Every Rust module under src/ that previously contained upstream-derivative
code has been replaced by a from-scratch implementation:
diag/ log + simplelog file appender (was: diagnose.rs)
os/ color, dpi, registry, string, theme (was: theme.rs, native_interop.rs)
net/ WinHTTP-based HTTP client (was: ureq + native-tls)
i18n/ TOML-embedded locale tables (was: localization/*.rs)
usage/ trait UsageProvider + ClaudeProvider + ChatGptProvider + refresh
orchestrator + registry (was: poller.rs, models.rs)
creds/ trait CredentialSource + local/WSL/Codex impls (was: poller.rs)
tray/ stateless tray manager + tiny-skia anti-aliased badge renderer
(was: tray_icon.rs)
update/ release fetch + inline cmd /c handoff installer
(was: updater.rs's helper-exe pattern)
Application files (app.rs, bubble.rs, panel.rs, settings.rs) migrated to
the new modules. main.rs declares only the new modules.
NOTICE deleted; LICENSE is plain Apache-2.0; README updated to credit
inspiration rather than claim derivation. Cargo.toml drops ureq + native-tls
+ winres in favour of log + simplelog + thiserror + toml + tiny-skia +
embed-resource. Build script swapped to embed-resource via res/icon.rc.
External contracts preserved unchanged: Anthropic + ChatGPT endpoints and
headers, ~/.claude/.credentials.json + Codex auth.json paths, WSL bridging
via wsl.exe, CLI-driven token refresh, GitHub Releases JSON shape, Windows
registry path for startup, single-instance mutex name.

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
Until packaged binaries are published, build from source:
git clone https://github.com/<your-fork>/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, update frequency, language, "Start with Windows", 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.
