline" note instead of going blank.

Download from GitHub Releases:
CodexBar-Windows-v<version>-x64-Setup.exe— installerCodexBar-Windows-v<version>-x64-Portable.zip— unzip anywhere and run
The program is a single self-contained executable. It writes only to a
data/ folder beside the executable, so the portable copy can live on a
USB stick. Binaries are unsigned (no code-signing certificate); Windows
SmartScreen may ask you to confirm the first run.
Double-click codexbar-windows.exe and it settles into the tray and
opens the usage detail window. The tray icon shows your busiest
window's percent as a number (green, amber at 70%, red at 90%); hover for a summary,
click for the full breakdown, Refresh, and Quit. It refreshes every 15
minutes (changeable) and keeps a bounded history of past readings in
data/history.json.
Everything the tray does is also a command:
codexbar-windows status last collected numbers
codexbar-windows refresh collect fresh numbers now
codexbar-windows refresh --json same, machine-readable
codexbar-windows history past snapshots
codexbar-windows report day-by-day summary from history
codexbar-windows details open the usage detail window (cards)
codexbar-windows breakdown per-model tokens + cost estimates
codexbar-windows set-key openrouter
store a provider key (read from stdin,
encrypted with Windows DPAPI); openai
and anthropic take Admin keys for their
organization usage endpoints
codexbar-windows config refresh 30 set the refresh interval (minutes)
codexbar-windows settings open the settings window (Windows)
codexbar-windows settings --warn 85 set the warning threshold
codexbar-windows --help full command list, works offline
- Local logs are read, never modified or uploaded.
- The OpenRouter key is encrypted with Windows DPAPI (current-user scope)
and only ever sent to
openrouter.ai. - There is no telemetry, no analytics, and no other network traffic.
Screenshots will be added from real runs on a Windows machine.
