About duolingo.com

We reviewed duolingo.com and found a strong trust profile with some mixed public feedback. Current checks lean more legitimate than deceptive, and the current trust score is 95/100. Key signals include strong community presence across verified profiles: X, LinkedIn, YouTube, business infrastructure, and popular site. We also saw reputation caution signals from third-party review sources, so commercial claims should still be checked independently. Verify key details and recent independent feedback before relying on this site for important actions.

FAQ

Is duolingo.com safe?

Based on current analysis, duolingo.com leans generally safe with a 95/100 trust score. Key trust factors include 16.8-year domain history, public traffic rank, and business infrastructure; mixed review signals should still be checked.

Why does duolingo.com look trustworthy?

Key factors include registrar information (Amazon Registrar, Inc.), hosting in US, a domain age of 16.8 years, and presence in public traffic rankings. Major malware and phishing engines did not report active blacklist detections at the time of review, but reputation-related warning signals were still present. The trust score blends security detections, domain and infrastructure signals, on-page behavior patterns, and public review history when available. The overall assessment remains mixed because third-party reputation sources do not point to a fully consistent trust profile.
