How it works

pageflare analyzes all links and external resources across every page — finding external links, third-party scripts, and font references.

Every external link that opens in a new tab gets noopener and noreferrer. Broken target attributes on internal links are fixed.

Preconnect and dns-prefetch hints are injected for all detected third-party domains — speeding up external resource connections.
