Extract and check QR destinations locally before opening them.

See where a link really goes and review the redirect timeline.

Compare a suspicious domain against a trusted brand or website.

Review suspicious invoice, gift-card, payroll, and vendor-change requests locally.

Inspect sender, reply-to, authentication, and routing signals locally.

Check public SPF, DMARC, optional DKIM, and MX signals for a domain.

Plan QR campaign destinations before printing, sending, or publishing.

Review campaign context for email, SMS, QR, ads, and customer links.

Map brand exposure areas and create a practical review plan.

Generate a clean printable report from scanner results without storing it.

Self-check your website before launch, sign-in, campaigns, or payments.

Learn the practical signals behind CheckLink verdicts.

Useful checks before you click. Risk signals, not guarantees. Private by design where possible. No account required and no scan history stored.

Use the Trust Lab for first-pass context, then request manual review when a link affects money, credentials, customers, or business operations.
