Questions

Are these URLs actually checked?

Yes, and that is the whole point of this site. Every url here was requested and the answer recorded — 276 of 290 responded successfully at the last check on 2026-09-05. A url we could not verify is labelled unverified rather than presented as working, and a url that failed says so along with how long it has been failing.

What is an SRI hash and do I need one?

Subresource integrity pins the exact bytes a browser will accept. If the file at that url ever changes, the browser refuses to run it instead of running something you did not review. Use one for anything on a page that handles user data. Only cdnjs publishes hashes, and only for the exact file they computed it from — attaching a hash to a different url blocks the script and looks exactly like the CDN being down.
