FAQ
What does this tool tell you?
The Deep Link URI Validator checks URI scheme, Universal Link, and Android App Link format with fallback behavior analysis for iOS and Android.
What affects the result most?
URI scheme: myapp://host/path — custom scheme, no HTTPS verification required. Universal Links (iOS): HTTPS with apple-app-site-association file — verified, no browser prompt. App Links (Android): HTTPS with assetlinks.json at /.well-known/ — verified, opens directly.
How should I use the result?
Treat the tool's output as a first-pass check, not a proof of correctness. A clean pass means no issues in the patterns this tool recognizes; a failure points to a specific problem you can investigate in your source. The underlying spec is the authoritative source for edge cases.
