IOS DEEP LINK DIAGNOSTICS

Universal Links Checker

Diagnose the public server-side configuration behind iOS Universal Links without installing an app or providing a private URL.

What this checker can prove

This tool verifies the public AASA side of Universal Links: transport, response format, association identifiers, and routing rules. It does not inspect your app binary, entitlements, device cache, or runtime navigation code.

Use it when

A Universal Link suddenly opens Safari instead of the app.
A deployment changed paths or components in the AASA file.
You need to compare the public association state with the identifiers expected by your app.
You want a quick server-side check before investigating device-specific behavior.
