Podcast Feed Checker

Paste a feed URL, get a straight answer on what Apple Podcasts and other directories will complain about.

Feed URLs are fetched through this site because browsers block direct cross-site requests. We do not log or store them, and the results below are built entirely in your browser.

What it checks

  • RSS 2.0 structure and valid XML
  • Required tags: title, description, language, author, explicit
  • Category against the official Apple Podcasts list
  • Artwork: square, 1400 to 3000 pixels, actually measured
  • Episode enclosures, audio types, and durations
  • GUID uniqueness and valid pubDates

Why this exists

The old standbys, Cast Feed Validator and Google's podcast validator, are gone, and most replacements want an account or bury results in upsells. This one is free, instant, and runs the analysis in your browser. Built by Cartegy, a studio that also runs its own podcast feeds.

Frequently asked questions

What size does Apple Podcasts artwork need to be? +

Square, between 1400x1400 and 3000x3000 pixels, as a JPG or PNG. This checker downloads your artwork and measures the real dimensions.

Does this work for Spotify and other directories? +

Yes in practice. Spotify, Amazon Music, and most directories read the same RSS 2.0 feed. Apple's requirements are the strictest, so a feed that passes here is in good shape everywhere.

Do you store my feed URL? +

No. The public URL is fetched once so your browser can analyze the feed, and it is not logged or stored. The report is built entirely on your device.

Why do episodes duplicate or re-download in podcast apps? +

Usually missing or duplicated GUIDs. Each episode needs a stable, unique guid tag; this checker flags both problems.
