TaskbarQuota

Live AI usage, cost, and agent activity in the Windows taskbar.

TaskbarQuota is a native Windows app for people who use several AI coding tools. It detects the provider in your focused app or terminal, then keeps the relevant quota visible beside the system tray. Open the dashboard for usage history, model-level costs, and a live view of local coding agents.

Everything runs on your PC. TaskbarQuota has no account system, cloud backend, or telemetry.

TaskbarQuota supports Windows 10 version 2004 (build 19041) and newer. Windows 11 is recommended.

• Install the signed build from the Microsoft Store.
• Or download the latest x64 or arm64 installer from GitHub Releases.

GitHub installers are currently unsigned, so Windows SmartScreen may ask for confirmation. Choose More info, then Run anyway.

TaskbarQuota places a compact, draggable widget next to the notification area. It shows quota windows, percentages, reset times, credits, or balances depending on the provider.

The widget can:

• follow the active tool automatically;
• keep up to three providers pinned;
• appear on each taskbar in a multi-monitor setup;
• run as a floating always-on-top window instead;
• show bars, percentages, or both, as used or remaining.

Click the widget for a quick flyout. Open the main window to see every provider and change settings.

When an AI desktop app is focused, TaskbarQuota matches its process to a provider. When a terminal is focused, it looks for a running CLI agent such as Codex, Claude Code, OpenCode, Cline, Kimi, Grok, or GitHub Copilot.

Switching between an editor and a terminal updates the widget automatically. TaskbarQuota also follows provider changes inside supported hosts such as OpenCode, Cline, Synara, and T3 Code.

A separate activity widget shows what local coding agents are doing. Sessions can appear as working, waiting, idle, completed, or failed, and the flyout lets you jump between active sessions.

Activity is read from local processes and session data for Codex, Claude, OpenCode, Cline, Kimi, Grok, Antigravity, GitHub Copilot, and ZCode. Completed items expire automatically. You can hide the activity widget or disable monitoring completely.

The Cost page combines locally available usage across providers. It includes:

• spend and token totals for today, the last 7 days, and the last 30 days;
• daily history and provider comparisons;
• per-model token and cost breakdowns;
• reported costs when available, with estimates from bundled pricing data otherwise;
• shareable summary cards.

Cost coverage depends on the data exposed by each provider. Codex, Claude, Grok, OpenCode, Cline, and Z.ai are read from local logs or databases. Cursor token history and reported API-rate cost come from its authenticated account usage events. Antigravity token history comes from the recorded counters in its local conversation databases; its dollar cost remains an API-rate estimate because Antigravity does not record billed cost. TaskbarQuota leaves unknown models unpriced instead of inventing a cost.

The dashboard shows all enabled providers, their current plan, quota windows, reset times, balances, and recent history. TaskbarQuota can start with Windows and notify you when quota thresholds are crossed or Codex reset credits are close to expiring.

Quota replenishment notifications are enabled by default and remain independent from the optional Warning and Critical threshold alerts. They notify when a live percentage-based window gains at least 10 percentage points of available quota, including partial replenishments and readings that reach 99% after a reset has already been used. Primary, Secondary, Model, Monthly, and named extra windows are tracked separately, and multiple replenished windows from the same provider are grouped into one notification.

The first live reading after launch or after re-enabling the option establishes a baseline without notifying. A separate, disabled-by-default Changes since last session option can compare the first live reading after startup with TaskbarQuota's last confirmed live observation. This can report a replenishment that happened while the app or PC was off, but only after TaskbarQuota starts and refreshes that provider.

Cross-session comparison requires the same provider and account identity, stable window metadata, and an observation no more than 35 days old. Missing or changing identity, stale state, cached or restored snapshots, failures, and changed window definitions establish a new baseline silently. The Consumed/Remaining display preference does not affect detection.

Notifications use the coordinator's existing provider refreshes. They work with the dashboard closed and the widget hidden while TaskbarQuota is running and receiving live observations for that provider. The feature adds no polling, timer, network request, telemetry, or remote notification service.

TaskbarQuota reuses credentials already stored by supported tools when possible. If automatic detection fails, use Fix on the provider card to enter the required token or cookie manually.

• Usage requests go directly from your PC to the provider.
• Agent activity and prompt-derived session titles stay on your PC.
• TaskbarQuota does not collect telemetry or send data to a TaskbarQuota server.
• Diagnostics are written only to %TEMP%\taskbarquota.log.
• Automatic browser cookies are read in memory. Credentials entered manually are stored in plain JSON at %LOCALAPPDATA%\TaskbarQuota\credentials.json, so keep that file private.
• Optional cross-session replenishment state is stored locally in quota-replenishment-state.json. It contains percentage-window metadata, timestamps, and a one-way identity hash, never the plaintext account identifier. Disabling either replenishment notifications or the cross-session option clears it.

Disable Monitoring in the activity flyout to stop local process and session inspection and clear retained activity from memory.

Modern Chromium browsers protect cookies with App-Bound Encryption, so TaskbarQuota may not be able to read an OpenCode session from recent versions of Chrome, Edge, or Brave. Firefox-based browsers are supported, or you can paste a copied OpenCode request into the provider's Fix dialog. TaskbarQuota accepts either a full cURL command or its Cookie header.

Cookie headers are session credentials. Do not paste them into issues or public chat.

Requirements:

• Windows 10 build 19041 or newer
• .NET SDK 10
• Windows App SDK and WinUI 3 tooling

# Build
dotnet build src/TaskbarQuota.App/TaskbarQuota.App.csproj -c Debug -p:Platform=x64

# Run
dotnet run --project src/TaskbarQuota.App/TaskbarQuota.App.csproj

# Test
dotnet test tests/TaskbarQuota.Tests/TaskbarQuota.Tests.csproj

The app is a self-contained WinUI 3 build. It does not require a separate backend.
