jsDelivr: common questions

Is jsDelivr free to use?

Yes — jsDelivr is a free developer tools API. Free tier: Free, no key. Whether the free tier allows commercial use is unclear — check the provider docs.

Does jsDelivr need an API key?

No — jsDelivr needs no API key or signup. You can call it straight away; rate limits still apply (Unpublished).

Can I call jsDelivr from the browser?

Yes — jsDelivr returns CORS headers over HTTPS, so front-end code can fetch it directly with no backend proxy. Use the fetch snippet on this page, or hit "Run live" to try it now.

Is jsDelivr up right now?

As of our last scheduled check, jsDelivr is unmonitored. We re-probe it every sweep — the status badge and uptime chart above always show the latest.
