Universal Link Path Matcher

Paste your apple-app-site-association file and a list of URLs, and see exactly which ones iOS would open in your app versus hand back to Safari — honoring * and ? wildcards, query and fragment patterns, and exclusion rules. Runs entirely in your browser.

Why universal links open the website instead of your app

When a universal link opens Safari instead of your app, the cause is almost always the path patterns in your apple-app-site-association file — an exclude rule that fires too early, a wildcard that's too narrow, or a query parameter the pattern doesn't account for. This matcher lets you check a batch of real URLs against your AASA components (and legacy paths) before you ship.
