Claude Code Usage & Cost Stats

Claude Code usage at a glance, right in the VS Code status bar:

• Status bar: live 5-hour and 7-day (weekly) rate-limit utilization, e.g. 5h 42% · 7d 63%, with warning/error coloring as you approach the limits.
• Hover it for a quick card: today / 7-day / month-to-date cost and tokens, your top model, and a 7-day sparkline — all before you even click.
• Click it to open the full dashboard:
  • Rate-limit gauges with reset countdowns
  • Tokens and estimated cost consumed today (input / output / cache read / cache write)
  • Daily stacked bar chart of the last 7 days, with cost
  • Per-model breakdown table with cost and request counts
  • 6-month token trend line chart

How it works

• Rate limits come from the same endpoint Claude Code's /usage command uses (api.anthropic.com/api/oauth/usage), authenticated with your existing Claude Code OAuth token (macOS Keychain, or ~/.claude/.credentials.json). These numbers are account-wide. No other data leaves your machine.
• Token counts are parsed from Claude Code's local transcripts (~/.claude/projects/**/*.jsonl) — fully offline, with caching so refreshes only re-read changed files. These cover this machine only; usage from other devices or claude.ai is not included.

Requirements

• Claude Code installed and signed in (claude → /login) with a Pro/Max subscription.
• VS Code 1.85+.

Development

npm install
npm run compile

Then press F5 in VS Code to launch an Extension Development Host.

Package with:

npx @vscode/vsce package

Settings

Caveats

• The usage endpoint is unofficial; if Anthropic changes it, limit display degrades gracefully (token stats keep working).
• Transcript retention follows Claude Code's cleanupPeriodDays (default 30 days), so 7-day history is normally complete.
