jsDelivr is a global public CDN for frontend developers and open-source projects, specializing in providing free, fast, and reliable distribution services for frontend static resources such as JavaScript, CSS, fonts, and images.
Unlike traditional commercial CDNs, jsDelivr's core positioning is not enterprise-level traffic billing or protection capabilities, but rather serving as “frontend ecosystem infrastructure” for the open-source community and developers.
In practical use, jsDelivr is frequently employed for accelerating third-party libraries, hosting open-source project resources, and distributing frontend dependencies, making it one of the most frequently used CDN tools in web development.

7. jsDelivr Frequently Asked Questions
Is jsDelivr suitable for use as a primary CDN for websites?
Not suitable. jsDelivr is better suited as a CDN for public frontend resources rather than for distributing entire websites or accelerating dynamic content.
Does jsDelivr support HTTPS?
Support: All resources are accessed via HTTPS by default.
How reliable is jsDelivr?
Through a multi-CDN architecture and global node redundancy, overall stability is relatively high, but no SLA commitment is provided.
Does jsDelivr have any access restrictions?
There are no explicit traffic restrictions, but it is primarily intended for the distribution of public, legal, and open-source resources.
Does jsDelivr support private files?
Not supported. jsDelivr only works with publicly accessible resources.
Editor's Note
jsDelivr functions more as a “public infrastructure” within the frontend ecosystem than a traditional commercial CDN. For frontend dependencies, open-source resources, or public static file distribution, jsDelivr is nearly the default choice. However, when handling business data, private content, or security requirements, it must be used alongside other commercial CDNs.
