User feedback on v0.1.13: design works, but the 5h percent glyph in the
head crowds the ring at small bubble sizes (the "100%" string was wider
than the ring's inner clear at MIN_BUBBLE_SIZE).
Two parallel UI/UX reviewers converged on:
- big_font_px ratio: head_diameter × 26/100 (was 35/100), floor 11
- small_font_px ratio: big × 55/100 (was 45/100), floor 9
- head_pad: 4 logical px (was 6) — recovers 4px
of inner clear at small sizes
- ring_stroke_w: clamped to [2, 4] (was floor 2 only)
- label/glyph gap: big × 15/100, floor 2 (was implicit 0)
- tail_bar_h: 5 logical px (was 6) — restores
proportion against the 3-px head ring stroke
Worked example at MIN_BUBBLE_SIZE=140 (head_diameter=47):
before: "100%" glyph ≈ 32px wide vs 28px ring inner — overflow
after: "100%" glyph ≈ 23px wide vs 32px ring inner — comfortable
Worked example at MAX_BUBBLE_SIZE=360 (head_diameter=138):
glyph ≈ 70px wide in 124px inner clear (~57%) — confident not crowding
Deliberately not applying:
- drop "7d" label (one reviewer wanted it): rejected — symmetry with
"5h" matters for self-explanation at a glance, and the ~14px cost is
acceptable
- head_diameter bump to canvas_h × 1.08: rejected — only useful coupled
with the label drop
Build clean.
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.
