Rust's std::process::Command escapes inner double quotes as \" when wrapping the args(["/c", &cmd]) array. cmd.exe does not understand the \" escape, so the swap-and-restart command got mangled: `start "" "PATH"` arrived as `start \"\" \"PATH\"`, which the cmd parser collapsed into `start \ PATH` — producing the "Windows cannot find '\'" dialog and aborting the update. Switching to raw_arg lets us hand cmd.exe the literal command line it expects. The two quote characters cmd needs to keep are the outer pair wrapping the whole /c argument; cmd's "more than two quotes, special chars present" branch then preserves the inner path quotes intact. Bumps version to 0.1.2 since this is the first updater fix that ships through the updater itself for any future v0.1.2+ user.
Claude Code Usage Bubble
A floating, draggable circular bubble that shows your Claude Code and/or Codex usage on Windows — inspired by the floating "memory boost ball" UX of 360 Security and IObit Advanced SystemCare.
Drop it anywhere on screen, drag it around, snap it to a monitor edge, left-click for a panel with both your 5-hour and 7-day windows, right-click for the menu.
Acknowledgements
Inspired by CodeZeno/Claude-Code-Usage-Monitor, which solves the same "how close am I to the Claude Code limit?" problem with a horizontal taskbar widget. This project takes the UX in a different direction — a floating, draggable circular bubble that the user can place anywhere on screen — and is a clean-room implementation: the HTTP client, provider polling, credential discovery, localisation, tray rendering, and self-updater are all written from scratch against the same public APIs (Anthropic, ChatGPT, GitHub Releases).
What you get
- A circular floating bubble showing your current 5-hour Claude Code or Codex usage as a percentage and a colored progress ring
- Drag anywhere — the bubble snaps to monitor work-area edges when released
- Resize with
Ctrl + MouseWheelon the bubble (32–128 pixels) - Left-click the bubble for an expanded panel with both 5h and 7d bars plus reset countdowns
- Right-click for refresh, displayed models, update frequency, language, startup, updates, exit
- Optional system tray icons (one per enabled model)
- Auto-hide when a fullscreen app is in the foreground (games, video, presentations) — reappears when you leave fullscreen
Who this is for
Windows 10/11 users who already have Claude Code (CLI or App) installed and signed in. Codex support is optional — install and sign in to the Codex CLI, then enable Codex from the right-click Models menu.
If you use Claude Code through WSL, that is supported too. The monitor can read your Claude Code credentials from Windows or from your WSL environment.
Requirements
- Windows 10 or Windows 11
- Claude Code (CLI or App) installed and authenticated
- Optional: Codex CLI installed and authenticated, if you want Codex usage
Install
Download the latest release
Grab claude-code-usage-bubble.exe from the
Releases page.
Put it anywhere on disk (e.g. %LOCALAPPDATA%\ClaudeCodeUsageBubble\) and
run it. The app self-updates from the same Releases feed.
First-run note: the binary is unsigned, so SmartScreen will show "Windows protected your PC". Click More info → Run anyway. Code signing is on the roadmap.
Build from source
git clone https://github.com/tiennm99/claude-code-usage-bubble
cd claude-code-usage-bubble
cargo build --release
The binary lands at target/release/claude-code-usage-bubble.exe.
Use
Run claude-code-usage-bubble.exe. The bubble appears near the bottom-right
corner of your primary monitor on first launch. Drag it where you want it,
release to snap to the nearest edge if you let go close to one.
- Left-click the bubble to open the expanded panel (5h + 7d + countdowns)
- Right-click for refresh, models, refresh frequency, language, "Start with Windows", auto-update check (Disabled / Hourly / Daily / Weekly), manual "Check for updates", exit
- Drag anywhere — it floats on top of all other windows
- Ctrl + MouseWheel on the bubble to resize it
- Tray icon (if enabled): left-click toggles the bubble visibility, right-click opens the same menu
Models
Use the right-click Models menu to choose what is shown:
- Claude Code is enabled by default
- Codex can be enabled alongside Claude Code or shown by itself
When both models are shown, each gets its own bubble that you can position independently.
Diagnostics
claude-code-usage-bubble.exe --diagnose
This writes a log file to:
%TEMP%\claude-code-usage-bubble.log
Settings are saved to:
%APPDATA%\ClaudeCodeUsageBubble\settings.json
Privacy and security
What the app reads:
- Your local Claude Code OAuth credentials from
~/.claude/.credentials.json - If needed, the same credentials file inside an installed WSL distro
- If Codex is enabled, your local Codex credentials from
$CODEX_HOME/auth.jsonor~/.codex/auth.json
What the app sends over the network:
- Requests to Anthropic's Claude endpoints to read your usage
- Requests to ChatGPT's Codex usage endpoint, if Codex is enabled
- Requests to GitHub only if you use the app's update-check feature
What the app stores locally:
- Bubble position(s) per model
- Bubble size
- Polling frequency
- Language preference
- Last update check time
- Displayed model preferences
What it does not do: send credentials to any third-party server, run a
backend service, collect analytics, upload your project files, or write to
your Codex auth.json directly.
