See what Claude Code is actually costing you — live, in your status bar.
Claude Code writes a detailed usage log for every session. This extension reads those local logs and turns them into a real-time spend meter and a usage breakdown. No API key, no account, no data leaves your machine.
Status bar:
$12.40 today · 38%— spend so far today and how full the context window is right now.
Free
- Live status bar — today's spend + current context-window burn (
38%of the model's window), refreshed every 30s. - Usage panel — total spend, breakdown by model, last 3 days.
Pro (license key)
- Budgets & alerts — set a daily USD budget; get warned at your threshold.
- Full history — 30-day spend trend.
- Per-project breakdown — see which repos burn the most.
- Export — pull the numbers out for your own reporting.
How it works
Reads ~/.claude*/projects/**/*.jsonl — the session logs Claude Code already
writes — and prices each message against current Anthropic rates (input, output,
and cache read/write tiers per model). Nothing is sent anywhere; all computation
is local.
Supports Opus, Sonnet, Haiku, and Fable model families, including prompt-cache read/write pricing (cache reads are billed at 0.1× input, writes at 1.25×).
Privacy
100% local. The extension never makes a network request to read your usage — it only parses files already on disk. License validation (Pro) is the only outbound call.
Requirements
- VS Code 1.85+
- Claude Code installed and used on this machine (so the logs exist)
