Link Rel Auditor
Audit link rel tags for canonical, preload, preconnect, stylesheet, and alternate hints.
What the Link Rel Auditor does
Audit link rel tags for canonical, preload, preconnect, stylesheet, and alternate hints. A preload without an as value is flagged because the browser needs resource type context Adjust the controls and the preview updates immediately, so you can dial in exactly what you want and copy the result straight into your project — no build step and no account.
One thing to keep in mind: The tool checks markup shape, not whether the target URL is reachable.
Private and in your browser
Everything runs locally in your browser. Your input is never uploaded, so the tool stays fast and works offline, and the copy and download buttons always use the current result shown in the output panel.
