AASA Validator

Apple App Site Association (AASA) Validator

Test that your domain serves a valid apple-app-site-association file for Universal Links. We run the same checks Apple uses and show you the parsed JSON.

Enter your website domain below. We'll fetch your apple-app-site-association file from /.well-known/apple-app-site-association and run the same checks Apple uses for Universal Links. If Universal Links still don't work, also verify your Xcode project's Associated Domains and entitlements.

This tool is not affiliated with Apple. It helps you verify that your AASA file is reachable and valid for Universal Links. For issues with your app configuration, see Apple's documentation on Associated Domains.
