Validate RSS and Atom feeds before subscribers see the breakage.
An RSS feed validator checks whether an RSS or Atom document is valid XML and includes the fields feed readers need to parse it reliably. This free AICurate checker flags structural errors, bad dates, encoding problems, and incomplete items so you can fix a feed before it breaks in readers, apps, or automations.
Use the tool to catch malformed XML, missing required elements, timestamp formatting issues, encoding mismatches, and incomplete media metadata before the feed reaches readers, newsletter systems, or automations.

Each validation run produces grouped results for structure, required elements, timestamps, encoding, and item or entry completeness. Failed checks include concrete repair guidance so you can update the feed and test again quickly.
FAQ
Common questions about RSS validation
What does this RSS feed validator check?
It checks XML syntax, RSS 2.0 and Atom required elements, date formats, encoding declarations, and item or entry completeness. It also reviews optional image and enclosure tags for common compatibility issues.
Does the tool validate Atom feeds too?
Yes. The validator detects Atom feeds, checks core Atom elements such as feed title, id, updated, and entries, and verifies RFC 3339 timestamps along with basic media link quality.
Why can a feed look valid but still fail in readers?
Many readers are stricter than browsers. A feed can render as XML but still break because it has missing required tags, malformed dates, bad URLs, encoding mismatches, or incomplete media metadata.
Should I validate my feed after every change?
Yes. Validate after template updates, CMS migrations, plugin changes, or feed URL changes. Small formatting mistakes can prevent new items from appearing in readers, newsletter tools, or aggregators.
