🎯 iOS-Compatible Navigation Tester

Enter your App Clip URL or Universal Link below. Click any solution button to test.

🔗 Enter Your URL Manually:

👆 Solution 1: Manual Click Anchor Tag MANUAL

How it works: Uses pre-existing hidden <a> tag. Updates its href attribute at runtime based on textbox input. User clicks trigger navigation - iOS Safari intercepts to show App Clip card.

• Requires user interaction (manual click) • No dynamic element creation • Simple HTML approach

🔗 Solution 2: Programmatic Link Generation & Click Event RECOMMENDED

How it works: Dynamically creates <a> tag in JavaScript, sets href, appends to DOM, then dispatches MouseEvent('click') to trigger navigation. iOS Safari intercepts the programmatic click event for App Clip handling.

✓ Automatic - no manual effort • ✓ Fully programmatic • ✓ Better than window.location redirect

📡 Hit Endpoint / Prefetch Metadata (no redirect)

All options run on page load. Uses the URL from the text field above (or default). Click a card to trigger again.

1. fetch (no-cors)

fetch(url, { mode: 'no-cors' }) — fire-and-forget; no redirect.

2. Image beacon

new Image().src = url — GET request; no redirect.

3. sendBeacon

navigator.sendBeacon(url) — background request; no redirect.

4. Hidden iframe

Load URL in a hidden <iframe>; main page stays.

5. link rel=prefetch

Add <link rel="prefetch" href="..."> to document.head; browser prefetches into cache.

6. object / embed

Create <object data="url"> (or <embed src="url">); loads URL without navigating.

7. Link header (server)

Server sends Link: <url>; rel=prefetch when serving this page. Set in public/_headers (or netlify.toml if deploying from repo root); no client action.

⚠️ Why These Solutions Work:

Solution 1 & 2: iOS Safari intercepts HTTPS link clicks (manual & programmatic) to show App Clip cards. If app is installed, iOS automatically opens the app instead.
iOS CANNOT intercept JavaScript redirects like window.location or window.location.replace()
Solution 2 is recommended for automatic, programmatic App Clip invocation with HTTPS URLs
Both solutions use anchor tag clicks which iOS Safari recognizes and intercepts for App Clip handling
