jsDelivr

jsDelivr is a content delivery network built specifically for open source projects. It pulls packages directly from npm and GitHub, caching them on a global network of servers spanning multiple cloud providers. You can request any file from any npm package or GitHub repository just by constructing a URL, and jsDelivr handles the rest. It supports automatic minification, bundling of multiple files into a single request, and fallback to alternative CDNs like unpkg and cdnjs if a package isn't hosted on its own infrastructure. There are API endpoints for listing package versions and files, and you can also serve ES modules via its npm ESM endpoint. The service is completely free to use, with no rate limits or registration required. It was created by the team behind the jsDelivr project and is used by millions of websites worldwide, including major WordPress plugins and popular JavaScript libraries. If you are shipping an open source library or just want to avoid managing your own static assets, jsDelivr is a reliable, performance-tuned option with a proven track record.
