Free RSS and Atom Feed Linter

The linter will check a feed to ensure it is valid according to the RSS/Atom/JSONFeed specifications. In addition, it checks whether the feed contains optional features that provide maximum compatibility with various readers and provide an optimal user experience.

Currently, the linter supports linting RSS files. Atom, JSONFeed support coming soon!

Enter a URL to an RSS feed and the tool will fetch and lint. Want to lint a local file? The linter is powered by go-syndication, an open-source library for reading and writing syndicated formats. Click the link above to get instructions for running and linting your own local feeds.
