BUILT ON GOOD DEFAULTS

Security & privacy, honestly

Sensible protections on by default and a plain-English promise about what we haven't earned yet.

HTTPS on every link

All links are served over encrypted HTTPS by default.

SSL on custom domains

Bring your own branded domain certificates are provisioned automatically.

You own your data

Export your link and conversion data whenever you want.

No credit card to start

Kick the tyres on the free tier with nothing to enter up front.

We're early no formal certifications like SOC 2 or ISO 27001 yet. We'll say so plainly here the moment that changes.

BUILT FOR MODERN ATTRIBUTION

Accurate on iOS. Honest by default.

Built for the post-IDFA world

sniffurl handles iOS 14.5+ the way modern attribution has to: deterministic matching where a user consents, deferred deep-link resolution that survives the App Store trip, and SKAdNetwork conversion values passed through, so your install data stays whole even without the IDFA. No fingerprinting shortcuts Apple rejects at review.

Deterministic, not guesswork

Every install traces to the exact link and campaign that drove it through first-party click IDs, not statistical fingerprinting. You see the real path from click to install to in-app conversion, and you can export the raw data to check our math.

sniffurl automates the process of smart routing. It detects if a user has your app installed; if they do, they are instantly redirected to the specific in-app content. If not, it routes them to the App Store or Play Store and preserves the context for deferred deep linking.

Deferred deep links route users to the appropriate App Store to install your app first, and then automatically open the correct page or offer inside the app on the very first launch.

Standard URLs often fail to open mobile apps directly, forcing users through mobile web wrappers. sniffurl ensures 100% reliable App Links and Universal Links execution with fallback configurations.

Yes, you can configure your own custom branded domains (e.g., links.yourbrand.com) and manage all app store redirections and sub-routing parameters in real time.

sniffurl auto-detects the user's platform (iOS, Android, macOS, Windows, Linux, etc.) and routes them to the configured platform target, customized fallback, or native app store seamlessly.

Simply select a plan from our pricing page, create an account, configure your custom link domain, and start creating smart deep links in seconds.

An attribute is a single tracked event we attribute back to one of your links, usually a click or an app install. Your free tier includes the first 5,000 attributes each month; you only pay once you exceed that.
