The best deep linking tools in 2026: an honest shortlist
Branch, AppsFlyer OneLink, Adjust, LinkTrail or plain Universal Links? What each does best, what it costs, what it gives up, and how to choose.
A disclosure first: this is LinkTrail's blog, and LinkTrail is on the list. To keep it useful anyway, every option below includes what it's best at and what it gives up, the facts come from the same comparison tables we publish on our compare pages, and the list says plainly when you shouldn't pick us.
Pricing and features change. Our comparisons reflect each vendor's public positioning at our last review — check current pricing with the vendor before you commit.
What should a deep linking tool do?
Opening an installed app from a link is free: that's Universal Links and App Links. What you pay a tool for is the rest:
- Deferred deep linking — carrying the link's destination through an install, so a new user's first open lands on the right screen.
- Smart routing — one link that sends iOS, Android and desktop to the right place.
- Attribution — knowing which link, campaign and channel produced each install.
- Hosted association files — the AASA and assetlinks.json generated and kept current for you.
The shortlist at a glance
| Tool | Pricing | Free option | Best when |
|---|---|---|---|
| Branch | Contact sales for paid tiers | Free trial | You need 80+ integrations and the broadest SDK matrix |
| AppsFlyer OneLink | Published usage pricing | Free 'Zero' tier (~12K conversions/yr) | You want a full marketing cloud — clean rooms, incrementality, MMM |
| Adjust | Quote-based, by tracked users | Base tier (~1,500 attributions/12 months) | You need a mature fraud suite and a 16-platform, open-source SDK set |
| LinkTrail | $0–$49/mo plus a custom tier, self-serve | 5,000 MAU, free forever | You want published pricing and to ship the same day |
| Universal Links + App Links | Free | Free | Links only need to open an app that's already installed |
Branch
Branch pioneered mobile deep linking and is a capable, enterprise-grade platform used by a very large number of brands. It covers deferred deep linking, attribution, SKAdNetwork and hosted association files, with the widest SDK matrix in the group — iOS, Android, web, React Native, Flutter, Unity and Cordova — and a partner ecosystem of 80+ platforms.
Trade-offs: paid pricing isn't published and goes through sales; onboarding is sales-assisted. LinkTrail vs Branch has the full table.
AppsFlyer OneLink
AppsFlyer is the market-leading mobile measurement partner, and OneLink is its deep linking product. Beyond linking and attribution it offers data clean rooms, incrementality and marketing mix modelling, and the largest integration marketplace in the category. Pricing is refreshingly transparent for the category, with a free tier and usage-based paid pricing.
Trade-offs: per-conversion pricing gets less predictable as volume grows, and it's a large suite to operate if linking is all you need. LinkTrail vs AppsFlyer has the details.
Adjust
Adjust, part of AppLovin, is a mature measurement platform with deep linking, a dedicated fraud-prevention suite, and open-source SDKs across 16 platforms.
Trade-offs: pricing is quote-based by monthly tracked users, and onboarding is sales-assisted. See LinkTrail vs Adjust.
LinkTrail
LinkTrail focuses on deferred deep linking, smart routing and install attribution, with SDKs for iOS, Android, React Native and Flutter. Every tier is published — free to 5,000 monthly active users, then $19 and $49 a month, plus a custom Scale tier — and there are no overage fees. It never reads advertising identifiers, gates attribution behind consent by default, and publishes its attribution methodology.
Trade-offs: a smaller integration ecosystem and SDK matrix than the big suites, no clean rooms or marketing mix modelling, and ad-network integrations that are inbound only — click IDs and cost imports, no postbacks. If you need those, one of the three above is the better choice.
Universal Links and App Links, self-hosted
The operating systems' own links are free: host the apple-app-site-association and assetlinks.json files and an installed app opens straight from a link.
Trade-offs: no deferred deep linking — a new user lands on the home screen after installing — no smart routing across platforms from one link, no attribution, and the association files are yours to maintain. Test them with the free Universal Links validator.
Other tools worth a look
Singular, Airbridge and Kochava also offer deep linking alongside mobile measurement, and a number of newer, smaller link tools have appeared since Firebase Dynamic Links shut down. We haven't published a comparison of them, so we'll leave the assessment to their own documentation.
How to choose
- 1Do you need deferred deep linking or attribution? If not, self-hosted Universal Links and App Links may be enough.
- 2Do you need a full marketing cloud — clean rooms, incrementality, MMM, a large partner marketplace? Look at AppsFlyer, Adjust or Branch.
- 3Do you want published pricing and self-serve setup? LinkTrail, or AppsFlyer's usage pricing.
- 4Which platforms do you ship? Check SDK coverage for every one, including Unity or web if you need them.
- 5Coming from Firebase Dynamic Links? The migration guide covers what to replace.
