Hey Product Hunt! I built Canonical Tag Checker because canonical mistakes are easy to miss and can confuse indexing signals. Paste a page URL and HTML, then review missing, duplicate, malformed, or mismatched canonical tags locally in your browser. It is free and requires no sign-up. I would love feedback on additional canonical edge cases to cover.
