Due to some well-known reasons, many open-source libraries and ready-to-use Blog templates use foreign CDNs, which may result in unsatisfactory access speeds in mainland China. This can lead to very slow loading times for your website. I have compiled a list of currently stable free CDN sites that can provide good speeds for your site's resources both domestically and internationally.
Some links in the text do not have a visual interface, please take note.
Major Companies' Operations:#
ByteDance Static Resource Public Library (Very Stable)#
No updates, but existing resources are very fast.
Ele.me (Not Publicly Released)#
-
For example: https://npm.elemecdn.com/jquery@3.2.1/dist/jquery.min.js

Refer to UNPKG for usage of these two.

360 Frontend Static Resource Library#
Currently, the homepage returns a 404, but resources are available. The Font Acceleration Page is normal.

Usage needs to be explored on your own. Resources are not very complete, but they are fast.

Bootstrap#
Has had multiple negative reports, such as website downtime and poisoning, use with caution.
You may find that the major domestic companies are either not user-friendly, have limited resources, or do not update. If an unpublished CDN changes its URL one day, we have no recourse. Therefore, it is more advisable to use the following CDN sites, but please adhere to their respective TOS.
Other Useful Options#
7ED#

Xiaobai Cloud#
Zstatic CDN#
Sponsored by Upyun.
Zeyao Network#

Can revert to jsDelivr, UNPKG, cdnjs, usage is consistent with the reverted projects.
However, sometimes it is sponsored by domestic service providers, and if sponsorship ends, it defaults to Cloudflare, with speeds being inconsistent.
