Find out why your feed isn't working
Feed broken, rejected, or not updating? Check a live URL or file for free. We show what needs attention and whether an optional repair can be tried. You can check OPML imports too.
URL, paste, and upload workflows RSS, Atom, podcast feeds, and OPML Optional repair when supported
Does this sound familiar?
These are feed and OPML problems CorrectFeed can check. If one matches your case, start with a free check.
XML
Your feed has invalid XML
A reader or validator reports malformed XML, bad escaping, invalid characters, or broken namespaces.
URL
The feed URL returns 404 or cannot be fetched
The feed exists somewhere, but readers, crawlers, or podcast apps cannot reach the current URL.
Redirects
Redirects are confusing feed readers
A redirect chain, loop, mixed protocol, or stale feed URL prevents reliable discovery and updates.
Podcast
Podcast enclosures or metadata are malformed
Episode audio, media types, GUIDs, dates, or channel metadata fail strict podcast validation.
OPML
An OPML import fails or misses subscriptions
A reader imports only some feeds, rejects the OPML file, or loses folder structure during migration.
Updates
The feed validates but stops updating
Dates, GUIDs, duplicate items, cache headers, or Atom entry IDs cause readers to miss new posts.
How it works
02
See what needs attention
Find out what may be stopping updates, delivery, or an OPML import, and whether this input has a supported repair.
03
Choose a repair if available
A paid repair is optional. If you choose one, a download is offered only after verification confirms improvement. Some problems need a change at the source.
Problems we check and may repair
Repair depends on the exact issue. Live feed URL, hosting, and redirect problems may need a change at the publisher.
- Malformed XML, escaping, and encoding
- Repair common parser-breaking issues such as invalid characters, bad entities, byte-order marks, and encoding mismatches.
- Feed metadata, dates, GUIDs, and duplicate items
- Normalize fields that often make readers skip entries, show stale content, or treat new posts as duplicates.
- Podcast enclosures and media metadata
- Identify malformed enclosure URLs, missing media types, and podcast-specific fields that app directories expect.
- Namespaces and RSS/Atom structure
- Catch misplaced elements, missing required fields, and namespace issues that strict validators reject.
- OPML outlines and feed migration files
- Validate subscription lists, preserve outline structure, and flag entries that cause feed reader import failures.
Privacy
Processed in memory
Uploaded feed and OPML files are processed for validation and repair without storing the original upload as a product feature.
Minimal logging
Logs focus on request IDs, operational status, and abuse prevention rather than feed payloads.
Encrypted in transit
Uploads, URL checks, API calls, and downloads use HTTPS.
Building something with feeds?
CorrectFeed also has an API for teams that need feed validation, autofix, and OPML checks in production workflows.
Simple REST API
POST feed XML or OPML and get validation results, changes, and repaired output where available.
curl -X POST "https://api.correctfeed.com/api/autofix-feed" \
-H "Authorization: Bearer $CORRECTFEED_KEY" \
