Firebase Dynamic Links Migration Guide

Why Migrate from Firebase Dynamic Links?

Google deprecated Firebase Dynamic Links in August 2025. If you're still relying on FDL for deep linking, your links will eventually stop working. WarpLink is purpose-built as a replacement — fast edge redirects, deferred deep links, and install attribution out of the box.

Unlike other alternatives, WarpLink resolves every link at the Cloudflare edge in under 10ms. There's no cold start, no shared infrastructure bottleneck, and no surprise pricing. The free tier covers 10,000 clicks per month.

Migration Steps

The migration process takes about 30 minutes for most apps:

1. Create a WarpLink account at warplink.app and set up your organization.
2. Register your app with your iOS bundle ID and/or Android package name.
3. Install the SDK — Swift via SPM, Kotlin via Maven Central, or TypeScript via npm for React Native.
4. Replace link creation — swap DynamicLinks.dynamicLinks().createDynamicLink() with WarpLink's API.
5. Update link handling — replace DynamicLinks.dynamicLinks().handleUniversalLink() with WarpLink's SDK.

// Before (Firebase)
DynamicLinks.dynamicLinks().handleUniversalLink(url) { link, error in
  guard let link = link else { return }
  handleDeepLink(link.url)
}

// After (WarpLink)
WarpLink.shared.handleDeepLink { result in
  switch result {
  case .success(let deepLink):
    navigate(to: deepLink.path)
  case .failure(let error):
    print("Deep link error: \(error)")
  }
}

Feature Comparison

WarpLink covers every Firebase Dynamic Links feature and adds several improvements:

• Edge redirects — Sub-10ms globally vs Firebase's variable latency
• Deferred deep links — Preserve context through app installs
• Install attribution — Deterministic IDFV matching with fingerprint fallback
• Social previews — Automatic OG and Twitter Card tags for rich link previews
• Custom domains — Bring your own domain for branded short links
• Analytics — Real-time click analytics with deduplication
