Universal link builder

Enter a team ID, bundle IDs, domains and ordered path rules to generate an apple-app-site-association file and associated-domains entitlement, with a tester showing which rule claims each test URL.

This tool is in beta

Still being tested. If a result looks wrong, tell us.

The generated matching is Apple's own semantics: rules read top to bottom, first match wins, an excluded match or no match keeps the link in Safari, "*" spans any run of characters and "?" exactly one (so "?*" means at least one), and query rules check the named parameter only, in raw percent-encoded text. This tool writes the two files; it cannot fetch your domain or ask Apple's CDN whether it has picked the file up yet.

App, domains, and rules

10 characters, digits and capital letters
One per line, up to 20
Optional; adds the appclips section
One per line, up to 16. *.example.com covers subdomains but not the bare domain.
One per line, up to 64: include /products/*, exclude /account/*, plus ?q=?* and #fragment tokens. First match wins. // starts a comment.
Password AutoFill for these domains
Also emit appID plus a paths array for iOS 12 and earlier
Adds ?mode=developer entitlement lines; development devices then skip Apple's CDN
Presets

Everything computes as you type, including the URL tests below (up to 50). Nothing leaves this tab, and no file is fetched from any domain.
