If users disappear after install, land on the wrong screen after clicking an ad, or your retargeting campaigns open the app to the home screen instead of the relevant product page, deep linking is likely the missing piece. A good deep linking SDK routes users to exactly the right in-app destination, whether they are new installs or returning users, and keeps your onboarding flow intact from the very first tap. The five SDKs below are the most widely used options in 2026, each with a distinct strength depending on your app’s setup and growth goals.
What makes a deep linking SDK worth using?
Not all deep linking SDKs deliver the same reliability. A weak implementation means lost users after install, broken onboarding flows, and retargeting ads that open the wrong page. Before comparing options, it helps to know what separates a capable SDK from a basic one.
The most important factors to evaluate are deferred deep linking support (sending new users through the App Store or Play Store and still landing them on the right screen), cross-platform consistency across iOS and Android, integration with your attribution and analytics stack, and how the SDK handles edge cases like expired links or users who have uninstalled and reinstalled the app. SDKs that handle these scenarios reliably prevent app onboarding drop-off and reduce the friction that causes users not to open the app again after their first session.
1: Branch — the all-in-one deep linking platform
Branch is widely regarded as the most feature-complete deep linking platform available. Its core strength is deferred deep linking that works consistently across iOS and Android, including edge cases like users who install through a web browser rather than a direct app store link. This directly addresses the problem of users landing on the wrong screen after an ad click.
Beyond basic linking, Branch offers a full suite of tools including universal links, app clips support, email deep linking, and a web-to-app routing layer. It integrates with most major MMPs (mobile measurement partners) and ad platforms, so your attribution data and deep link behaviour stay connected. The Branch dashboard gives you visibility into link performance, conversion rates, and drop-off points across the funnel.
Branch suits teams that want a dedicated deep linking solution with broad coverage and do not want to stitch together multiple tools. It works well for e-commerce, fintech, and marketplace apps where users frequently arrive from multiple channels and need to land in a specific location, such as a product page or a pre-filled cart. One consideration: Branch’s pricing scales with usage, so larger apps with high link volumes should model costs carefully before committing.
2: AppsFlyer OneLink — attribution-first deep linking
AppsFlyer OneLink is the deep linking layer built directly into the AppsFlyer attribution platform. If your app already uses AppsFlyer for mobile measurement, OneLink is the most natural way to add deep linking without introducing a separate SDK dependency.
OneLink handles deferred deep linking, universal links, and retargeting scenarios where the goal is to bring a lapsed user back to a specific screen, such as an abandoned cart or a paused subscription flow. Because it sits inside the same platform as your attribution data, every link click is automatically tied to a campaign, source, and user journey without additional configuration. This makes it straightforward to see exactly where users drop off and whether a retargeting ad opened the wrong page.
OneLink is best suited for teams already invested in the AppsFlyer ecosystem who want a unified view of acquisition and engagement in one dashboard. It is less compelling as a standalone choice if you use a different MMP, since much of its value comes from the tight integration with AppsFlyer’s measurement layer.
3: Adjust — deep linking built for performance marketers
Adjust combines mobile attribution with a capable deep linking module that handles both deferred and direct deep links across iOS and Android. Like OneLink, its deep linking functionality is strongest when used alongside Adjust’s core attribution product, giving performance marketers a connected view of campaign spend and post-install behaviour.
Adjust’s deep linking supports custom redirect logic, meaning you can define fallback destinations for users on unsupported devices or older OS versions, which reduces the number of users who land in the wrong place after clicking an ad. It also integrates with Adjust’s audience builder, so retargeting segments can be linked directly to personalised in-app destinations.
Adjust is a practical choice for performance-driven teams running paid campaigns across Apple Search Ads, Google, Meta, and TikTok who want attribution and deep linking managed from a single platform. If your primary concern is measuring campaign ROI and reducing app onboarding drop-off from paid traffic, Adjust’s combined offering is worth evaluating seriously.
4: Firebase Dynamic Links — Google’s free alternative
Firebase Dynamic Links is Google’s deep linking solution, available at no cost as part of the Firebase platform. For teams building on Google’s ecosystem or those with limited budget, it offers solid deferred deep linking functionality without the licensing costs of dedicated platforms.
Dynamic Links support iOS and Android, handle App Store and Play Store redirects for new installs, and allow you to pass parameters through the install so users land in the right place on first open. Integration with Google Analytics for Firebase means you can track link performance alongside your broader Firebase event data, which is useful if Firebase is already your primary analytics layer.
The main limitation is that Firebase Dynamic Links has been officially deprecated by Google, with the service scheduled to wind down. Teams currently relying on it should plan a migration to an alternative SDK. For apps that have not yet chosen a deep linking solution, starting with Firebase Dynamic Links in 2026 is not recommended given the uncertainty around long-term support.
5: Kochava — deep linking with granular data control
Kochava is a mobile measurement and attribution platform that includes deep linking as part of its broader growth intelligence suite. Its standout characteristic is the level of granular data access it provides, making it a strong fit for teams that need detailed control over how link data is captured, stored, and used.
Kochava’s deep linking handles standard deferred and direct scenarios, and its SmartLinks feature allows you to build routing rules that direct users to different destinations based on device type, OS version, or campaign parameters. This level of conditional logic is useful for apps with complex user flows or multiple product lines where a single link destination does not fit all traffic sources.
Kochava is best suited for larger organisations or data-sensitive verticals such as fintech or healthcare where data ownership and privacy compliance are high priorities. It offers a free tier with core functionality, which makes it accessible for teams that want to evaluate the platform before committing to a paid plan. The trade-off is a steeper learning curve compared to more streamlined options like Branch or OneLink.
Which deep linking SDK fits your app?
The right choice depends on your existing tech stack, your primary growth channel, and how much of your user acquisition relies on paid advertising versus organic. If you already use AppsFlyer or Adjust for attribution, their native deep linking modules are the most efficient path since you avoid adding another SDK and keep your data in one place. If you need a standalone deep linking platform with the broadest feature set, Branch is the most capable option for teams running multi-channel campaigns where users arrive from email, social, paid ads, and organic search.
For apps experiencing users disappearing after install or cart contents being lost after reopening the app, the problem is almost always deferred deep linking that is either missing or misconfigured. Any of the four active platforms above (Branch, OneLink, Adjust, or Kochava) will solve that problem if implemented correctly. The implementation quality matters as much as the SDK choice itself.

Frequently Asked Questions
How do I know if my current deep linking setup is broken or misconfigured?
The clearest signs are users landing on the app’s home screen instead of the intended destination after clicking an ad, high drop-off rates immediately after install, or cart and session data not persisting when a new user opens the app for the first time. You can audit this by running a test campaign end-to-end — click your own ad link on a device without the app installed, complete the install, and verify whether you land on the correct screen with the expected parameters intact. If the flow breaks at any point, deferred deep linking is either missing or misconfigured.
Can I use more than one deep linking SDK at the same time?
It is technically possible but generally not recommended. Running multiple deep linking SDKs simultaneously can cause conflicts when both try to intercept the same link, leading to unpredictable routing behaviour and bloated app size. The better approach is to choose one SDK that handles deep linking and ensure it integrates cleanly with your attribution platform. If you are switching from one SDK to another, plan a clean cutover rather than running both in parallel for an extended period.
What happens to my deep links if a user uninstalls and reinstalls the app?
This is one of the more overlooked edge cases in deep linking. When a user reinstalls the app, a basic deep linking setup will typically route them to the home screen rather than the destination they originally came from. Platforms like Branch and Kochava have mechanisms to handle reinstall scenarios by storing link data and re-associating it on reinstall, but this behaviour needs to be explicitly configured and tested. If re-engagement campaigns are a significant part of your growth strategy, confirm that your chosen SDK documents and supports reinstall deep linking before committing.
Is deep linking only relevant for paid advertising, or does it matter for organic channels too?
Deep linking is just as valuable for organic channels as it is for paid. Email campaigns, push notifications, SMS, social media bio links, and QR codes all benefit from deep linking because they each send users to a specific in-app destination rather than the app’s home screen. In fact, for retention and re-engagement flows — such as bringing a lapsed user back to their abandoned wishlist or a paused onboarding step — deep linking from owned channels often has a higher ROI impact than paid retargeting. Any channel where you want to control the post-click in-app experience should route through your deep linking setup.
Now that Firebase Dynamic Links is deprecated, what is the best migration path?
The right migration path depends on your existing stack. If you already use an MMP like AppsFlyer or Adjust, migrating to their native deep linking module (OneLink or Adjust’s deep linking) is the most efficient route since it avoids adding a new SDK dependency. If you want a dedicated deep linking platform with the broadest feature coverage, Branch is the most common migration target from Firebase Dynamic Links and has published migration guides specifically for this transition. Start the migration before Google’s shutdown deadline to give yourself time to test the new setup thoroughly across both iOS and Android.
How much development effort does it typically take to implement a deep linking SDK?
A basic integration — covering deferred deep linking and universal links on both iOS and Android — typically takes one to three days of developer time for a straightforward app. The complexity increases if your app has a large number of distinct destination screens, custom routing logic, or needs to integrate with an existing attribution and analytics stack. The most time-consuming part is usually mapping out all the deep link routes and testing edge cases like expired links, unsupported OS versions, and the install-then-open flow. Investing in thorough QA at the implementation stage prevents the majority of real-world routing failures.
What is the difference between a universal link and a deep link, and do I need both?
A deep link is a URI that routes a user to a specific screen inside an app (for example, myapp://product/123), while a universal link (iOS) or App Link (Android) is an HTTPS URL that the operating system intercepts and opens directly in the app if it is installed, or redirects to the web or app store if it is not. Universal links are the more reliable modern standard because they do not require a custom URI scheme and handle the install/no-install branching automatically. In practice, a properly configured deep linking SDK like Branch or OneLink manages both layers for you, so you benefit from universal link behaviour without needing to implement the two systems separately.
