Teardown is metered in credits: 1 credit = $0.01. You always see a credit range before a run starts, and you approve it. Nothing auto-runs.
Credit cost by tier
| Tier | Typical target | Cost |
|---|---|---|
| Quick read | small/static site, single-lens | ~5–15 credits ($0.05–$0.15) |
| Standard teardown | mid-size SPA or SSR app, full lens | ~20–60 credits ($0.20–$0.60) |
| Deep dive | large multi-route app, everything-lens | ~60–150 credits ($0.60–$1.50) |
Focus lenses other than "Everything" multiply the base cost by 0.6 — a frontend-only read of a big site costs about 40% less than the full teardown.
Free bucket
Every new account starts with a free 100-credit bucket — enough for roughly two to five standard teardowns. No card required at sign-in; you sign in with an email magic link.
Billing rules
- A run is rejected up front if your balance is below the estimate's upper bound — you'll never get halfway charged.
- After completion you are charged
credits_spent, computed from what was actually analysed, which lands inside the estimated range. - Credits are a display unit over model + compute cost; the exact spend per stage is written to your run log.
