Firebase Dynamic Links Alternative: 8 Best Replacements for 2026

Firebase Dynamic Links shut down in August 2025. Here are the 8 best alternatives in 2026, compared by use case, pricing, and how easy migration actually is.

Team U2L • 15 min read

The best Firebase Dynamic Links alternatives in 2026 fall into two camps: no-code deep link generators like U2L AI, Bitly, and Dub, which replace simple share-and-open use cases for free or cheap, and SDK-based platforms like Branch, AppsFlyer, Adjust, Airbridge, and Kochava, which add full mobile attribution for teams that need it.

Firebase Dynamic Links (FDL) shut down on August 25, 2025, and every link created on it now returns a 404. If your share buttons, email campaigns, or onboarding flows depended on those links, the breakage was abrupt and unpleasant. The good news is that the deep-linking market filled the gap quickly. The not-so-good news is that the "right" replacement depends a lot on what you were actually using FDL for, and a few of the popular options carry a price tag FDL never did.

This is the comparison guide for picking your next deep-linking tool. We have grouped the 8 strongest alternatives by who they serve, called out which Google itself recommends, and walked through the migration steps so you can plan the cutover. If you only need links that open in apps with a web fallback, you can probably skip the SDK-heavy enterprise tools entirely, and we will tell you when.

Google announced the FDL sunset in late 2023 and finally pulled the plug on August 25, 2025. Every dynamic link, including yours, started returning 404s on that date. The shutdown also took down related Firebase features like email-link auth flows that depended on FDL, leaving plenty of apps with broken onboarding overnight.

Google's official deprecation FAQ recommends seven third-party replacements: Adjust, Airbridge, AppsFlyer, Bitly, Branch, Kochava, and Singular. We have added a few more options that fit specific use cases the recommended list misses, including U2L AI for the free no-login case and Dub for the open-source crowd. The lesson is the same one we drew from the Google URL shortener (goo.gl) shutdown earlier: free link infrastructure tucked inside a tech giant is borrowed, not owned.

The single biggest mistake we keep seeing in 2026 migrations: teams over-spec the replacement. FDL was free and basic. If you did not need attribution before, you probably do not need it now. Picking a $500/month enterprise platform to replace a free feature is a tax on panic.

Quick Comparison Table

Tool Type Starting Price Best For
U2L AI No-code Free, no login Creators, marketers, no-SDK teams
Branch SDK Free dev tier, paid scales App developers, deferred deep linking
AppsFlyer SDK Custom (paid) Enterprise attribution
Adjust SDK Custom (paid) Privacy-first attribution
Airbridge SDK Free tier, paid scales APAC-focused growth teams
Bitly No-code Limited free, paid Existing Bitly customers
Dub No-code (open source) Free OSS, hosted paid Open-source friendly teams
Kochava SDK Custom (paid) Enterprise MMP buyers

1. U2L AI: best free no-code replacement

U2L AI is the easiest replacement for the most common FDL use case: "I want one link that opens content in the app on mobile, falls back to the web, and just works." You paste a URL (an Instagram post, a YouTube video, an Amazon product, a Spotify track) and get a short link that opens the right app on iOS and Android, with a clean web fallback if the app is not installed. No SDK, no AASA file, no account required to start.

What lifts it above other no-code options is the platform around the deep link. You also get a URL shortener, dynamic QR codes, link-in-bio pages, and click analytics in one dashboard. For teams that ran FDL just to share links to social or shopping content, this is a near-instant migration. Browse every supported app on the supported deep links hub or compare with our best deep link generators roundup.

Best for: Creators, marketers, affiliates, and any team that used FDL for share and bio links rather than in-app attribution.

2. Branch: the developer-grade successor

Branch is the most feature-complete deep linking and mobile attribution platform on the market, and Google's own deprecation guidance points many teams here. It supports deferred deep linking, attribution, audience segmentation, and integrates with every major ad platform. If you were using FDL inside your own app for install-and-route flows, Branch is the closest one-to-one replacement.

The trade-off: Branch is an SDK-first platform, so expect engineering effort to migrate. Pricing scales meaningfully past the free dev tier into custom enterprise contracts. Worth it if you need the depth, overkill if you do not.

Best for: Product and growth teams that own a mobile app and need install attribution.

3. AppsFlyer: best for enterprise attribution

AppsFlyer is a full mobile measurement partner (MMP) with deep linking baked in via its OneLink feature. It is built for teams who already think in terms of channels, cohorts, and ROAS, and who run paid acquisition at scale. Coming from FDL, AppsFlyer feels like trading a Honda for a tractor, more powerful, but absolutely not the same vehicle.

Pricing is custom and lands in enterprise territory. Setup involves SDK integration plus event configuration. Only consider this if you need attribution as a first-class capability, not just deep links.

Best for: Large mobile app teams with paid-acquisition budgets.

4. Adjust: privacy-first MMP

Adjust (now part of AppLovin) is another enterprise MMP with strong privacy features, SKAdNetwork support, and SDK-based deep linking. It overlaps heavily with AppsFlyer in scope and capability, with the differentiation usually coming down to existing ad-network integrations and account team fit. Pricing is custom.

If your FDL usage was for tracking, not just routing, Adjust is one of the names on the shortlist. Like the other MMPs, it is wildly overscoped if you just need links that open in apps.

Best for: Enterprise teams that prioritize privacy compliance and attribution accuracy.

5. Airbridge: APAC-strong attribution

Airbridge is an MMP with deep linking, strong APAC market presence, and a meaningful free tier that makes it more approachable than AppsFlyer or Adjust for smaller teams. The feature mix sits between a no-code tool and a full MMP, useful if you want some attribution without committing to an enterprise contract.

Best for: Mid-market apps, especially with Asia-Pacific user bases.

Bitly added mobile deep linking to its paid plans, putting it on Google's recommended list mostly because of brand recognition rather than depth. It is a fine pick if your team already uses Bitly for short links and just wants to add the mobile-app opening behavior without adopting a second tool. Free tier is limited, and the deep-link feature lives behind paid plans. For a fuller picture, see our Bitly alternatives guide and our Bitly pricing breakdown.

Best for: Existing Bitly customers who want minimal tool sprawl.

7. Dub: open source for technical teams

Dub is a modern open-source link management platform that has gained traction with developer-led teams. It offers a clean self-hosting story and a hosted plan, plus a modern API that fits well into existing dev workflows. Its deep-linking depth is closer to a shortener than to Branch, but for teams that prize open source and want to control the stack, it is a strong pick.

Best for: Engineering-led teams that prefer self-hosted or open-source tooling.

8. Kochava: enterprise MMP with deep linking

Kochava is one of the oldest mobile measurement partners and offers a deep-linking layer alongside its attribution suite. It serves large brands and agencies and is rarely the right choice for a small-to-mid team. Setup is heavy, pricing is custom, and the feature set is overkill for share-link replacement.

Best for: Enterprise teams already standardized on the Kochava ecosystem.

No-Code vs SDK: Which Type Do You Need?

The single most important question when migrating off FDL is whether you genuinely need a developer SDK or whether a no-code tool covers your use case. Most teams overestimate their need for SDKs because FDL was free, so the cost of "going big" was hidden.

Pick a no-code tool (U2L AI, Bitly, Dub) if any of these are true:

  • You used FDL mainly for share links, bio links, or email/CRM links that opened in apps
  • You do not own the destination app (you are linking into Instagram, YouTube, Amazon, etc.)
  • You do not need post-install routing into your own app
  • You do not run paid user acquisition that depends on attribution
  • You want links live this week, not next quarter

Pick an SDK platform (Branch, AppsFlyer, Adjust, Airbridge, Kochava) if all of these are true:

  • You own the destination mobile app and ship updates to it
  • You need deferred deep linking, the user installs the app, and the original target screen still opens
  • You measure installs, events, and revenue per channel
  • You have engineering capacity to integrate an SDK and configure events

The cost of guessing wrong is real. Pick an SDK when you need a no-code tool, and you spend weeks integrating something you will not use. Pick a no-code tool when you need an SDK, and you ship link routing that cannot prove its own ROI. For the deeper framing, see app opener vs deep link vs smart link.

Migration in 2026 is recovery work, FDL is already dead and your old links return 404. The plan splits cleanly by tool family.

Migrating to a no-code tool (e.g., U2L AI)

  1. Inventory your live FDL usage. Find every place an FDL URL still lives, bio pages, email templates, social posts, in-app share sheets, support docs. A simple text search of your codebase and your CRM templates surfaces most of them.
  2. Map each FDL URL to its intended destination. A YouTube video, an Instagram profile, an Amazon product, a song, a website. Write the destination URL down for each one.
  3. Create a replacement smart link in your new tool. With U2L AI, paste the destination URL and copy the new short link. Optionally set a custom back-half like u2l.ai/spring-sale.
  4. Swap the FDL URL for the new link in every location from step 1. Most of this is a find-and-replace in templates and a manual fix in social bios.
  5. Verify on a real device. Tap each migrated link on iPhone and Android with the destination app installed and uninstalled. The app should open when present; the web fallback should appear when not.
  6. Set up click tracking. Free analytics on every U2L link let you see whether the migration recovered the traffic the FDL URLs used to drive.

Migrating to a developer SDK (e.g., Branch)

  1. Audit FDL usage as above, but include any code paths that programmatically generated FDL URLs.
  2. Integrate the new SDK in your iOS and Android apps. Plan a sprint, this is not a 30-minute job.
  3. Replicate domain verification. New AASA and assetlinks.json files pointing at the new provider's domain (or your own custom domain through the provider).
  4. Recreate your link templates in the new platform. Branch and the MMPs all support templated deep links with similar semantics to FDL.
  5. Reroute deferred deep linking flows through the new SDK. Test the install-then-open journey on a fresh device.
  6. Cut over server-side link generation so anywhere your backend used to create FDLs now creates the new provider's links.
  7. Verify attribution in the new dashboard before turning paid campaigns back on.

Plan 1 to 3 days for a no-code migration, 2 to 6 weeks for an SDK migration depending on scope.

Common Migration Mistakes

A handful of patterns we see causing pain in 2026:

  • Overscoping the replacement. Buying enterprise attribution to replace free share links. We said this twice already because it is the single most common error.
  • Forgetting hardcoded FDL links. Old email templates, archived social posts, and partner marketing materials. They are all still showing 404s.
  • Skipping device testing. Universal Links and Android App Links break in subtle ways. Test with the destination app installed AND uninstalled, on iOS AND Android.
  • Not setting a custom domain early. Migrating once is bad; migrating twice when your goo.gl/foo provider also sunsets is worse. Use a custom domain with your new provider so the deep-link host is yours forever.
  • Ignoring in-app browsers. A link that opens "in the app" still fails if the click happens inside Instagram's webview. Make sure the new provider handles in-app-browser escapes; see our piece on why links open in an in-app browser for the why.

Frequently Asked Questions

For most teams, the best replacement is a no-code deep link generator like U2L AI. It covers the common share-and-open use case for free with no login, no SDK, and no AASA file to configure. If you need deferred deep linking into your own app or full mobile attribution, Branch is the closest SDK-grade successor; AppsFlyer, Adjust, Airbridge, and Kochava are the enterprise MMP options.

Google shut down Firebase Dynamic Links on August 25, 2025. All FDL URLs created before that date now return 404, and the FDL APIs no longer create new links. The shutdown was announced in late 2023 to give teams time to migrate.

Yes. U2L AI lets you create app-opening deep links for free without an account for common destinations, and Branch has a free developer tier for app teams. Dub's open-source version is free if you self-host. The enterprise MMPs (AppsFlyer, Adjust, Kochava) are paid.

Which alternatives does Google itself recommend?

Google's deprecation FAQ recommends Adjust, Airbridge, AppsFlyer, Bitly, Branch, Kochava, and Singular as third-party replacements. The list is partial, it covers attribution-grade platforms but leaves out the no-code generators that suit most teams whose FDL use was simpler.

Only if you used FDL inside your own mobile app for deferred deep linking or attribution. If your FDL links were for sharing, email, social, or CRM, a no-code tool replaces them with no integration work. Most teams overestimate their SDK need because FDL itself was free.

No. As of August 25, 2025, FDL URLs return 404. Anywhere those old URLs live (email templates, social posts, partner content), they are now dead. The migration is also a cleanup pass to find and replace them.

What is the easiest way to migrate?

Inventory every place an FDL link lives, map each to its intended destination, recreate the link in your new tool, and find-and-replace across templates and posts. For most teams, a no-code tool makes this a few-days job rather than a multi-week project. For app-owned attribution use cases, plan an SDK integration with proper QA.

Is U2L AI's free plan really enough?

For share, bio, and campaign links, yes. The free plan lets you create deep links without an account, with link analytics, dynamic QR codes, and bio pages on the same dashboard. Heavier needs unlock with paid plans, see u2l.ai/pricing for current limits.

The Firebase Dynamic Links shutdown was a forced upgrade for the deep-linking market, and most teams will land on a better setup once they finish migrating. If your old FDL use was about sharing and opening links in apps, the simplest move is to pick a no-code replacement and ship it this week. Create your first link free on U2L AI or browse every supported app to start the swap.
