jsDelivr is a public, open-source CDN (Content Delivery Network) developed by ProspectOne, focused on performance, reliability, and security. It is free to use for everyone, with no bandwidth limits. It provides mirrors for npm, GitHub, WordPress plugins, and custom endpoints for several other projects with special requirements. If our regular endpoints don't work for your use case, let us know and we'll figure something out!
100% free for all open source projects. Non-open source not allowed.
Because it's expensive for each open source project to have to worry about CDN configuration and pay for bandwidth.
