QUICK GUIDE

How to use this tool

Enter CDN URLs or open the files. Your browser downloads each file directly, which works only when the server sends CORS headers (major CDNs do). Generate a new hash whenever a file changes: a file that no longer matches is blocked.

Files are downloaded directly from the URLs you enter and hashed in your browser.
