CDNPulse is an independent, free public CDN that delivers open-source files from the npm registry and tagged repository releases. Developers can request a specific package version or release tag through a permanent, versioned URL; exact-version files are immutable, making them suitable for reliable production use. The service supports common web assets, including stylesheets and JavaScript modules, and offers browser-resolved module imports, combined file responses, directory listings, and minified variants where available.

Published source maps are served alongside package files, and immutable paths include integrity digests for verification. CDNPulse also resolves version ranges and release tags, with those resolutions cached for 12 hours. Its delivery network reports 96 edge locations, 41.

6 billion requests and 1. 78 petabytes of egress over 30 days, with 99. 987% rolling uptime.

Integration requires no account, API key, console, or origin configuration: developers use the requested URL directly. CDNPulse describes itself as a community-funded service, with bandwidth donated by listed operators and running costs published quarterly. It is not affiliated with package registries, repository hosts, or package authors
