AppsFlyer vs Branch for Deep Linking — and When You Need Neither
If you are comparing AppsFlyer and Branch purely on deep linking, the honest answer is that they are close. Both route links through an SDK, both handle deferred deep linking, both work on iOS and Android. What actually separates them is everything around the links — attribution, fraud prevention, web-to-app tooling. This page covers that difference, and then the question most comparisons skip: whether you needed a measurement platform at all.

What is the difference between AppsFlyer and Branch for deep linking?
For the deep linking itself, very little. Both are mobile measurement platforms that route links through an SDK embedded in your app, and both support direct and deferred deep linking on iOS and Android. They diverge on what surrounds the links: AppsFlyer is organised around attribution accuracy and ad-fraud prevention for large paid-acquisition budgets, while Branch leans toward web-to-app conversion, cross-device journeys, and self-service tooling marketers can drive without an engineer. Pick between them on the attribution question. The deep-linking capability is close enough that it should not decide it.
Under the hood both rely on the same operating-system mechanism you would use without them. iOS reads an apple-app-site-association file to decide whether a URL belongs to your app; Android reads assetlinks.json. The SDK does not perform the routing — the OS does. What the SDK adds is the ability to observe what happened afterwards and tie it back to a campaign.
That is the whole trade. An SDK buys you measurement; it does not buy you working links.
Which one fits which team
Choose AppsFlyer
- • Attribution is your source of truth for marketing ROI
- • Significant spend across several ad networks
- • Ad fraud is a live concern in your vertical
- • You feed install and event data into a wider BI stack
- • Enterprise procurement, security review, dedicated support
Choose Branch
- • Web-to-app conversion is a core growth lever
- • Marketers need to create tracked links without an engineer
- • Cross-device journeys matter more than single-touch install data
- • You want deep linking and growth tooling in one place
- • Referral or viral mechanics are central to the product
Choose neither
- • You need links that open the right screen, not campaign measurement
- • You already have analytics and do not want a second tracker
- • Third-party code in the binary is a cost you would rather not carry
- • Privacy posture or review process makes SDKs expensive
- • A published price beats a sales call
A useful test: open your MMP dashboard and look at what you actually read each week. If it is click counts and whether links opened the app, you are paying a measurement platform to be a link host.
How does SDK-free deep linking differ from AppsFlyer and Branch?
An SDK-free host serves the same two association files an MMP would, and lets the operating system do the routing. Nothing is added to your dependency graph, there is no library to re-integrate when iOS or Android changes, and no third-party code observes your users after the click. The cost is everything that requires code inside the app: attribution, in-app events, fraud detection, cross-device identity.
Direct deep linking genuinely involves no vendor code — a tap resolves through the OS. The one place SDK-free does not mean zero code is deferred deep linking, and we would rather be precise than sell a slogan: DeepTap returns the saved destination through a single HTTPS GET on first launch, about fifteen lines with your platform standard networking. Full samples are in the iOS and Android guides.
The maintenance difference is the part teams underestimate. An SDK is a versioned dependency inside your binary that you re-integrate on someone else's schedule — and the schedule has been busy, between App Tracking Transparency and Google's Privacy Sandbox work. Native Universal Links and App Links are maintained by Apple and Google as part of the platform.
App size is a secondary but real factor. Google Play has published data showing install conversion falls measurably as app size grows, with the effect strongest in markets where data and storage are constrained. We are not going to attach a precise figure to your app — the point is directional, and it favours carrying fewer dependencies.
A technical detail most comparisons get wrong
You will often read that iOS fetches your association file on every tap, and that a slow or unavailable host makes Universal Links fall back to Safari. That has not been how it works since iOS 14. Apple's CDN retrieves the file when your app is installed or updated, and the device uses the cached result.
The practical consequence is less forgiving, not more: a malformed file, a redirect, or a wrong content type does not produce a visible error. Universal Links simply stop opening your app for everyone who installed during that window, and you may not notice for days. Serving that file correctly and consistently is the actual job — which is why we give away a validator that works on any domain, including ones that have nothing to do with us.

What setup actually involves
With an MMP you add the SDK through your package manager, initialise it in your launch sequence, instrument the events you care about, wire deep-link routing, and QA attribution across acquisition sources. Then you keep doing the integration work as versions ship.
With DeepTap you pick a subdomain such as myapp.deeptap.io — there is no DNS to configure, because we host it. You enter your Bundle ID and Team ID for iOS and your package name and signing fingerprints for Android, then add the associated domain in Xcode and an intent filter in your manifest. Those last two are native platform configuration that every option on this page requires, including the MMPs. Custom branded domains are available on the Pro plan.
Or hand it to your coding agent: DeepTap ships a hosted MCP server with OAuth 2.1, so Claude Code or Codex can create the domain, set the credentials, and verify the result. Neither AppsFlyer nor Branch offers that.
An honest note on deferred deep linking accuracy
DeepTap matches a click to an install using a server-side fingerprint built from the client IP and the device platform, within a short window after the click — the same SDK-free approach the big platforms use as their fallback. It is most reliable when the click and the first app launch happen on the same network. Behind CGNAT, a VPN, or iCloud Private Relay, or when the device changes network between click and launch, the match can fail: your app still opens, just without the saved deep-link context. No fingerprint method avoids this entirely without an SDK in your app, which is the trade we deliberately do not make. We also do not publish a headline match-rate percentage, because anyone quoting you one number is guessing.
Frequently asked questions
What is the core difference between AppsFlyer and Branch for deep linking?
For the deep linking itself, very little. Both are mobile measurement platforms that route links through an SDK in your app, and both handle direct and deferred deep linking on iOS and Android. They diverge on what surrounds that: AppsFlyer is built around attribution accuracy and ad-fraud prevention for large paid-acquisition budgets, while Branch leans toward web-to-app conversion, cross-device journeys, and self-service tools marketers can use without an engineer. Choose between them on the attribution question, not the deep-linking one.
Do I need a measurement platform just to get deep links working?
No. iOS Universal Links and Android App Links are operating-system features. The OS decides whether a URL opens your app by reading two files hosted on the link domain, and no vendor SDK is involved in that decision. An MMP bundles deep linking with attribution because attribution is what it sells; if you do not need attribution, you are paying for a measurement platform to act as a link host.
What does DeepTap not do that AppsFlyer and Branch do?
Ad attribution, in-app event tracking, fraud detection, cross-device identity resolution, web-to-app banners, and marketing-stack integrations. None of those are possible without code running inside your app. DeepTap does provide click analytics — volume over time, device and platform breakdown, referrer, and whether each click opened the app or fell through to the store — but that is link reporting, not campaign attribution.
Is SDK-free deferred deep linking really SDK-free?
There is no SDK and nothing added to your dependency graph, but deferred deep linking is not zero code. DeepTap stores the destination when the click happens and returns it on first launch through a single HTTPS GET to its API — roughly fifteen lines using your platform standard networking. Direct deep linking, by contrast, needs no DeepTap code at all: the operating system routes it.
How accurate is deferred deep linking without an SDK?
DeepTap matches a click to an install using a server-side fingerprint of the client IP and the device platform, within a short window after the click. It is most reliable when the click and the first app launch happen on the same network, and it degrades behind CGNAT, VPNs, iCloud Private Relay, or a network switch between click and launch. When the match fails the link still opens your app, just without the saved context. We do not publish a single match-rate percentage because the honest answer depends on your traffic mix.
Can I run DeepTap alongside AppsFlyer or Branch?
Technically yes, but it rarely makes sense long-term — you would be paying for two link layers. The one case where it is reasonable is a migration, where you point new links at DeepTap while old links keep resolving through the incumbent until their traffic dies off. You cannot get attribution from an MMP without its SDK, so this is not a way to keep attribution while dropping the SDK.
What does each platform cost?
DeepTap is self-serve and published: $5.99, $14.99, or $49.99 per month depending on domains, active short links, and analytics retention. AppsFlyer and Branch both offer a free tier and then price against monthly active users or conversions, with growth and enterprise pricing quoted on request. Check their own pricing pages for current numbers rather than trusting any vendor comparison, this one included.
