How Flinku works

From link creation to app launch, in four steps.

Step 1

Create a link

Set your iOS target, Android target, and web fallback in the dashboard. Takes 60 seconds.

Step 2

Share it

One short link works everywhere: email campaigns, paid ads, SMS, QR codes, social media.

Step 3

We route it

Flinku detects the platform, checks if the app is installed, and routes the user to exactly the right place.

Step 4

App opens the right screen

Your SDK retrieves the original link parameters, even after a fresh install from the App Store or Play Store.

Frequently asked questions

Yes. Firebase shut down Dynamic Links in August 2025. Flinku provides the same deferred deep linking functionality with a simple API, flat pricing, and SDKs for Flutter, iOS, and Android.

Deferred deep linking means that if a user clicks your link but doesn't have the app installed, they get sent to the App Store or Play Store. After they install and open the app, they still land on the correct screen - as if they never left.

Most developers complete integration in under 30 minutes. Every link automatically gets a QR code, no extra setup needed.

Yes. Flinku has a native Flutter SDK available on GitHub. iOS (Swift) and Android (Kotlin) SDKs are also available.

Links that exceed the click limit for the month will show a temporary unavailable message. You can upgrade your plan anytime to increase limits.

Yes. Custom domains are available on the Growth and Studio plans. Add a CNAME record pointing to flku.dev and your links will use your own branded domain.

Yes. The Free tier is free forever with 3 projects, 300 links, and 10k clicks/month. Paid tiers are Indie ($12/mo), Growth ($24/mo), and Studio ($39/mo), each with a 7-day free trial.

You can cancel anytime from your dashboard settings. No cancellation fees, no questions asked.
