Feed diagnostics for podcasters and publishers. Type a URL. See what is actually wrong.

A feed reader or podcast directory rejected your feed and told you almost nothing useful. Rsscheck fetches the feed, parses it the way a real reader does, and reports what it found — the format, item count, date range, and the specific defects that break readers.


What Rsscheck finds

  • Format detection — RSS 2.0 or Atom, with channel/feed-level metadata
  • Item-level diagnosis — missing titles, missing or duplicate GUIDs, unparseable dates, missing links
  • Encoding and content-type checks — detects mismatches between declared and actual encoding, wrong Content-Type headers
  • Date range analysis — newest and oldest publication dates across all items
  • Plain explanations — each finding says what breaks as a result, because “invalid” never helped anybody fix a feed

How it works

  1. 1 Paste your feed URL into the input field.
  2. 2 Rsscheck fetches the feed and parses it as a real reader would — it fetches only the URL you provide, no crawling or media downloads.
  3. 3 Read the structured report: format, item count, date range, and every defect that would break a reader, each with a plain explanation of the impact.
Answers when you ask it. Rsscheck does not crawl feeds, download enclosures, or check on a schedule. Submit a URL, get a diagnosis — that is the whole interaction.
