RSS / Atom / JSON Feed Inspector

Fetch any RSS 2.0, Atom 1.0, or JSON Feed by URL (via CORS proxy) or paste raw XML/JSON; inspect channel metadata, browse items, and validate required and recommended fields.

External feeds are fetched by our server (public sites on the standard web ports only, up to 2 MB) because browsers can't read most cross-origin feeds. No feed data is stored.

Frequently asked questions

Is my data uploaded to a server?

Partially — see the note above. Feed URLs are fetched via a CORS proxy (corsproxy.io, with allorigins.win as fallback) since browsers can't fetch cross-origin feeds directly. No feed data is stored.

How do I check if my RSS feed is valid?

Enter the feed URL or paste the raw XML into the RSS / Atom / JSON Feed Inspector. It reports channel metadata, lists items and has a Validation tab that flags missing required and recommended fields.

Which feed formats can I inspect?

RSS 2.0, Atom 1.0 and JSON Feed 1.0/1.1. You can load a feed from a URL or paste or drop the XML or JSON directly.

Can I validate a feed that is not public yet?

Yes. Use the Paste XML or JSON Feed input instead of a URL, so nothing has to be reachable from the internet.

Can I generate an RSS feed here?

Yes, the Generate tab builds an RSS 2.0 XML feed from channel details and items you add. You can load the result into the inspector to validate it.
