Lookalike domain checker
Lookalike (typosquatting) domains exploit small visual or typing differences. This tool systematically generates the variants attackers most often register and shows which currently exist, so you can decide which deserve attention.
What this checks
- Up to ~120 high-likelihood variants per scan
- Which variants resolve in DNS
- Hosting and certificate indicators for those that respond
How to use it
- Enter your domain.
- Sort candidates by risk.
- Open evidence for the high-risk ones; allow-list domains you own.
Methodology and limitations
Only a sample of the possible variants is generated and Unicode (IDN) homoglyph coverage is limited. Automated indicators only, not legal findings. Read the full security methodology.

Frequently asked questions
Should I register all the lookalikes myself?
Registering the few most likely typos can be sensible, but it is impossible to cover everything. Monitoring is more practical than defensive registration alone.
