Branch.io alternatives: the technical evaluation

scope

A technical evaluation of Branch.io alternatives for mobile deep linking, deferred deep linking, and link attribution. Written for engineering teams evaluating their options post-FDL shutdown.

Cluster C hub: /guides/firebase-dynamic-links-replacement.

what Branch actually does

Branch's product surface is deep, but the core mechanics are:

1. Universal short links at *.app.link domains that route via Universal Links on iOS and App Links on Android.
2. Deferred deep linking preserving the original destination across cold installs.
3. Attribution — mapping link taps to install events and to in-app actions.
4. Preview metadata rendered by Branch's servers when links are shared in social apps.
5. A no-code dashboard for marketers to generate, edit, and analyze links.

You pay for Branch when you actually use all five. If you only use one or two, you're overpaying.

the alternatives

The first three are direct Branch competitors. The latter three are alternatives that work for specific subsets of Branch's feature surface.

Companion alternative pages: /guides/appsflyer-onelink-alternative, /guides/adjust-deep-links-alternative.

AppsFlyer OneLink

OneLink is the closest direct competitor to Branch. Feature parity on deep linking. AppsFlyer's strength is the deeper attribution platform — the link is part of a broader marketing-analytics product. Branch's strength is the lighter focus on deep linking specifically.

Pricing: per-install, with a free tier for small apps. Get a quote — published pricing is approximate.

Switch if: your team uses AppsFlyer for other marketing-attribution work and wants single-vendor consolidation.

Adjust

Adjust is similar in scope. Adjust's attribution focuses on fraud detection and complex multi-touch attribution models. Branch's deep-linking dashboard is slightly easier for non-technical marketing teams to operate.

Pricing: per-event, scaled.

Switch if: your team needs Adjust's fraud-detection and multi-touch attribution depth.

Native Universal Links + App Links

If you don't actually need deferred deep linking or attribution — and you should audit your existing usage to find out — the native iOS/Android primitives replace 100% of Branch's routing function for free.

Cost: zero ongoing infrastructure.

Setup: AASA file on your domain (/guides/aasa-file-explained), assetlinks.json on your domain (/guides/assetlinks-json-explained), Associated Domains entitlement in Xcode, <intent-filter android:autoVerify="true"> in AndroidManifest.xml. Walkthroughs: /guides/ios-universal-links-setup, /guides/android-app-links-setup.

What you give up:

• Deferred deep linking. Mechanism explained: /guides/deferred-deep-linking-explained.
• Attribution. Roll your own with UTM parameters + server-side analytics.
• Preview metadata. Roll your own with OG tags on your destination pages.
• The marketing-team dashboard. Build a CMS or use existing URL-shortener infra.

Switch if: your team is small, you have engineering capacity for the DIY work, and you don't have a paid-acquisition team whose budget allocation depends on attribution accuracy.

build-your-own server

If you have an infrastructure team and don't want a third-party SDK in your app, you can build the routing + deferred-deep-link mechanism yourself.

Components:

• A routing service at yourdomain.com/l/:slug that serves redirects and AASA/assetlinks-validated routes.
• Play Install Referrer plumbing on Android (clean, well-supported).
• A best-effort iOS deferred-deep-link layer (lossy post-ATT, see /guides/deferred-deep-linking-explained).
• An attribution data pipeline mapping link taps to install events.

Engineering cost: 3–8 weeks for the initial build, then ongoing maintenance as iOS ATT rules evolve. Worth it for orgs with platform teams.

Switch if: you have a hard no-third-party-code-in-app policy or your data sensitivity requires self-hosted attribution.

no-SDK hosted alternatives

This is the lane linkboo occupies, and the alternative most people don't realize exists.

For use cases that don't involve a mobile app at all — bio links, music releases, campaign tracking, creator funnels, social-share URLs — the entire Branch feature surface is unnecessary. The relevant problem is in-app browser cookie isolation (engineering breakdown), not deferred attribution.

What no-SDK hosted alternatives provide:

• Short branded HTTPS links.
• Escape from in-app browsers via the consumer-side escape flow.
• Server-rendered preview metadata.
• Click analytics.

What they don't provide:

• Deferred deep linking (no app to defer to).
• Mobile-SDK attribution.
• Install-event tracking.

For technical buyers evaluating the no-SDK path: the link.boo/api and link.boo/docs routes carry the linkboo contract surface.

the migration decision

If you're currently on Branch, ask yourself the audit question:

1. Do you use deferred deep linking? Check your Branch SDK initialization — if you don't call Branch.getInstance().initSession(...) to read deferred params on first launch, you don't use it.
2. Do you actively use Branch's attribution dashboards? If your marketing team doesn't look at them weekly, you don't use them.
3. Do your installs come primarily from paid acquisition? If organic, the attribution accuracy matters less.

Most teams answering "no" to one or more of these are overpaying for Branch. The native primitives plus a lightweight URL shortener cover their actual use case.

pricing comparison (approximate, 2025)

Published pricing is approximate and changes. Always get a quote.

the iOS deferred-deep-linking honesty check

Branch's marketing materials show high match rates for deferred deep linking. Their published numbers are typically blended across iOS and Android.

• On Android, match rates are high (~95%) because Play Install Referrer is a clean platform mechanism.
• On iOS, match rates have degraded significantly post-ATT (2021+) and post-IDFA-deprecation. Real iOS-only match rates are 40–60%.

If your app is iOS-dominated, the Android numbers don't represent your reality. Ask Branch (and any competitor) for the iOS-only number specifically.

This is why the /guides/deferred-deep-linking-explained page recommends designing your install funnel to not depend on first-launch routing — the iOS path is lossy regardless of vendor.

migration playbook

If switching off Branch:

1. Audit which Branch features you actually use (per checklist above).
2. Stand up the replacement (AASA + assetlinks.json on your domain).
3. Implement the replacement handlers in AppDelegate / MainActivity.
4. Run both Branch and the replacement in parallel for 4 weeks under a feature flag.
5. Compare attribution data (if applicable).
6. Cut over.
7. Remove the Branch SDK.
