Pricing FAQ

Is there a free tier?
Yes. The Free tier includes everything the tool does today — single hostname checks with full chain analysis. No account or payment needed.
When will Pro features be available?
Pro features — batch checks (up to 10 hostnames), JSON/CSV export, and rate-limited API access — are planned but not yet built. Subscribe to be notified when they launch. No payment is taken during this pre-launch period.
Do you offer email alerts or scheduled checks?
No. Chainlook is a diagnostic tool you use when you need an answer. There is no email sender, no alerting system, and no scheduled re-checking in this product. All checks are on-demand.
Is my data stored or saved?
No. Every check is stateless — no accounts, no databases, no history. The result is displayed in your browser and discarded when you navigate away.
