How to use this tool
Add hints, set resource URLs or origins and generate. Review font/fetch CORS modes, then copy or download the HTML.
When not to use it
No resources are requested here. Hints are advisory and can waste bandwidth; verify priorities and credentials in your own browser network panel.
