Age Gate is a mature, actively developed WordPress plugin for adding age verification gates to entire websites or specific content types. The plugin is freely available on WordPress.org and supported by an official site at agegate.io. It offers three distinct verification methods - date-of-birth entry, simple yes/no confirmation, and redirect-to-external-site - allowing operators to match the gate type to their jurisdiction's requirements or audience expectations. Shortcodes enable granular per-post or per-page restrictions alongside site-wide configuration.

From version 1.4.0 onward, the plugin includes cache bypass support, which resolves the classic conflict between page-caching plugins and age gate functionality - a problem that caused incorrect behavior on high-traffic cached sites. Cookie-based verification memory avoids re-prompting returning visitors, and the plugin is architected to allow search crawler access, preserving SEO indexability of gated content. Customization of colors, fonts, layout, and verification messaging is built in.

For any adult WordPress operator subject to age-gating regulatory requirements - which includes operators in EU member states, the UK post-Online Safety Act, and other jurisdictions implementing age assurance mandates - Age Gate is the most widely validated solution in the WordPress ecosystem. Its WordPress.org listing means it receives scrutiny from the broader community and is tested against major WordPress and PHP version updates. A foundational compliance plugin that belongs in every adult WordPress site's stack.
