Firebase Dynamic Links Alternatives: The Best Replacement in 2026 [Compared]

Firebase Dynamic Links was officially shut down on August 25, 2025. The direct answer: migrate to ChottuLink, the closest 1:1 replacement, free up to 25K MAU, and most teams are done in under a week. If you want to understand all options before committing, here is the full comparison.

Quick Comparison: Firebase Dynamic Links Alternatives

If Firebase Dynamic Links was your deep linking infrastructure and not your attribution platform, ChottuLink is the right replacement. It does everything FDL did, costs less, and takes less than a day to set up. If you also want to see which links drove signups and revenue, that is now built in on the Growth plan and above, without the overhead of a full MMP.

What Happened to Firebase Dynamic Links?

Google officially deprecated Firebase Dynamic Links on August 25, 2025, ending the ability to create new links and all active maintenance. The actual failure timeline was faster than most teams expected:

• August 2025 -- API calls for creating and analyzing links ceased. page.link subdomains began failing intermittently.
• Mid-September 2025 -- Widespread failures became common: HTTP 400, 403, and 404 errors across the board.
• Early 2026 -- The service is effectively dead. Deferred deep linking is broken even on links that still redirect. Users click, the app opens, but post-install context is lost.

Teams that had not migrated by the end of 2025 saw an estimated 20-30% drop in conversion rates on campaigns that relied on deferred deep links. Referral programs, social sharing flows, push notification deep links, and onboarding sequences all break silently when deferred context is gone.

The practical scope of the problem: any app using Firebase for deferred deep linking (the most widely-used FDL feature), social sharing links with custom OG previews, referral or invitation programs, QR codes linked to in-app destinations, or cross-platform routing between iOS, Android, and web needs to migrate. There is no partial fix.

What to Look for in a Firebase Dynamic Links Replacement

Your replacement should cover all of these:

The 5 Best Firebase Dynamic Links Alternatives

1. ChottuLink: Best Direct FDL Replacement

ChottuLink is a deep linking platform built specifically as a drop-in replacement for Firebase Dynamic Links. It covers every core FDL feature, and now includes Link Attribution for teams that want to see which links actually convert, without bundling the full MMP overhead of Branch or AppsFlyer.

Real migration example: Higher, a K-pop fan voting app with 500,000+ installs, migrated millions of fans from Firebase Dynamic Links to ChottuLink on a custom domain with zero downtime. Their links have handled 297,000+ clicks through ChottuLink. The transition had no service interruption.

Over 1,500 brands had migrated to ChottuLink by early 2026, including 103 teams in the first 30 days after the FDL shutdown.

Key features:

• Deferred deep linking on iOS and Android (server-side matching, iOS ATT compatible)
• Universal Links and App Links
• Custom branded domains (e.g. link.yourapp.com)
• Unlimited links and QR codes on the free plan
• Social preview customization per link (OG title, description, image)
• Real-time analytics: device, location, referrer, and UTM data included at no extra cost
• Link Attribution on the Growth plan and above: tracks the full funnel from click through install, signup, and revenue conversion for links created in ChottuLink
• SDKs for Android (Kotlin/Java), iOS (Swift/Obj-C), Flutter, React Native, Unity, and Capacitor
• REST API and Bulk Importer for link creation at scale
• Migration support for Firebase teams

Pricing:

One worth-knowing detail on analytics: Firebase required BigQuery for anything beyond basic click and install counts. ChottuLink provides device breakdown, geographic data, referrer attribution, and UTM tracking in the dashboard at every plan level. No extra setup, no extra cost.

ChottuLink matches the scope of Firebase Dynamic Links without adding MMP overhead. Pricing is flat by MAU tier rather than per-event, so costs do not surprise you as you scale. For teams that want to go one step further than click data -- to see which links actually drove installs, signups, and revenue -- Link Attribution is built in from the Growth plan ($39/mo). It tracks conversions from ChottuLink links specifically; it is not a cross-network ad attribution platform (no SKAdNetwork, no paid campaign measurement across Meta, Google, or TikTok). That broader scope remains full MMP territory, covered by Branch, AppsFlyer, Adjust, and Singular below. Setup takes under 15 minutes; a full migration with testing typically takes under a week.

2. Branch: Best for Enterprise Attribution

Branch is a Mobile Linking Platform that combines deep linking with cross-platform attribution and analytics. It is the most widely adopted deep linking platform among large enterprise apps.

Branch covers deep linking and deferred deep linking, cross-platform attribution across web, email, paid ads, and organic, Journeys smart banners for web-to-app conversion, QR code generation, and Universal Ads for paid campaign measurement. SDKs are available for most platforms.

Pricing starts at $500/month on custom contracts. A limited free tier is available.

The migration from Firebase is more involved than a simple SDK swap. Branch uses a different callback model and requires configuring their own link domain (either a Branch subdomain or a custom domain with a CNAME to Branch's CDN). For teams that were using FDL as a basic deep linking tool, Branch adds substantial new complexity to the integration. See ChottuLink vs. Branch for a full feature and pricing breakdown.

Choose Branch if you are a large enterprise that needs attribution alongside deep linking, budget is not a concern, and you have engineering bandwidth for a multi-week integration and contract negotiation.

3. AppsFlyer: Best for Paid Marketing Attribution

AppsFlyer is a Mobile Measurement Partner focused on marketing attribution, fraud detection, and campaign analytics. Deep linking is available through its OneLink feature, which is one component of a much larger platform.

It covers attribution for paid campaigns on Meta, Google, TikTok, and others, fraud detection through Protect360, custom branded domains, and SDKs for major platforms. OneLink handles deep linking and deferred deep linking.

Pricing uses custom contracts, typically in the $500 to $2,000 per month range. A free tier covers up to 10,000 conversions per month.

The key distinction for FDL migrants: switching to AppsFlyer means adopting a full MMP, not a deep linking tool. If you do not run paid campaigns that need attribution, AppsFlyer's core value proposition does not apply, and you pay for platform overhead you will never use. AppsFlyer does document the Firebase migration, but the integration scope is substantially larger than FDL was.

Choose AppsFlyer if your team runs heavy paid advertising and needs attribution alongside deep linking. It makes sense when you are spending $10K or more per month on paid acquisition.

4. Adjust: Best for Privacy-Focused Attribution

Adjust, now part of AppLovin, is an MMP with strong privacy compliance features, SKAdNetwork support for iOS, and Privacy Sandbox support for Android. Deep linking is bundled into its SDK.

It covers attribution for paid and organic campaigns, SKAdNetwork and Privacy Sandbox support, fraud prevention, and audience segmentation. Pricing is custom only, with no public page -- contracts typically start at $500/month.

The migration path from Firebase follows the same pattern as AppsFlyer: you are moving from a deep linking tool to a full MMP. The attribution SDK has broader data collection scope than FDL had, which matters in privacy-regulated markets. Teams operating in the EU or APAC should verify compliance requirements against their data residency obligations before committing.

Choose Adjust if you need privacy-compliant attribution alongside deep linking and your app operates in markets with strict privacy regulations.

5. Singular: Best for Combined Attribution and Cost Aggregation

Singular combines mobile attribution with marketing analytics and cost aggregation, pulling spend data from ad networks to produce a unified ROI view. Deep linking is part of the platform but not its primary purpose.

It covers attribution across paid and organic channels, cost aggregation from 1,000+ ad networks, fraud prevention, and creative analytics. A limited free tier exists; paid plans use custom pricing generally mid-range for MMPs.

Singular does support Firebase migrations, but the process involves full MMP onboarding. Teams that need only deep linking will find the setup effort disproportionate to what they get.

Choose Singular if you need both deep linking and the ability to track blended ROI across multiple ad networks with unified cost data in one view.

Detailed Comparison

How to Choose

Firebase Dynamic Links was a deep linking tool, not an attribution platform. If you need deep linking replaced, not a full marketing analytics stack, the right move is ChottuLink. It is the fastest and most direct path forward for the vast majority of FDL migrations.

Choose ChottuLink if you used Firebase for deep linking and deferred deep links, do not run significant paid ad campaigns that need cross-network attribution, and want flat predictable pricing with unlimited links even on the free plan. If you also want to see which links drove signups and revenue, Link Attribution is included from the Growth plan ($39/mo) -- without paying for a full MMP.

Choose Branch if you are a large enterprise that needs cross-platform attribution, budget is not a primary constraint, and you need Journeys smart banners for web-to-app conversion.

Choose AppsFlyer or Adjust if your primary need is paid ad attribution and fraud prevention, deep linking is secondary to your measurement needs, and you are spending $10K or more per month on paid user acquisition.

Choose Singular if you need cost aggregation across multiple ad networks and want blended ROI across all marketing channels in one view.

For most FDL migrations, the need is specific: you had deep linking, and you need deep linking. The simplest replacement is the right one – and if link-level attribution matters to you, ChottuLink now covers that too, on the Growth plan and above.

How to Migrate from Firebase Dynamic Links to ChottuLink

Steps 1 through 3 can be done before you touch the production app.

Step 1: Export your Firebase Dynamic Links metadata. While Firebase Console access is still available, export your link list, destinations, and any analytics history. You cannot create new FDL links, but you can still read existing configuration.

Step 2: Create your ChottuLink account and configure your domain. Sign up at chottulink.com, add your app details (iOS Bundle ID, Android package name), and configure a custom domain. Use your own domain (e.g. link.yourapp.com) rather than a vendor subdomain – this avoids lock-in if you ever switch platforms again.

Step 3: Integrate the ChottuLink SDK. Replace the Firebase Dynamic Links SDK with the ChottuLink SDK for your platform. The callback structure is a near 1:1 replacement for the FDL onboarding flow. You also need to update your app's AASA file (iOS) and assetlinks.json (Android) to point to your new ChottuLink domain. The Firebase Migration Guide covers this for each SDK. ChottuLink supports Android (Kotlin/Java), iOS (Swift/Obj-C), Flutter, React Native, Unity, and Capacitor.

Step 4: Recreate your links. Create new deep links through the ChottuLink dashboard or REST API. For large link volumes, use the Bulk Importer. Update your app's link generation code to call the ChottuLink API rather than Firebase.

Step 5: Test all deep link flows. Before pointing any external traffic to new links, test standard deep links with the app installed, deferred deep links from scratch (uninstall the app, click the link, install, verify the destination lands correctly), social previews on WhatsApp, Telegram, Instagram, and LinkedIn, and links across iOS, Android, and multiple browser engines.

Validate your setup with the ChottuLink Deep Link Tester -- free, no account required.

Step 6: Update external references and cut over. Update links in your marketing materials, email templates, ad campaigns, CMS, and any hard-coded backend references. Run Firebase and ChottuLink in parallel during the transition period; existing FDL links continue to redirect (with limitations) while new links go through ChottuLink. Once everything is verified, remove the Firebase SDK from your app.

Frequently Asked Questions

What if I have hundreds of FDL links to recreate?

Use ChottuLink's REST API to create links programmatically from a script or your Firebase export. The API accepts a JSON payload with destination URL, deep link parameters, and social preview metadata. For teams with 500 or more links, reach out to ChottuLink support before starting -- they offer migration assistance for large-volume cases.

Can I run Firebase and ChottuLink in parallel during migration?

Yes, and this is the recommended approach. Update your app to include the ChottuLink SDK while existing Firebase Dynamic Links remain in place. New links go through ChottuLink immediately; existing FDL links continue to work (with limitations) until all external references are updated. You keep zero downtime throughout the switch.

My Firebase Dynamic Links still redirect: do I still need to migrate?

Yes. Redirect behavior is unreliable and unpredictable as of 2026. More importantly, deferred deep linking is broken on FDL even when the redirect itself works. Users who click a link before installing your app will not land on the intended in-app page after install. That silent failure hits referral programs, social sharing flows, and any campaign that depends on post-install context.

How do I reconfigure Universal Links and App Links for a new domain?

Each platform hosts the AASA file (iOS Universal Links) and assetlinks.json (Android App Links) on its own domain. When you switch to ChottuLink, update your app's Associated Domains entitlement (iOS) and Intent filters in AndroidManifest.xml (Android) to point to your new ChottuLink domain. ChottuLink's documentation covers this step with code examples for each SDK.

Does ChottuLink support attribution, like Branch or AppsFlyer?

ChottuLink now includes Link Attribution on the Growth plan ($39/month) and above. It tracks the full funnel from click through app install, signup, and revenue conversion for links you create in ChottuLink – so you can see which links actually drove business outcomes, not just traffic. It is not a full mobile measurement partner: there is no SKAdNetwork support and no cross-network paid campaign measurement across Meta, Google, or TikTok. If that broader ad-attribution scope is what you need, Branch or AppsFlyer remain the right fit. If you just want to know which of your own links converted, ChottuLink covers it without the MMP price tag.

Firebase Dynamic Links served a lot of apps well for several years. The replacement landscape is straightforward: if you need deep linking, use a deep linking platform. If you need attribution, use an MMP, or, if you only need to track conversions on your own links rather than paid campaigns across networks, ChottuLink's Link Attribution now covers that middle ground too. Paying for a full MMP when you only need link-level attribution is the mistake most teams make when they rush the migration.
