Following up on the release of our AMP Validator Chrome Extension, today we’re releasing another way to validate your AMP pages: validator.ampproject.org provides a simple web UI for the AMP Validator.
You can provide a URL to load the AMP HTML source code from, or copy/paste your source code, and the editor displays validation messages between the lines. Edits trigger revalidation, providing interactive feedback.
It’s open source, so please feel free to file bugs, send fixes, or tweak it for your own needs. Please enjoy!
