Claude Status Bar

Your Claude Code usage, at a glance. 5h / 7d rate-limit bars, reset countdowns, model, context window, and prompt-cache freshness — inline in Claude Code's status line, or a floating HUD on the desktop app.

English · 简体中文 · Install · Documentation

Important

macOS standalone users should upgrade to v3.32.5 now. Older onefile releases could leave a new ~11 MB PyInstaller _MEI* runtime directory on every one-second refresh that was killed during startup. Re-running the installer switches to an onedir bundle and safely removes inactive leftovers: curl -fsSL https://raw.githubusercontent.com/leeguooooo/claude-code-usage-bar/main/install.sh | bash

Claude Code tells you almost nothing about where you stand against your rate limits. claude-statusbar puts the numbers that matter on one quiet line at the bottom of your terminal — so you never switch context to a separate window to answer "how much have I got left, and when does it reset?"

Features

• Official 5h / 7d usage — the same rate-limit numbers Claude Code enforces, with reset countdowns and end-of-window projections (→NN%), not a local guess.
• Model & context window — current model and how full the context is (Opus 4.8 · 350k/1M).
• Prompt-cache countdown — see how long your cache stays warm (cache 4m23s) so you know when the next turn pays full price.
• Cost & balance — optional per-session cost, or live relay/API balance in no-quota setups.
• Two surfaces — inline statusLine in the terminal, or an always-on-top floating HUD for the Claude desktop app (macOS).
• 3 styles × 9 themes — switch the whole look with one command: battery-bar, capsule, or hairline.
• Fast mode — release bundles use a native cache reader and two persistent render workers. Git and network collection run on separate, bounded background queues.
• More when you want it — git branch & diff stats, session activity, AgentParty/Codex presence, IELTS writing-coach progress — each opt-in.
• Zero-dependency install — a single prebuilt binary (no Python needed) or a pip package. Auto-updates.

Refresh and caching

Display ticks stay at one second; data collection follows its own schedule:

Data	Refresh policy
Countdown and elapsed time	Recomputed from timestamps on each render
Context, model and session cost	Latest statusLine input
Transcript activity	Reuse unchanged snapshots; read only appended tail bytes, with a bounded rebuild after replacement or truncation
Git dirty / ahead / behind	Shared per worktree, 30-second cache, one refresh at a time
Configuration and language progress	Reload when file metadata changes
Balance and optional model caps	Shared per account, background refresh; failures are cached

The native reader is included in macOS arm64 and Linux x86_64 release archives. Pip/uv installations continue to use the Python client. Existing cs render commands keep working; binary upgrades take effect on the next invocation.

Optional model-specific weekly limits can be enabled with cs config set show_per_model true. This explicitly enables read-only OAuth credential access (~/.claude/.credentials.json, or the macOS login Keychain) and background requests to Anthropic's undocumented usage endpoint. No token is logged or stored in a cache. Requests are account-scoped, cached for five minutes, and disabled by default; unsupported responses hide the segment. Relay/no-quota sessions never request these limits. The segment appears on its own line below the main usage row, using the same battery and projection.

For source builds, wrap the PyInstaller bundle before packaging:

pyinstaller packaging/cs.spec --noconfirm
mv dist/cs/cs dist/cs/cs-python
go build -trimpath -ldflags='-s -w' -o dist/cs/cs packaging/native/main.go
python scripts/benchmark_native.py dist/cs/cs
python scripts/benchmark_daemon.py dist/cs/cs

Both benchmarks use temporary fixtures, not live sessions or credentials. The first checks the cache-hit CPU budget; the second exercises 16 concurrent sessions, warm-cache routing, worker count, Git deduplication and freshness. The daemon also writes aggregate timing and worker counters to ~/.cache/claude-statusbar/scheduler.json (no payloads or tokens).

Claude Code (terminal)

One line — no Python, no pip. Downloads a prebuilt standalone binary for your platform (macOS Apple Silicon, Linux x86_64) and wires up the status line:

curl -fsSL https://raw.githubusercontent.com/leeguooooo/claude-code-usage-bar/main/install.sh | bash

_{Security-conscious? Download and read it first — the header lists exactly what it touches. On platforms without a prebuilt binary it falls back to pip.}

On macOS this one line does everything — it wires the terminal statusLine and, if the Claude desktop app is installed, registers the floating desktop HUD to auto-start on login. The macOS binary bundles the HUD, so there's no separate pip install '[hud]' and no extra config.

Prefer pip / uv, or want the desktop HUD extra? Install the Python package:

pip install claude-statusbar     # or: uv tool install / pipx install
cs --setup                       # wires the statusLine hook + installs the skill

Restart Claude Code and the bar appears at the bottom. Other paths (skill-only, plugin marketplace, Codex/AgentParty bridge) are in the install guide.

Deep dive: Is that cache 4m23s line actually accurate? — how the prompt-cache countdown is computed

Claude desktop app (macOS) — cs hud

The desktop app has no status line, so cs hud adds an always-on-top floating panel with the same official 5h / 7d usage (sampled by the desktop app itself, not an estimate) and your active AgentParty channels.

If you used the curl … install.sh | bash one-liner above, the HUD is already installed — the macOS binary bundles it and the installer auto-registers it when the desktop app is present. The commands below are only for a manual/pip setup:

pip install 'claude-statusbar[hud]'   # adds PyObjC (macOS GUI deps)
cs hud install                        # launchd: auto-start on login + keep-alive

Collapsed pill → click to expand → drag anywhere; it hides when the desktop app isn't open. Full details in the Desktop HUD guide.

What it shows

The default bar — classic style, graphite theme:

At a full refresh it can render up to three lines, each segment optional:

Line	Segments
Usage	5h / 7d rate-limit bars, reset countdowns, end-of-window projections (→NN%), model & context window, prompt-cache countdown, optional session cost or relay balance
Project	git worktree marker (⑂ name (3) / ⑂ trunk (3) with the repo's worktree total, its own hue, leads the line), project name, git branch, session +/− lines, duration, version
Mode	session effort / thinking / fast / style

Every icon, color threshold, and toggle is documented in the segment reference. Nine themes and three styles are in styles & themes.

Documentation

Guide	What's inside
Install	Binary, PyPI, one-shot installer, skill-only, plugin, Codex bridge
What it shows	Full per-segment reference table
Styles & themes	3 styles × 9 themes, previews, slash commands
Configuration	Config file, all show_* keys, env vars, JSON output, CLI cheatsheet
Desktop HUD (cs hud)	macOS floating panel for the Claude desktop app
Fast mode (daemon)	Sub-1% CPU daemon, launchd / systemd auto-start
No-quota mode	Relay / Bedrock / Vertex layout, context battery, balance
AgentParty / Codex bridge	Local workspace-presence line
Cache countdown	Data source + how cache 4m23s is computed
Troubleshooting	cs doctor, common problems, upgrading

Comparison

There are a few good Claude Code usage monitors. They solve overlapping but distinct problems — pick the one that matches where you want the information.

Tool	Lives in	Optimized for
claude-statusbar (cs)	Claude Code's statusLine (one line at the bottom)	Glanceable while you work; zero context-switching
ccusage	Standalone TUI in a separate terminal window	Long-form usage analytics, cost breakdowns over weeks
Claude Code Usage Monitor	Standalone TUI with predictive burn-rate	Real-time burn-rate forecast for paid plans

cs is intentionally one line of color and one decision per second. If you want a dashboard with charts, daily/weekly aggregates, and burn-rate prediction, run a TUI in a side pane. The two coexist nicely.

Integrations

prompt-language-coach — install the plugin to track IELTS band progress. The bar then shows your writing level and trend automatically (no config; appears when ~/.claude/language-progress.json exists):
