Best Firebase Dynamic Links Alternative in 2026

TL;DR: WarpLink is the best Firebase Dynamic Links alternative for developers and small teams. It covers everything Firebase offered (universal links, deferred deep links, install attribution, analytics) and adds sub-10ms edge redirects, open source SDKs with zero dependencies, and transparent pricing starting at $0/month. No sales calls, no contracts. Create a free account and have deep links working in five minutes.

What Happened to Firebase Dynamic Links?

If you're reading this, you probably already know: Google deprecated Firebase Dynamic Links in August 2025. The service that thousands of mobile developers relied on for deep linking, deferred deep links, and install attribution was officially sunset with no direct replacement.

Google's recommendation? Migrate to a third-party solution. That's it. No first-party successor, no migration tool, no recommended vendor. Just a deprecation notice and a FAQ page.

The Timeline

The deprecation followed a pattern familiar to anyone who has built on Google platforms:

August 2025: Firebase Dynamic Links officially deprecated. Existing links continue to work during a transition period.
August 2026: All Firebase Dynamic Links will stop resolving. Links will return errors instead of redirects.

If you haven't migrated yet, you have months, not years. Every Firebase Dynamic Link in your app, your emails, your marketing campaigns, and your social posts will break when the deadline hits.

Why Google Deprecated It

Google never gave a detailed explanation, but the reasons are straightforward. Firebase Dynamic Links was a free service with no revenue model. It required ongoing infrastructure investment. And Google was consolidating Firebase around its revenue-generating products: Authentication, Cloud Firestore, and Cloud Functions.

The deeper issue is that deep linking is hard to maintain well. Universal Links and App Links require constant updates as Apple and Google change their platform requirements. Bot detection needs regular tuning. Attribution accuracy demands sophisticated fingerprinting. These are not problems that get easier over time.

What It Means for Your Links

Every Firebase Dynamic Link your users have bookmarked, saved in messages, or indexed by search engines will stop working after the deprecation deadline. This includes:

Links shared on social media
Links embedded in emails and push notifications
Links in QR codes on physical materials
Links indexed by Google Search
Links hardcoded in older versions of your app

The links don't gradually degrade. They break completely. One day they redirect, the next day they return an error. This makes migration urgent, not optional.

What Developers Need from a Firebase Dynamic Links Alternative

Before comparing specific solutions, it helps to define what "good" looks like. Firebase Dynamic Links had real limitations, so a replacement should do more than just replicate it. Here's a framework for evaluating any Firebase Dynamic Links alternative.

Link Reliability and Speed

The most basic requirement: links should work. Every click should resolve to the correct destination with minimal latency. This sounds obvious, but it's where many solutions fall short.

Firebase Dynamic Links had variable latency depending on server location and load. A modern replacement should resolve redirects at the edge, as close to the user as possible. Target: under 10 milliseconds for any redirect, anywhere in the world.

Questions to ask:

Where do redirects resolve? Origin servers or edge network?
What's the p95 redirect latency?
What happens during traffic spikes?
Is there a cold start penalty?

Platform Coverage

A single URL should work across iOS, Android, and web. When a user taps a link:

iOS: Open the app via Universal Links, or fall back to the App Store
Android: Open the app via App Links, or fall back to the Play Store
Web: Open the destination URL in the browser if no app is installed

Firebase Dynamic Links handled this with a single link format. Any replacement needs the same capability. Bonus points if the solution handles the platform-specific configuration files (AASA for iOS, assetlinks.json for Android) automatically.

Deferred Deep Links

This is the feature that separates real deep linking from basic URL shortening. Deferred deep links preserve context through the app install flow:

User taps a link to a specific product in your app
User doesn't have the app installed, gets redirected to the App Store
User installs the app
App opens and navigates directly to that specific product

Without deferred deep links, the user installs the app and lands on the home screen. The context of why they tapped the link is lost. For referral programs, content sharing, and onboarding flows, this is a dealbreaker.

Attribution Accuracy

Attribution answers the question: "Where did this user come from?" After Apple's App Tracking Transparency (ATT) framework effectively killed IDFA-based tracking, attribution accuracy depends on alternative signals:

Referrer matching: Using the HTTP referrer when available
Device ID matching: IDFV (Identifier for Vendor) for deterministic re-engagement
Fingerprinting: Combining device signals (model, OS version, screen size, language) with IP address for probabilistic matching

A good solution uses a cascade of these strategies, falling back from most accurate to least accurate. It should also be transparent about which strategy matched each attribution, so you can gauge confidence.

SDK Quality

The SDK is what your app ships with. It runs on every user's device. SDK quality matters more than dashboard features because it directly affects your app's performance and your users' experience.

Evaluate SDKs on:

Size: Every kilobyte adds to download time and storage. Firebase's SDK was already large because it bundled the full Firebase framework.
Dependencies: Third-party dependencies are attack surface. They can introduce vulnerabilities, licensing conflicts, and unexpected behavior. Zero dependencies is the gold standard.
Open source: Can you read the code? Can you audit what data the SDK collects? Can you file issues and contribute fixes?
Platform support: Native SDKs for iOS (Swift) and Android (Kotlin) at minimum. React Native and Flutter support for cross-platform teams.

Pricing Transparency

This is where the Firebase alternatives diverge most sharply. Firebase Dynamic Links was free. Most alternatives are not, and many hide their pricing entirely.

There are three pricing models in the deep linking market:

"Contact sales": You fill out a form, get a demo, negotiate a contract. Typical minimums: $500-2,000/month with annual commitments. This is how enterprise platforms operate.
Usage-based with visible pricing: You can see the tiers, understand the costs, and sign up without talking to anyone. This is the model that works for developers and small teams.
Free/open source: You run everything yourself. Full control, but significant maintenance burden. No support for deferred deep links or attribution without building it from scratch.

If you're coming from Firebase (free), the jump to "contact sales" pricing is steep. Look for solutions with transparent, published pricing and a free tier that lets you evaluate without commitment.

Migration Effort

How hard is it to switch? Migration effort depends on:

Link format: Can you use custom domains to maintain your existing URL structure?
SDK integration: How many lines of code need to change?
API compatibility: Can you recreate your existing links programmatically?
Feature parity: Does the replacement cover everything you used in Firebase?

A 30-minute migration is realistic for most apps. A multi-week migration is a red flag.

WarpLink as a Firebase Dynamic Links Alternative

Let's walk through each evaluation criterion and show how WarpLink addresses it.

Sub-10ms Edge Redirects

Every WarpLink redirect resolves at the global edge network. There is no origin server in the redirect path. When a user taps a link, the nearest edge node reads the link configuration from a distributed key-value store and returns the redirect in under 10 milliseconds.

This matters because redirect latency is user-facing latency. A 200ms redirect is noticeable. A 500ms redirect feels broken. Firebase Dynamic Links resolved through origin servers with variable latency depending on geography and load. WarpLink eliminates that variable entirely.

There is no cold start penalty. The edge worker is always warm, always ready. Traffic spikes don't affect redirect performance because the edge network scales horizontally across hundreds of locations.

Full Platform Coverage with Automatic Configuration

WarpLink handles iOS Universal Links, Android App Links, and web fallbacks from a single URL. Register your app in the dashboard with your bundle ID (iOS) and/or package name (Android), and WarpLink automatically generates and serves the required configuration files:

Apple App Site Association (AASA): Served at /.well-known/apple-app-site-association on your link domain
assetlinks.json: Served at /.well-known/assetlinks.json on your link domain

These files are regenerated automatically whenever you update your app configuration. No manual JSON editing, no server configuration, no forgetting to update after a team ID change.

Fallback behavior follows a clear priority chain: per-link fallback URL, then app-level fallback (store URLs), then organization default. You set it once and it works for every link.

Deferred Deep Links That Work

WarpLink's deferred deep linking preserves context through the entire install flow. Here's the technical implementation:

User taps a WarpLink URL
The edge worker captures device signals and stores them with the link context
User gets redirected to the app store
User installs and opens the app
The WarpLink SDK calls the attribution endpoint with the device's signals
The server matches the signals against stored click data and returns the original deep link context
Your app navigates to the intended screen

The matching uses a multi-strategy cascade for accuracy:

Referrer matching: Most accurate when available
Device ID (IDFV): Deterministic matching for re-engagement
Fingerprint matching: Combines device model, OS version, screen dimensions, language, and IP address

This cascade runs in order from most to least accurate. Each attribution includes which strategy matched, so you always know the confidence level.

// iOS: handle deferred deep links after install
WarpLink.checkDeferredDeepLink { result in
  switch result {
  case .success(let deepLink):
    // Navigate to the content the user originally tapped
    navigate(to: deepLink.path, params: deepLink.queryParameters)
  case .failure:
    // No deferred deep link found (first organic install)
    break
  }
}

Open Source SDKs with Zero Dependencies

All WarpLink SDKs are MIT-licensed and open source. You can read every line of code, audit the data collection, and contribute improvements.

More importantly, every SDK has zero third-party dependencies:

iOS SDK: Swift, distributed via Swift Package Manager
Android SDK: Kotlin, distributed via Maven Central
React Native SDK: TypeScript bridge to native SDKs, distributed via npm

The total SDK size is under 200KB. Compare this to Firebase's SDK, which required the full Firebase framework and added megabytes to your app bundle.

Zero dependencies means zero supply chain risk. No transitive vulnerabilities, no license conflicts, no unexpected breaking changes from upstream packages. Your deep linking integration depends on exactly one thing: the WarpLink SDK.

// React Native: full integration in under 20 lines
import { WarpLink } from '@warplink/react-native';

// Initialize once at app startup
WarpLink.configure({ apiKey: 'wl_live_xxx' });

// Handle deep links (cold start and warm start)
WarpLink.onDeepLink((link) => {
  navigation.navigate(link.path, link.queryParameters);
});

// Check for deferred deep link after install
const deferred = await WarpLink.checkDeferredDeepLink();
if (deferred) {
  navigation.navigate(deferred.path, deferred.queryParameters);
}

Full REST API and MCP Server

Every feature available in the WarpLink dashboard is also available through the REST API. Create links, manage apps, query analytics, and configure domains programmatically.

# Create a deep link via API
curl -X POST https://api.warplink.app/v1/links \
  -H "Authorization: Bearer wl_live_xxx" \
  -H "Content-Type: application/json" \
  -d '{
    "destinationUrl": "https://myapp.com/products/123",
    "iosDeepLink": "myapp://products/123",
    "androidDeepLink": "myapp://products/123",
    "title": "Product 123",
    "ogTitle": "Check out this product",
    "ogDescription": "The best product you have ever seen"
  }'

WarpLink also includes an MCP (Model Context Protocol) server, free on all plans. This means AI agents and coding assistants can create and manage deep links directly through your existing AI workflows. The MCP server uses the same API keys and rate limits as the REST API.

When someone shares a WarpLink URL on social media, bots (Twitter/X, Facebook, Slack, iMessage, etc.) need to fetch Open Graph and Twitter Card metadata to render a rich preview. Real users need a fast redirect to the destination.

WarpLink handles this automatically. The edge worker detects bot user agents and serves full HTML with OG and Twitter Card tags. Real users get an instant 302 redirect. You configure the preview metadata (title, description, image) when creating the link, and it works everywhere.

Firebase Dynamic Links had limited social preview support. Enterprise platforms handle it but charge for the privilege. With WarpLink, rich social previews work on every plan, including free.

Links That Never Break

Here's a design decision that matters: WarpLink redirects always work, even if you exceed your plan's click limit.

When you hit your click limit on the free tier, your analytics dashboard is gated behind an upgrade prompt. But every link continues to redirect correctly. Your users never see an error page or an interstitial ad. Your links in emails, social posts, and QR codes keep working.

You'll get email warnings at 50%, 80%, and 90% of your click limit, giving you time to upgrade if needed. But the links themselves are never blocked.

Pricing Comparison

Pricing is where the Firebase Dynamic Links alternatives differ most dramatically. Firebase was free. Enterprise platforms start at hundreds of dollars per month. WarpLink sits in between, with a generous free tier and transparent paid tiers.

Plan	Price	Clicks/month	Links	Apps	Team members	Custom domains	Data retention
Free	$0/mo	10,000	100	1	1	0	90 days
Starter	$19/mo	100,000	1,000	5	3	3	180 days
Growth	$49/mo	500,000	10,000	20	10	5	1 year
Scale	$99/mo	2,000,000	Unlimited	Unlimited	Unlimited	10	3 years

Every plan includes:

Unlimited redirects (clicks count toward analytics, not redirect blocking)
Full API access
MCP server access
Social previews
Deferred deep links
Install attribution

No per-link fees. No feature gating. No "contact sales" for pricing information.

How This Compares

Pricing model	Firebase Dynamic Links	WarpLink	Enterprise Platforms
Starting price	Free	Free	$500-2,000+/mo
Pricing visible	Yes	Yes	No ("contact sales")
Free tier	Unlimited	10K clicks/mo	None
Annual contract	No	No	Usually required
Credit card for trial	No	No	Often required
Price per 100K clicks	$0	$0-19	$50-200+ (estimated)

If you're a solo developer or small team, WarpLink's free tier covers most early-stage apps. The jump from free to $19/month is manageable when your app grows beyond 10,000 clicks per month. And $99/month for 2 million clicks is a fraction of what enterprise platforms charge for similar volume.

Migration Path: Firebase to WarpLink

The full migration process is covered in our Firebase Dynamic Links Migration Guide. Here's the overview.

Step 1: Create Your Account and Register Your App

Sign up at warplink.app (free, no credit card). Create an organization and register your app with your iOS bundle ID and/or Android package name. WarpLink generates the AASA and assetlinks.json files automatically.

Step 2: Replace Link Creation

Firebase (before):

// Firebase Dynamic Links REST API
const response = await fetch(
  `https://firebasedynamiclinks.googleapis.com/v1/shortLinks?key=${apiKey}`,
  {
    method: 'POST',
    body: JSON.stringify({
      dynamicLinkInfo: {
        domainUriPrefix: 'https://example.page.link',
        link: 'https://myapp.com/products/123',
        androidInfo: { androidPackageName: 'com.myapp' },
        iosInfo: { iosBundleId: 'com.myapp.ios' }
      }
    })
  }
);

WarpLink (after):

// WarpLink REST API
const response = await fetch(
  'https://api.warplink.app/v1/links',
  {
    method: 'POST',
    headers: {
      'Authorization': 'Bearer wl_live_xxx',
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      destinationUrl: 'https://myapp.com/products/123',
      iosDeepLink: 'myapp://products/123',
      androidDeepLink: 'myapp://products/123'
    })
  }
);

Step 3: Replace SDK Integration

Firebase iOS (before):

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

WarpLink iOS (after):

// WarpLink SDK
WarpLink.handleDeepLink(url) { result in
  switch result {
  case .success(let deepLink):
    navigate(to: deepLink.path, params: deepLink.queryParameters)
  case .failure(let error):
    print("Deep link error: \(error)")
  }
}

Step 4: Recreate Existing Links

Use the WarpLink API to batch-create links that match your existing Firebase Dynamic Links. Map your Firebase link parameters to WarpLink's link creation API. The migration guide includes a complete parameter mapping table.

Step 5: Update Your Domain Configuration

If you're using a custom domain, point your DNS to WarpLink and configure the domain in the dashboard. WarpLink handles SSL and the well-known configuration files automatically.

The full migration takes about 30 minutes for most apps. The Firebase Dynamic Links Migration Guide walks through every step in detail.

Getting Started

WarpLink was built from the ground up to be the Firebase Dynamic Links alternative that developers actually want to use. Not the cheapest enterprise platform. Not a DIY hack. A purpose-built deep linking solution with transparent pricing, open source SDKs, and performance that Firebase never matched.

Here's how to get started:

Create a free account at warplink.app. No credit card required.
Follow the quickstart guide to create your first deep link in under five minutes.
If you're migrating from Firebase, read the Firebase Dynamic Links Migration Guide for a step-by-step walkthrough.
For deep linking fundamentals, the Complete Guide to Deep Linking covers universal links, app links, deferred deep links, and attribution from the ground up.

The free tier includes 10,000 clicks per month, full API access, deferred deep links, install attribution, and real-time analytics. That's enough for most apps in development and early production.

Firebase Dynamic Links is going away. Your links don't have to.
