Built on the right data from day one.

WTClaude shows you what Claude is really costing you — built on the right data, and honest about the rest. It starts with Claude Code in your terminal, where we read the billing-grade numbers Anthropic bills you from.

Now with a web dashboard and opt-in multi-device sync — your real Claude Code numbers, everywhere you work.

Billing-grade for Code in your terminal; an honest estimate for Code in the desktop app. Honest, clearly-labeled estimates for everything else — we never show an estimate as if it were exact.

Three models now. One honest way to choose.

Opus 5.5 is the Claude Code default. Fable 5.1 is the default Fable model, and how Fable bills depends on your plan. Sonnet 5 has the lowest input and output rates of the three. WTClaude prices all three from your own real usage — so you choose on what it actually costs you, not the rate card.

Opus 5.5, priced right

The default in Claude Code since v2.1.280 (September 22, 2026), on every paid plan. We price it at $4/$20, with cache reads at $0.20 per million, off the model’s own reported tokens, so nothing goes untracked — and we show you the real number, not the sticker.

Fable, priced by your plan

Permanent since July 20, 2026, and billed by plan, not by date: on Max, Team Premium and Enterprise Premium it’s included up to 50% of your weekly usage limit; on Pro and Team Standard it’s usage credits at $10/$50 from the first token. Fable 5.1 and Fable 5 share those rates and differ on cached input — $0.25 against $1 per million tokens. WTClaude reads the billing-grade cost of each in your terminal and forecasts what your pace would cost in credits — a labeled estimate at standard API list rates; bundle discounts up to 30% and promos not reflected.

Compare all three

wtclaude compare-models re-prices your recorded usage across Opus 5.5, Sonnet 5, and Fable 5.1 — what would this month cost on each? Split by surface (Code billing-grade, Cowork a labeled estimate, Chat excluded). In the CLI and the dashboard.

Comparisons re-price your recorded usage, not the same task run on each model — every projection is a labeled estimate. We surface the cost of the choice; we don’t judge which model is “better.”
