Billing-grade accuracy
billing-gradeWTClaude reads the statusline data path — the same source behind your bill. Not broken logs, not estimates. Your real numbers.
Built on the right data from day one.
Most Claude Code trackers estimate your cost from session logs — which can drift from your
bill. WTClaude reads the statusline instead: the same source behind your bill. So in your
terminal the number you see is billing-grade — run
wtclaude compare
and see your own gap.

Your usage data is broken.
Most Claude Code trackers read JSONL session logs. Those logs record input tokens as 0 or
1 in about three-quarters of entries — they’re written mid-stream, before the response
finalizes, and never corrected. The result: the cost your tracker shows can drift from
what you actually spent — sometimes a little, sometimes a lot. A gap wide enough to choose
the wrong plan, miss a budget, or burn through agent credits without knowing. Run
wtclaude compare
to see yours.

Two budgets, one tracker
June 15 splits your billing into an Interactive pool and an Agent SDK Credit pool. WTClaude is built for both and lights up automatically on the day — no reinstall.

Session timelines, daily debriefs, model breakdowns, and a “what-if” plan calculator.

Just shipped: WTClaude tracks Claude Fable 5
— billing-grade cost in your terminal, and
wtclaude fable
forecasts the June-23 cliff (a labeled estimate; separate from the June-15 Agent-SDK change).
See it all on the web.
billing-gradeEverything the CLI tracks, in a dashboard you can actually look at. Your real Claude Code cost over time, a session timeline that shows where the expensive turns were, the compare view, the “what-if” plan calculator, your overall plan limit gauge with reset countdowns, and — as June 15 approaches — your Agent-pool forecast tile estimate .
Cost figures are billing-grade for Claude Code run in your terminal. The forecast tile is a clearly-labeled estimate.

Work on a laptop and a desktop? Turn on opt-in cloud sync and WTClaude totals your real usage across all of them — the number no single-machine tracker can give you. (Local-first by default; nothing leaves your machine until you switch sync on, and you see a preview of exactly what syncs before it does.)

Daily Agent-pool forecast
estimateA projected daily and monthly agent-pool spend versus your included credits, with a countdown to June 15. Install early — every day you track sharpens the projection.
The cost math is billing-grade; the pool split is a heuristic, so this is a forecast — never your exact future bill.
