Lookalike Domain Checker

How the score works

Each look-alike gets a final score from 1 to 100, combining two signals:

  • Visual deception (1–99) — how easily the human eye misreads the variant for the original. Substitutions like l→1 or i→l rate highest.
  • Threat signal (0–30) — DNS evidence the variant is registered, parked, serving a website (A record), or accepting mail (MX record). A registered domain pointing at live mail infrastructure is the highest-priority threat.
  • Final score = min(100, visual + threat). A look-alike that's both visually deceptive and live tops the list.

We check four mutation categories: substitution (digit/letter swap), typo (transposition, omission, doubling), TLD swap, and hyphenation.
