Domain Age Checker

Domain Age Checker gives you quick context about the website you are visiting. Its compact toolbar badge shows the domain's age, while the popup provides registration and expiry dates, registrar, DNSSEC, nameservers, domain status, and the last update date when published by the registry. Key features: - Automatic domain-age toolbar badge - Accurate parent-domain discovery for subdomains - Public RDAP registration details - Expiry countdown and domain lifetime timeline - Copyable report and direct RDAP source link - Configurable badge format, age colors, and local cache - Dark mode support - No analytics, ads, accounts, or page-content access Domain registration data varies by registry. Domain age is informational and does not indicate whether a website is safe or trustworthy.
